Operating
Resistor R3 provides signal to the "ring" of tip-ring-
sleeve. If you clip one of the leads on R3, you will dis-
able stereo operation and increase the power available
to the left or mono output. Another common solution is to
wire your headphones with a stereo headphone plug but
wire both ears to the left channel (the tip of the plug)
and leave the ring unconnected. This has the same ef-
fect as clipping the resistor on RemoteAmp.
Gain Adjustment
Behind the back cover of the RemoteAmp you will find a
jumper on the circuit board which allows you to adjust
the maximum amount of gain the RemoteAmp delivers.
In the factory default open position you will receive a
maximum of 25 dB gain. If the jumper is set to the op-
tional closed position, a maximum of 40 dB gain will be
delivered.
Battery
An alkaline battery is strongly recommended. The bat-
tery test indicator shows the strength of the battery
power remaining. A bright light indicates plenty of power,
a dim light reminds you to be prepared with a fresh bat-
tery. Once the LED stops responding to the test switch,
you will begin to hear signal breakup and distortion as
the battery is drained of its last breath which may mean
minutes or hours depending on the circumstances.
