RemoteAmp Headphone / Earpiece Amplifier User Guide JK Audio
Description 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 excessive signals into your earpiece.
Operating Resistor R3 provides signal to the "ring" of tip-ringsleeve. If you clip one of the leads on R3, you will disable 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 effect as clipping the resistor on RemoteAmp.
