the Power/data/audio LED lights when
the selected input audio signal is > the
reference level and is unlit when the signal
is below the reference level. Adjust the
gain until the LED blinks frequently. If the

blinks off, the level is too high. If the LED
is almost always off, but occasionally
blinks on occasionally, the level is too low.
