Guided Tour - Wireless EarAmp® Receiver
7
10: Headphone jack - Connect the supplied stereo earbuds (or third-party earpieces—see Appendix D
on page 13 in this manual for more information) to this standard 1/8" (3.5 mm) mini-phone jack in order to
monitor the signal being output by the Wireless EarAmp®. The level of the headphone signal is set by
adjusting the Volume control (see #12 below). Maximum output is 200 mW @ 32 ohms.
11: Loudness switch - At normal listening levels, this should be left off (with the switch to the left).
When using the Wireless EarAmp® at low signal levels, turning this on (placing the switch on the right)
will improve legibility by boosting both bass and treble frequencies.
12: Volume control - Use this to set the level of the signal in connected earbuds.
13: Battery LED - This LED lights red when battery level is low and the battery needs to be replaced.
14: TX LED - This LED lights steadily green whenever the Wireless EarAmp® receiver is receiving RF
signal from the transmitter and flashes when the receiver is being reprogrammed to operate at a different
radio frequency. Both the receiver and transmitter must be set to the same RF frequency for correct
operation. See the “Setting Up and Using The Wireless EarAmp®” section on page 8 of this manual for
information on how to program the receiver to operate at the selected transmitter frequency.
15: Balance control - Adjusts the relative levels of the two signals being received by the Wireless
EarAmp®. When set at the center 12 o’clock position, both signals are presented to connected earbuds
at equal strength. When the Wireless EarAmp® is operating in “Stereo” mode (that is, when the
2 CH/Stereo switch [see #6 on the previous page] is set to “Stereo,”) turning the balance control
clockwise increases the relative amount of right channel signal (that is, the signal in your right ear) and
turning it counterclockwise increases the relative amount of left channel signal (that is, the signal in your
left ear). When the Wireless EarAmp® is operating in “2 CH” mode (that is, when the 2 CH/Stereo switch
[see #6 on the previous page] is set to “2 CH,”) both channels are internally mixed to mono and routed to
both earbuds. In 2 CH mode, turning the balance control clockwise increases the relative amount of right
channel signal (though it will be heard in both ears) and turning it counterclockwise increases the relative
amount of left channel signal (again, heard in both ears). See Appendix C on page 12 in this manual for
more information
16: Belt clip - Use this to clip the Wireless EarAmp® receiver to your belt for convenient operation.
