The RS 195 is the model number refers to the complete wireless headphone system. This system consists of the transmitter TR 195 and headphones HDR 195. RS 195 508675 What should I do if my RS 195 transmitter will not turn on? With the RS 195 turning on the headphones activates the transmitter. To turn on the headphones press and hold the power button on the headphones for three 3 seconds. When the headphones are on the LED on the headphones will light up and the transmitter will activate and hence the LED on the front of the transmitter will light up GREEN. RS 195 508675 How do I connect to a DirecTV Genie Client box? DirecTV Genie Client boxes offers a non-traditional audio output that requires a special connector that you can get two ways By calling Directv and ask them for the 10 pin connector that goes in the A/V out on the back of the box You can purchase the adapter from please see link below 10 Pin connectors RCA Coupler RCA "Y" connector Needed for RS 165, 175, 195 RS 195 508675 How do I get the best transmission range out of my wireless headphones? While the overall transmission range for wireless headphones is mostly determined by the wireless technology being utilized by the individual wireless headphone product there are multiple external factors like obstacles, audio signal strength, wireless signal congestion, etc that can effect the wireless signal transmission range of wireless are one of the main factors that can effect the transmission range of the wireless signal. While the wireless signal with the exception of infrared signals can pass through obstacles like walls ultimately range will be affected likely reduced by passing through these obstacles and the more dense the obstacle the greater the effect will be on the signal. For example a signal passing through a glass window won't be affected very much whereas a signal passing through a concrete wall will be effected much more greatly. Having a clear line of sight does provide the best transmission audio signal being output by your audio source to the transmitter of the headphones is another key factor in transmission range. A weaker audio signal going into the transmitter means the transmitter has a weaker signal to work with which can in turn reduce the transmission strength which ultimately affects range. Ensure that your audio source is outputting the best possible signal for the transmitter to use. RS 195 508675 Manufacturer declaration in relation to magnetic fields and pacemakers/defibrillators RS 195 508675 Manufacturer's Declaration in relation to Pacemakers RF Compatibility RS 195 508675 What do I do if my Assistive Listening System suddenly stopped working? In a situation where a unit that has been functioning correctly has suddenly stopped functioning for no apparent reason the issue is likely an internal electronics glitch caused by a power surge. To resolve this issue an internal electronics reset is required. Disconnect the transmitter base station from both the audio source and the power source and at the same time remove the batteries from the headset. Leave the system disconnected from power and the batteries out of the headset for 15 minutes. This gives the internal electronics unit a chance to reset back to factory settings. After the reset period reconnect the system to power and put the batteries back in the headset and test the system. RS 195 508675 What is the wireless signal range of a wireless Assistive Listening System? As an industry standard the range of wireless headphones is measured "line of sight" headphones from transmitter as it is the only way for all manufacturers to measure the range in an equal effective wireless signal transmission range ie how far the headphones can get from the transmitter will vary from product to product and is determined by the type of wireless transmission signal Infrared, radio frequency, etc being used by the individual wireless headphone system. The effective wireless signal transmission range will also be affected by external factors like obstacles, audio signal strength, wireless signal congestion, etc. RS 195 508675 Why do I experience Static/Hum/Hiss when using an Infrared Assistive Listening System? Typically a static/hum/hissing sound in the infrared headset is caused by one of the following events 1 One of the RCA cables red/white is connected into an input rather than an output or the mm connection has been plugged into a digital output rather than an analog output. To resolution is to make sure the audio cable is connected into analog audio outputs. 2 There is some form of interference with the infrared beam of light from an external source ie a lamp or other form of light is disrupting the infrared light. The resolution is to remove this external interference. NOTE If the unit is connected to an LED or plasma TV the light from the screen can actually be causing the interference and we would recommend switching to a radio frequency RF model rather than use an infrared model. 3 The hiss is being created by the audio connections themselves through a faulty connection. The resolution is to try the unit on a separate independent audio source like a cable box, DVD player, iPad, stereo, etc. If the unit works correctly on the new audio source you can then determine that the issue lies with the original audio connections and new connections with the original audio source need to be established. NOTE For testing purposes we would recommend connecting directly to the audio source with the mm connection on the audio cable as it is possible that a faulty mm to RCA adapter could cause the issue. 4 The audio signal itself is corrupted and the hiss is actually part of the audio signal. This typically occurs when a cable signal is involved. The resolution is to call the cable company and request that the audio signal is reset. RS 195 508675 Why do my speakers shut off when I connect my Assistive Listening System to the headphone output? A connection to the headphone jack of any audio component ie TV, A/V receiver, computer, etc will automatically disable the speakers. If you need the speakers active so others can be enjoying the same audio we recommend connecting your Assistive Listening System to the audio outputs ie RCA, optical output, digital audio out, etc of the audio component. RS 195 508675 Why is the sound of my Assistive Listening System slightly behind the video image or speaker sound? The issue where the sound of the headphones is slightly behind the image on the TV or audio from the speakers could be caused by the latency of the headphones the time it takes to transmit sound via a wireless signal or it could be the device that the headphones are connected into and how that device is outputting the audio signal that is the issue. Latency occurs in all wireless headphones however the technology being used to create the wireless signal does affect how much latency is caused. For example a Radio Frequency RF model like the Set 840 has a latency of approximately 3 m/s whereas a KLEER digital model like the RS 160/RS 170/RS 180 has a latency of approximately 45 m/s. Usually the delay even at the 45 m/s level is not discernible and hence goes unnoticed. The component that the headphones are connected to will also affect this issue and could make the inherent latency more obvious. For example if a TV outputs sound to it's own speakers slightly faster than it outputs sound to the audio output jacks that the headphones are connected to then that would mean that there is a delay in the audio getting to the headphones on top of the latency of the headphones so the difference between audio and image would be more obvious. To overcome latency issues sometimes the component that the headphones are connected into will have a latency adjustment which can be used to adjust the component to match up with the headphones. If the component does not have a latency adjustment then a second option would be to connect the headphones directly to the audio source ie cable box, DVD player, etc so that the headphones get the audio signal slightly before the TV and hence the latency factor compensates for getting the audio signal before the TV. RS 195 508675 RF Radio Frequency RF is the acronym for Radio Frequency. Radio Frequency is a type of wireless signal. Radio Frequency signals have the ability to pass through most obstacles like walls. RS 195 508675 Can different wireless headphones be used with different transmitters? The different wireless headphone models utilize different signal transmission technologies so the compatibility and interchangeability of the different wireless headphone models is dependent on the specific wireless headphone models in question. Please review the chart below for compatibility guidelines. NOTE The special features of the various models are not applicable if you interchange models. For example if you take a set of headphones from one system like the HDR 180 headphones from the RS 180 system and pair it with a different system like the RS 170 the headphones will provide audio however the headphones will not have the additional features like Surround Sound because the headphones do not have the supporting internal electronics. RS 195 508675 Can I use wireless headphones for performance applications or music practice? Our wireless headphones are designed for home A/V use like TV watching, music listening, etc not music performance and hence we do not recommend out wireless headphones for music performance applications. The reason for this is that all wireless devices have some form of latency ie the time it takes for audio to be transmitted wirelessly. The latency of wireless headphones is fine for home A/V use but the latency is too great for performance use. You would want something like EW 300 IEM G3 to go wireless with low latency, low noise and an acceptable input-dynamic range for performance applications. RS 195 508675 How do I get sound from BOTH the TV and headphones at the same time? Having sound from BOTH the TV and the headphones at the same time is actually determined by how the headphones are connected to the audio source. Generally speaking there are a couple of ways of creating these connections which are 1 If a set top box cable box, DVR, etc is in use look for audio output jacks on this device and connect the headphones to the set top box to allow for independent operation of TV speakers and headphones. 2 Check the TV manual/set up guide for an option that allows the TV to operate the speakers and audio output jacks independently ie fixed output to allow for independent operation of TV speakers and headphones and connect into the audio output of the TV. NOTE If you have a dedicated headphone jack and use that connection it automatically cuts sound to the TV speakers. RS 195 508675 How do I get sound ONLY from the headphones and not the speakers? Having sound ONLY from the headphones and not the TV is actually determined by how the headphones are connected to the audio source. Generally speaking there are a couple of ways of creating this type of connection which are 1 Connect the headphones to a dedicated headphone jack which will usually automatically route sound from the TV speakers to the headphone jack and hence audio is only coming out of the headphone jack. 2 If a set top box cable box, DVR, etc is in use look for audio output jacks on this device and connect the headphones to the set top box to allow for independent operation of TV speakers and headphones and hence the TV volume can be turned down or muted. 3 Check the TV manual/set up guide for an option that allows the TV to operate the speakers and audio output jacks independently ie fixed output to allow for independent operation of TV speakers and headphones and hence the TV volume can be turned down or muted. RS 195 508675 How do I know if the wireless headphones will work on my audio device? Our Wireless Headphone Systems can be connected into virtually any audio device and it is just a matter of identifying the appropriate audio output port and then having the appropriate connecting plug or component. The type of connector you have available will depend on the Sennheiser Wireless Headphone System that you choose. The type of audio output that you will have available to connect into will depend on the audio device you are connecting to. Typical audio output ports include - headphone port- red and white RCA audio output ports- digital audio output either optical or coaxial NOTE In some instances an adapter or extra component will be needed to make the appropriate connection. For example to change a headphone plug to an RCA connection you would use a female to male RCA adapter. For example to change an analog connection headphone plug or red and white RCA plugs to a digital connection ie optical you would use a digital to analog decoder like the OREI DA 34. RS 195 508675 What do I do if my Wireless Headphone System suddenly stopped working? In a situation where a unit that has been functioning correctly has suddenly stopped functioning for no apparent reason the issue is likely an internal electronics glitch caused by a power surge. To resolve this issue an internal electronics reset is required. Disconnect the transmitter base station from both the audio source and the power source and at the same time remove the batteries from the headset. Leave the system disconnected from power and the batteries out of the headset for 15 minutes. This gives the internal electronics unit a chance to reset back to factory settings. After the reset period reconnect the system to power and put the batteries back in the headset and test the system. RS 195 508675 What do I do if the optical cable is not fitting correctly into the optical port? Please remove the plastic caps from the tips of the optical cable before inserting the cable into the optical port. These plastic caps are only there to protect the connectors before use. RS 195 508675 What do I do when there is wireless signal or WiFi interference? The wireless headphones that utilize a digital transmission signal operate in the unlicensed Ghz range as do many other wireless devices like WiFi routers, wireless printers, etc and the headphones have a specific frequency range on which they can operate. The headphones scan the local wireless signal environment and then automatically select an unused frequency within their designated range. The headphones are designed to work in conjunction with other wireless devices without the different devices interfering with each other. Typically the bandwidth of the WiFi router is greater than that of the headphones and it actually encompasses the bandwidth that the headphones want to use. Most of the time the two signals are away from each other and there is no issue. Occasionally if the WiFi router has established it's signal in the bandwidth that the headphones want to use then the two signals butt up against each other this can cause issues. Sometimes it is possible to change the WiFi router frequency manually by using a switch on the router itself. In situations where the WiFi router cannot be changed manually the simple solution is to turn off the headphones and the WiFi router. Start the headphones and let them run for 15 minutes to establish their signal and then turn on the WiFi router. The WiFi router will "see" the signal of the headphones and establish it's own signal in a different part of the bandwidth and the two devices will work without interfering with each other. NOTE Once this process has been done the signals are established and will remain established even with a device is turned off. If the above solution does not resolve the issue it may be a situation where the wireless environment is too crowded and the multiple wireless signals keep butting up against each other and causing issues. To resolve this some wireless signals would need to be removed from the environment ie turned off. For example if a wireless printer was turned on it is creating wireless signal that would be part of the wireless signal congestion. If the printer is not used all the time then it could be turned off to reduce the congestion and allow the other wireless devices like the headphones to work. RS 195 508675 What headphones can connect directly into a optical audio output? The number of wireless headphones regardless of manufacturer that will connect directly to a optical audio output is actually quite limited. The Sennheiser RS 175, RS 185 and RS 195 Wireless Headphones have the ability to connect directly to a digital optical output that is outputting a PCM signal. The alternate way to connect to a digital output is to use a digital to analog decoder which will take the digital signal and change it into an analog signal. When using a digital to analog decoder any analog headphones have the ability to be connected to a digital output. NOTE The Digital to Analog Decoder we recommend is the OREI DA 34 as it is a good quality component that not too expensive but does not compromise the audio quality. RS 195 508675 What is the wireless signal range of wireless headphones? As an industry standard the range of wireless headphones is measured "line of sight" headphones from transmitter as it is the only way for all manufacturers to measure the range in an equal manner. The effective wireless signal transmission range ie how far the headphones can get from the transmitter will vary from product to product and is determined by the type of wireless transmission signal being used by the individual wireless headphone system. The effective wireless signal transmission range will also be affected by external factors like obstacles, audio signal strength, wireless signal congestion, etc. RS 195 508675 Why do I only hear sound from one of my audio sources? In a situation that where there are multiple audio components ie cable box, DVD, player, etc connected and the headphones are only receiving sound from one of the audio components likely indicates that one of two scenarios is occurring. SCENARIO ONEThe transmitter is connected directly into an external audio component like the cable box and hence can only get sound from that component. To get sound from a different external component the headphones would need to be disconnect from the original external device and connect to the other external component directly. A solution to avoid having to unplug from one component and plug into the other component all the time you could use an AV switching box to create a hub where all the external components can be connected into one place. The hub will then provide outputs to run audio to the TV and audio to the headphones as well. NOTE An analog version of an AV Hub can be seen here NOTE A HDMI version of an AV Hub can be seen here SCENARIO TWOAll of the external audio components are connected directly into a device TV, Receiver, etc however the devices are utilizing different types of audio signal analog, digital, HDMI, etc and the device that the headphones are connected to can only output some of these signals in a format that the headphones can utilize. The headphones are designed to use an analog signal so this is the type of signal that the device needs to output for the headphones to use. The solutions that could be used here would be to try an get all the external audio components connected using the same type of audio signal and utilize something like the AV Hub mentioned above. Alternatively a component like a Digital to Analog Decoder or Digital Audio Decoder which will accept different forms of audio signals including multi-audio stream signals like HDMI and convert the signals back to analog for the headphones to use could also be utilized. NOTE A couple of the versions of the Digital to Analog Decoder are as follows - GEFEN Digital Audio Decoder Digital-Audio-Decoder/dp/B0021QBIBQ/ref=sr_1_2?ie=UTF8&qid=1393427713&sr=8-2&keywords=GEFEN+digital+to+analog+decoder - OREI Digital to Analog Audio Decoder RS 195 508675 Why don't all headphones have a digital/optical connection or include a digital converter? Many of the older wireless headphones manufactured by Sennheiser were designed before the digital/optical connection became as common as it is today and up until quite recently most audio devices had both RCA outputs and digital/optical outputs hence the headphones were able to be connected directly. It is not possible to retrofit older Sennheiser models to have a digital audio input as the internal electronics are designed for an analog connection/signal not a digital connection/signal. NOTE Newer wireless headphone models like the RS 175, RS 185 and RS 195 do have optical audio connections. Since a digital to analog converter/decoder is not required for all applications it is not practical and in fact would be cost prohibitive to include this kind of a component with all older headphone models. Instead if a digital to analog decoder is needed for an individual set up it would be purchased as an aftermarket accessory. A good quality digital to analog decoder is the OREI DA 34. RS 195 508675 Why don't I get audio from all sources Netflix, Apple TV, Amazon FireStick, etc? Audio coming from certain content providers or devices Netflix, Roku, Apple TV etc. typically use an advanced digital audio signal such as HDMI or advanced Dolby audio. These cannot be translated into analog or PCM by most television software and so the signal is not passed through into the headphones. As a result you may get silence or audio from a different source like your cable box. In order to resolve this, you will you will need to change the audio output format in the app or device to PCM may be in the smart hub on some TVs or you will need a digital to analog decoder. The Digital to Analog Decoder will take the advanced digital signal and decode it into an analog signal that your headphones can utilize. You will not lose audio quality as the digital signal is a carrier signal only. Any audio you hear from your TV speakers, sound bar or headphones is an analog signal. The digital signal is translated by the TV, receiver or other device by the time it reaches the transducers. The only difference is where the audio signal is translated. If your digital optical output is not in use we recommend the OREI DA34. The OREI DA 34 can be seen here If the digital optical output is already being used by a device like a sound bar you will want the J-TECHDigital to Analog Decoder because it offers both an analog output for the headphones to use and an optical output for the soundbar or other device to use. The J-TECH can be seen here Please bear in mind that we recommend these specific devices because we have tested them and know that they work. We do not recommend digital to analog CONVERTERS a different device entirely because they cannot translate the more complex digital audio signals. NOTE We do suggest looking at your TV's documentation to make sure that there are no design features that prevent certain digital signals like HDMI signals from being output through the Digital Optical output before purchase. It is possible for this feature to exist but exceedingly rare so for most applications the Digital to Analog DECODER is the optimum solution. RS 195 508675 Why do the speakers shut off when I connect my Wireless Headphones to the headphone port? A connection to the headphone jack of any audio component ie TV, A/V receiver, computer, etc will automatically disable the speakers. If you need the speakers active so others can be enjoying the same audio we recommend connecting your headphones to the audio outputs ie RCA outputs, digital optical audio output, digital coaxial audio out, etc of the audio component rather than the headphone output. RS 195 508675 Why is the headphone sound slightly behind the video image or speaker sound? The issue where the sound of the headphones is slightly behind the image on the TV or audio from the speakers could be caused by the latency of the headphones the time it takes to transmit sound via a wireless signal or it could be the device that the headphones are connected into and how that device is outputting the audio signal that is the issue. Latency occurs in all wireless headphones however the technology being used to create the wireless signal does affect how much latency is caused. For example a Radio Frequency RF model like the RS 120 has a latency of approximately 1 m/s whereas a KLEER digital model like the RS 160/RS 170/RS 180 has a latency of approximately 45 m/s. Usually the delay even at the 45 m/s level is not discernible and hence goes unnoticed. The component that the headphones are connected to will also affect this issue and could make the inherent latency more obvious.
