Functions
Clip LED
The LEd lights up orange when the output signal distortion on the
corresponding channel rises above 1%, which indicates that the "clip-
ping" has occurred because the signal level is too high.
3. Do not short connect the ground wire and
the input signal ground wire of the cable.
this will form a ground loop and couse the
oscillations.
4. Tampering of modifying the circuit without
authorization will be dangerous and will
make all services provided by agents lose
efficacy.
5. Do not use the unit when the yellow clip LED
is continued flashing.

it will send a clipping signal to the unit. The
unit will accurately reproduce such signals,
which may cause speaker damage.

ance is lower than the nominal. Because of
the output protecton of the unit, this config-
uration will result to the premature cliping
