ADA Hearing Assist System
The Listen®LT-800 Stationary Transmitter in the audio rack allows individuals to
experience every word at an event. This system is designed to broadcast the audio
signal throughout the facility. It is capable of transmitting to multiple receiver types
and its adjustable receivers allow each user to have full volume control.
The Listen LT-4200 Portable FM Receiver (Figure 10) provides users with the choice of
57 channels and accessory options ideal for a wide range of applications. The receivers
are digitally tuned so transmission will not drift, assurance that when you select a
channel it stays on the channel.
Wireless Personal Stereo Monitor System
The Shure®PSM®900 Wireless in-ear monitor system is used for on-eld/on-stage talent.
The system includes a transmitter in the audio rack and a receiver (Figure 11) worn by the
performer that allows for personal adjustment of mix and volume and compensates for
delay from the sound system.
Sound travels at 1120' (341 m) per second. This produces a noticeable delay as one moves
away from the speaker. Even experienced performers have trouble adjusting to this delay.
A wireless in-ear monitor system provides a real-time signal to the talent and blocks the
sound delay from their ears.
Note: If more receivers are required and the transmitter is already installed,
additional receiver packs and headphones are available to purchase.

3.7 Microphone Best Practices
• Keep handheld microphones 4-6 inches (102-152 mm) from the mouth (about the width of a hand).
“P-pops” are loud sounds created by the release of breath when saying letters like “p” or “b”. To
avoid P-pops, keep handheld microphones below the mouth, angled toward the nose at a 45° angle.
Do not point the front of the microphone straight at the mouth.
• Position headset microphones as close to the mouth as comfortable.
• The referee bodypack kit includes both headset and lapel microphones. In general it is recommended
to use the headset mic for best results. If the lapel mic is desired, clip it onto a lapel, as close to the
center of the chest as possible.
• The softer or louder the speaker’s voice, move the microphone closer or further away, respectively.
• Never hit or intentionally blow into a microphone as it could quite easily be damaged.
3.8 Personal Monitor System Operation
Basic instructions are described below and shown in Figure 26. For more information, refer to the Shure®
PSM®900 Personal Wireless Monitor System User Guide.
1. Flip the transmitter POWER switch to ON if it is not already on; ensure the RF switch to the left of it
is OFF at this time.
2. Power on the handheld receiver using the volume knob.
3. Attach the antenna and earphones to the top of the handheld receiver.
4. Flip open the battery cover to expose the control buttons. Press SCAN and the display will show
“SYNC NOW”.
Note: Insert new or fully-charged batteries prior to each use, and always have spares on hand.
5. Hold the bodypack up to the transmitter with the sync IR windows facing each other, and press the
SYNC button on the transmitter. The display will show “SYNC SUCCESS” when nished.
6. Flip the transmitter RF switch to ON. The blue LED on the receiver should illuminate to indicate that
it is detecting the transmitter.
