FAQ

  • How do I fine tune my Set 900 Assistive Listening System for the best audio?

    There are a series of adjustments on the Set 900 that can be done to adjust the audio to enhance the listening experience.

    On the transmitter:

    - Switch for Mono/Stereo = STEREO mode is different audio signals (ie: Left and Right) to each ear and MONO mode has a mixed signal (ie: Left and Right combined) that is the same sound going to both ears.

    - Speech Intelligibility Buttons = Boosts for low/medium/high frequencies (or can be turned off) for increased audio intelligibility.

    - Treble adjustment control = Adjusts treble however it is recommended to only be done by a hearing expert.

    On the receiver:
    - Balance Control = Controls how much volume each ear gets

    NOTE: On the receiver there are also external microphones that can be turned on to pick up and amplify ambient sound (like conversations in the room).

    NOTE: All of these adjustments are done assuming that the audio signal getting to the transmitter is a good clean signal. The transmitter/receiver is set to the specific frequencies so no fine tuning for frequencies is needed. If it is an issue like static in the audio then either change the transmitter channel (frequency) or check the audio source for signal issues or check for external influences that could cause the issue.

  • How do I set up my Set 900 Assistive Listening System?

    The Set 900 wireless headset system can be connected via a 3.5 mm plug into a dedicated headphone jack (which will often cut sound to the external speakers) OR to the RED & WHITE RCA audio output jacks (often found on the back of the TV, cable box, receiver, DVR, etc) and when connected in this manner they will allow for operation of both the headphones and the external speakers.

    The first step is top connect the transmitter (base station) to power and the second step is to connect the audio cable to the audio source. When the audio cable is connected to an audio source that is turned on the first thing to check is that the GREEN light on the front of the transmitter (base station) comes on. This indicates that the unit has both power and is transmitting audio. Once this GREEN light comes on it is simply a positioning the receiver (headset) within the transmission range of the transmitter. NOTE: The Set 900 is infrared so the transmitter and receiver must be facing each other to work correctly.

    If the GREEN light doesn't come on or comes on and then goes away when the transmitter is plugged into both a power source and an audio source then it means that the audio signal is is too low (or not getting to the transmitter at all). The transmitter needs a nice, loud signal to work with or the internal electronics will shut off within 5 minutes if no/very little volume is detected to conserve battery life. The signal level needs to be increased before reaching the transmitter. This can be accomplished by turning up your source on variable-level outputs (TV Volume) or by increasing the signal from a fixed-level output (increasing the output level to the audio output jacks which is done through the TV set up options). Try increasing it in small increments to prevent overload which results in distortion. Also check to see that you are connected to outputs and not inputs. You may also try to connect to a cable box (or DVR, HD receiver, etc) and its audio outputs or through a headphone plug. 

    NOTE: If there is no analog audio output available on your audio source and the only option for connecting the headphones is a digital audio output then a digital to analog decoder would be needed to connect to the digital output to change the digital signal to an analog signal for the headphones to use. A good digital to analog decoder is the OREI DA 34 (http://www.amazon.com/Orei-DA34-Digital-5-1-Channel-Headphone/dp/B008EPW7O0/ref=sr_1_1?ie=UTF8&qid=1412708965&sr=8-1&keywords=orei+DA+34)

    The other lights that appear on the transmitter (base station) are the battery charging indicator lights. There is one light to indicate charging when the headset is in the charging cradle and one light to indicate charging if a battery is in the side charging slot. These lights will light up RED when the battery is charging and turn GREEN when the battery is fully charged.

    There are three lights are on the left hand side of the transmitter (base station) and these indicate the frequency boost functions. If the frequency boost function is not activated then no light will appear. If the frequency boost function is activated then the light will appear to indicate which level (low frequencies, mid range frequencies or high frequencies) is being boosted. To change from one level to another simply push the frequency boost button.

  • What do I do if the volume control of the Set 900 has stopped working?

    On the front of the receiver (the part that you wear) is a large black volume dial. This large dial acts like a "cog" and turns a smaller internal volume dial. In a scenario where the volume control of the Set 830 or Set 840 does not appear to be functioning correctly it may be a situation where the dials are out of alignment.

    The solution is to realign the dials. To do this follow these steps:

    Step 1: Remove the large black dial. (It pops straight off).
    Step 2: Turn the volume all the way down by adjusting the small internal dial. (The small dial is grey colored and about the size of a dime).
    Step 3: Re-align the large black dial with the "0" just to the RIGHT of the "12 o'clock" position and click it back into place.
    Step 4: Test the volume.
    Step 5: You're all set.

  • What is the transmission range of my Set 900 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.

    With infrared systems the audio is transmitted via a beam of infrared light. In order to operate the receiver (headset) must be able to "see" the infrared light being created by the transmitter (base station) hence the receiver must be "line of sight" to the transmitter. If the receiver is not "line of sight" to the transmitter or is too far to one side/up/down and is outside of the infrared coverage area or something blocks the light between the transmitter and receiver the audio signal would be interrupted. If the receiver goes beyond the range of the infrared light (ie: too far away from the transmitter) the infrared light will have dissipated and the receiver will no longer be able to detect the infrared light. For optimal range ensure that the transmitter is placed to provide a clear line of sight to the receiver. Often placing the transmitter is an elevated position with a slight downward angle to the receiver is optimal.

    To increase range Sennheiser recommends trying to increase the audio output signal of the audio device that you have the transmitter connected to. Another factor that can affect range for an infrared system is lighting within the room. Some light (especially concentrated light like a lamp) will cause the infrared light to dissipate more quickly so ensure that the transmitter and receiver is not directly next to a concentrated source of light.

  • Assistive Listening Systems Product Descriptions & Basic Differences

    Sennheiser offers a range of wireless headset options that utilize a variety of audio transmission signals (Infrared and Radio Frequency) and a variety of wearing styles to suit different wearing preferences.

    These headsets can be connected via a 3.5 mm plug into a dedicated headphone jack (which will often cut sound to the external speakers) OR to the RED & WHITE RCA audio output jacks (often found on the back of the TV, cable box, receiver, DVR, etc) and when connected in this manner they will allow for operation of both the headphones and the external speakers. All models offer unique functions yet will be able to provide an excellent listening experience and personal preference will play a large part in selection.

    Our range of wireless headphones can be seen on our website (http://en-us.sennheiser.com/wireless-headphones).

    NOTE: We do NOT recommend Bluetooth headsets for applications like TV watching as the latency (time it takes for a Bluetooth signal to be transmitted) that is inherent to all Bluetooth devices causes the audio to be out of sync with the video.

    A few quick differences to keep in mind when choosing:

    - Set 900 - (Infrared transmission - must be line of sight to the transmitter to work) (Incorporates increased audio intelligibility where the frequencies of the human vocal range are enhanced to make dialog stand out from background noise and and hence dialog is more distinct.) (Incorporates built in microphones to increase ambient sound and built in preset audio adjustment levels to adjust for different types of hearing loss.) (Volume to each ear can be adjusted independently and the transmitter can be set to stereo or mono sound.)
    - Set 840 TV - (Radio Frequency transmission - you don't have to be line of sight to the transmitter and can move around within the range of the transmitter). (Incorporates increased audio intelligibility where the frequencies of the human vocal range are enhanced to make dialog stand out from background noise and and hence dialog is more distinct.) (Incorporates built in preset audio adjustment levels to adjust for different types of hearing loss.) (Volume to each ear can be adjusted independently and the transmitter can be set to stereo or mono sound.)
    - Set 840 S - (Radio Frequency transmission - you don't have to be line of sight to the transmitter and can move around within the range of the transmitter.) (Incorporates increased audio intelligibility where the frequencies of the human vocal range are enhanced to make dialog stand out from background noise and and hence dialog is more distinct.) (Utilizes induction loop technology to work specifically with Hearing Aids.) (Incorporates built in preset audio adjustment levels to adjust for different types of hearing loss.) (Volume to each ear can be adjusted independently and the transmitter can be set to stereo or mono sound.)
    - Set 830 TV - (Infrared transmission - must be line of sight to the transmitter to work.) (Incorporates increased audio intelligibility where the frequencies of the human vocal range are enhanced to make dialog stand out from background noise and and hence dialog is more distinct.) (Incorporates built in preset audio adjustment levels to adjust for different types of hearing loss.) (Volume to each ear can be adjusted independently and the transmitter can be set to stereo or mono sound.)
    - Set 830 S - (Infrared transmission - must be line of sight to the transmitter to work.) (Incorporates increased audio intelligibility where the frequencies of the human vocal range are enhanced to make dialog stand out from background noise and and hence dialog is more distinct.) (Utilizes induction loop technology to work specifically with Hearing Aids.) (Incorporates built in preset audio adjustment levels to adjust for different types of hearing loss.) (Volume to each ear can be adjusted independently and the transmitter can be set to stereo or mono sound.)
    - IS 410 - (Infrared transmission - must be line of sight to the transmitter to work). (Incorporates a compression feature that compresses background noise to allow dialog to become more distinct.)
    NOTE: On the Set 830 S and the Set 840 S the induction loop can be replaced with a set of wired headphones to allow for more wearing options. This means that there is a wire from the headphones to the wireless receiver but you are wireless from your audio source.

    - A 200 - (No wireless signal transmission) - Personal amplifier that amplifies ambient sound and makes it louder but does not receive a signal directly from an audio source via wireless transmission.

  • 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.

  • 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).
