All filter and equaliser functions of the PE232MKII are switchable
IN and OUT of the signal paths. The complete unit can be
bypassed by switching it off. The fail safe relays will react as if
there were a mains failure and will link the input of each channel to
its corresponding output.
The PE232MKII has electronically balanced inputs and balanced,
floating output stages. Each output circuit actually simulate a
transformer with a 10KOhm impedance to ground for each leg.
Both the input and output circuits are factory adjusted for optimum
balance at low and high frequencies. This results in increased
interference immunity of the unit.
The overall gain of each channel of the PE232MKII is variable
from -• to +6 dB with the front panel level control. All potential
overload points of each channel are continuously monitored by an
extremely fast “peak” overload detector, followed by a “peak-
stretching” circuit for clear indication of overload conditions. The
detector thresholds are chosen for approximately 2 dB headroom
when the overload led illuminates, giving the user the ability to
