Additional functions
1. Clipping LED
Normally the
Clipping LED
is off and only
lights up if one of the
Line
or
Highlevel Inputs
is overdriven.
On (
red
): One of the analog signal inputs is
overdriven. Reduce the input sen-
sitivity using the three gain controls
until the LED goes out. How to
reduce the input sensitivity is de-
scribed on page 21 point 8.
Note:
The LED has no function when using
one of the digital inputs.
2. Status LED
The
Status LED
indicates the operating mode
of the amplifier and of its memory.
Green:
Amplifier is ready for operation.
Orange:
Power Save Mode is active.
Red:
Protection Mode is active. This may
have different root causes. The HELIX
P SIX DSP ULTIMATE is equipped with pro-
tection circuits against over- and undervolt-
age as well as overheating. Please check for
connecting failures such as short-circuits or
other wrong connections. If the amplifier is
overheated the internal temperature protec-
