  • 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.

  • 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 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 (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.

  • 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 3.5 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 3.5 mm connection on the audio cable as it is possible that a faulty 3.5 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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:

    - 3.5mm 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 3.5mm headphone plug to an RCA connection you would use a female 3.5mm to male RCA adapter.

    For example to change an analog connection (3.5mm 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).

  • 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 2.4 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.

  • 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.

  • 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.

  • 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.
