Limiter
The signal culminates in a variable threshold, brick wall limiter. The limiter can
be bypassed completely using this switch in the OUT position. When in bypass
the unit will sum the three bands back to a full band stereo signal but then no
further processing is applied (the VCA is also bypassed). This is ideal for the
purists who would prefer to keep the signal path as simple as possible, but it
does mean the signal level will have to managed by themselves elsewhere.
Peak Level 0dB - +16dB
Sets an absolute limit to the level that the output signal will not be permitted to
exceed. This limiter is very fast acting enabling it to control any peaks without
audible distortion.The Output Gain control should be used to ensure that the
peak limiter operates only rarely if at all, if it is to be used purely for peak protection.
Alternatively, it may be deliberately driven into limiting to produce creative effects.
G.R. Meter -1, -3, -6, -10dB
VU Meter
A moving coil VU meter monitors either the level of the output or input signal.
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.
Meter Options:
VU+10dB / VU
A two-position switch adjusts the meters to show either normal output level or
VU +10dB mode, which re-scales the meter for users working at ‘hot’ output
levels. In other words, with the switch at VU +10dB the VU meter reads 0dB but
the actual level is +10dB.
Input / Output
A two-position switch adjusts the meters to show either input or output level.
In the input position the signal level is derived after the input gain, but preceeding
the split into its three bands. This always monitors the full band of the audio
signal;
In the output positon the signal level comes after the three band signal has been
summed and passed through the output gain and limiter. If any of the bands have
been muted or bypassed this is also reflected in the meter.
