Setting Up and Using The Wireless EarAmp®

8b. In the receiver, turn the Program switch off, then on (towards the “up” arrow) and then, within ten
seconds, press and hold the transmitter’s front-panel Program button for at least three seconds in order
to program the receiver; when correctly programmed, the TX LED on top of the receiver will flash (see
Appendix A on page 10 in this manual for more details). Note that the Program switch must always be
on (toward the “up” arrow) for correct operation of the receiver.
9. When first setting up the Wireless EarAmp® system in a new environment, it’s always a good idea to
do a walkaround while experimenting with different frequency settings, observing the receiver’s TX LED
as you do so. If the light fails to light steadily as you move through the area that needs to be covered ,
the receiver may be receiving interference and the selected frequency or Group/Channel is probably
unsuitable for use. Always pick the Group that has the greatest number of clear Channels and the
Channel providing the strongest signal. The basic rule of thumb for successful wireless installations is to
always try to minimize the distance between transmitter and receiver as much as possible (though not
less than 10 feet) and also to try to maintain “line of sight” between the two (so that the person using the
receiver can see the transmitter antenna). You may also be able to improve RF reception by relocating
the transmitter or repositioning antennas.
10. Once you’ve settled on the radio frequency you want to use, it’s time to set the audio levels. Turn on
your mixer and set the level of the signal you’re sending to the transmitter to unity gain (0 vu). Then
slowly raise the transmitter’s front-panel Input Level control while observing the level meters. For best
signal-to-noise ratio, adjust the Input Level control so that the yellow “0” segment lights frequently, with
the red “+6” segment lighting only infrequently during the very highest signal peaks. If you have signal
connected to the Aux inputs, use a screwdriver to adjust the rear-panel Aux Input control. If you are
sending very hot signal to the EarAmp® transmitter, you may need to set either the Main and/or Aux
Attenuator switch to “-15 dB.” To monitor the signal arriving at the transmitter, either connect a set of
headphones to either headphone jack and slowly raise the Headphone Level control or connect the
rear-panel Daisy-Chain outputs to an amp and speakers (or a pair of self-powered speakers). If you
hear distortion, back the Input Level control off slightly.
11. Set the receiver’s 2 CH/Stereo mode switch as desired. In Stereo mode, the two incoming signals
are routed to the left and right earbuds, respectively. In 2 CH mode, the two incoming signals are inter-
nally mixed to mono and both signals are routed to both earbuds. If the signal to be monitored is mono,
set the 2 CH / Stereo switch to the up, “2 CH” position. See Appendix C on page 12 in this manual for
more information about the use of 2 CH mode.
12. Start by setting the receiver’s Balance control (see #15 on page 7) to its center detented position.
and by turning the Loudness switch (see #11 on page 7) off.
13. Connect the supplied earbuds (or third-party earpiece—see Appendix D on page 13) to the
receiver’s headphone jack (see #10 on page 7) and place them in your ears.
14. Finally, while playing or singing at a normal performance level, slowly turn up the receiver’s volume
control until you achieve the desired level. The EarAmp® receiver should always be used at as low a
volume as possible. If you hear ringing in your ears, turn down the volume control and operate it
at a lower level!
15. Adjust the Balance control as needed in order to get the best blend of the incoming signals. If
necessary, use the supplied screwdriver to adjust the Limiter Level, Bass and Treble trimpots (see #3, 4
and 5 on page 6) in order to optimize the sound you’re hearing. If you’re operating at low signal levels,
turning the loudness control on will help improve legibility.
16. Close the battery door and clip the receiver to your belt.
