Front Panel
1 Attenuator
There are 2 level controls on all IS models. Each control is labelled for the
channel which it controls. 0dB indicates minimum attenuation.
2 Clip Indicator
This LED displays the status of the output stage and displays two levels of
operation.
These levels are:
Below clip level (unlit)
Clipping & above (red)
The LED will change to red once the output exceeds the clipping point of
the amplifier’s output stage. The threshold is referred to the amplifier supply
rails and alters with changes in the mains supply, changes in the load and
duty cycle fluctuations.
The attack and decay time (ballistics) of the status circuit are those of a
Peak Programme Meter (P.P.M.)
