Input
The input XLR accepts line level signals from your mixer,
distribution amplifier or phone line hybrid. The balanced
input XLR is wired:
Pin
1 Ground
Pin 2 Signal +
Pin 3 Signal -
This is a transformer balanced input. If you are using an
unbalanced source, you must connect your signal lead to
pin 2 and then connect your ground to pins 1 and 3. Do
not connect a powered input to this device.
Output
The 1/8” earpiece jack is current limited to prevent exces-
sive signals into your earpiece. This mono jack will power
earpieces with an impedance of 150 ohms or greater. If
you would like to use light-weight stereo headphones that
are typically 8 to 36 ohms, wired with a 1/8" stereo jack,
you will need to use an adapter to plug into the 1/4" stereo
headphone jack. Or you can solder a jumper wire across
the top of the 150 ohm resistor, R2.
The 1/4” headphone jack is wired for either a stereo or
mono plug. If a stereo headphone plug is used, you will
hear signal in both the left and right ears.
A 1/4" mono plug can also be used without any problem,
however, if you plan to always use a 1/4" mono plug, you
might consider a simple modification to the RemoteAmp.
