1960 OPERATORS’ MANUAL

Attack:

Three switchable Attack settings are provided giving Fast,

Medium and Slow attack times. The actual attack time is
further modified by the release setting chosen.

Release:

There are four fixed Release times and a further two which

are programme dependent. Switch settings 1 through to 4
provide progressively increasing release times, while
positions 5 and 6 cause the release times to vary in a
manner which automatically adapts to the dynamics of the
incoming signal, as detailed below:-

Release Times

400 ms

(Fixed)

1 sec

(Fixed)

2 sec

(Fixed)

4 sec

(Fixed)

Automatic 400 ms to 2 sec signal dependent

Automatic 200 ms to 20 sec signal dependent

Output: (Gain)

The Output level may be amplified, or attenuated by up to

20dB to compensate for level changes caused by
compression and limiting.

VU Meter:

A moving coil VU meter monitors either the level of the

output signal (over the range -10dB to +10dB with reference
to the +4dBu operating level) or the amount of gain
reduction taking place. Because the meter has VU
characteristics, it closely reflects what is actually being
heard, though will not respond quickly enough to register
short signal peaks.

VU / GR:

Switches the meters to show either the output level (VU) or

the amount of gain reduction (GR).

Norm/Bypass
S/C Listen:

In Normal mode, the signal is passed through the
compressor. Bypass only takes the compressor out of
circuit leaving the vacuum tube warmth in the circuit path;
the output signal is taken from the signal insert return point.
S/C Listen routes the side-chain signal directly to the
output allowing the effects of any additional side-chain
processing, such as equalisation, to be monitored.
