“33” to “99” (inclusive) is the same as channel 32. NOTE 2: If the AT900-32 and AR900-32 will be used along with an Applied Wireless video transmitter and receiver (models VT900-3 and VR900-3), the channel for the audio units must be at least 9MHz above or below the channel of the video units, to prevent interference between the RF signals. -
Page 9: Audio Level
IMPORTANT! Properly setting the transmitter’s modulation level is CRITICAL to satisfactory operation of the transmitter, and receiver. If the level is set too low, the receiver will likely be plagued with objectionable background noise (hiss). If the level is set too high, distorted audio and/or interference on adjacent channels is likely to result. - Page 10 (while the display is indicating the equalization profile) will advance to the next profile. The 2-digit CHANNEL indicator will automatically revert to displaying the receiver’s current channel when the button has not been pressed for two to three seconds. Applied Wireless, Inc.

Page 13: Internal Settings
Internal Settings The AT900-32 transmitter and the AR900-32 receiver each have internal jumpers and/or switches (on their respective printed circuit boards) that are preset at the factory to provide the proper configuration for most applications. The following sections describe these settings, and provide guidelines for when it may be necessary or desirable to modify them. - Page 14 ) setting, configuring the receiver for maximum sensitivity. This is the appropriate setting for most applications (to allow for maximum reception range). However, if multiple AT900-32 transmitters are to be used in a common area (so as to broadcast multiple audio...
- Page 15 Noise Reduction (Transmitter and Receiver) The transmitter and receiver are each equipped with active noise reduction circuits that minimize objectionable background noise (or “hiss”) which might otherwise be noticeable during periods of silence, such as the pause between tracks on a CD. These circuits are normally enabled (factory default).
