Manley ELECTRO-OPTICAL LIMITER - 1994 - 1997 MANELOP020-318 - Manual (Page 7)

FRONT PANEL
A REDUCTION. Adjusts the amound of limitng in the that channel. This could also be called
Threshold. Turning this clockwise introduces limiting.
B IN / BYPASS. Audio still flows through the tubes in BYPASS but at Unity Gain. Switching
to IN provides the Limiting controls and functions. Use this switch to verify that the limiting
is not messing up the original sound but enhancing it or at least levelling the volume.
C GAIN Adjusts the gain of that audio channel. Unity gain is about the seventh marking or 1
o'clock. Limiting usually requires some additional "make-up" Gain to compare IN / BYPASS.
The Gain control can also be used as the level to tape.
D STEREO LINK / NORMAL Switching the toggle UP provides the STEREO LINK. It is
used on stereo tracks so that when either channel is called to limit, both channels reduce the
same amount at the same time. This prevents image shifts and an instrument should stay
where you panned them. Limiting individual sounds is usually done with the switch down
where each side is independent of the other.
E METER Shows the amound of gain reduction in dB from the 0 dB mark. Functions as a
high quality VU meter when the switch is set to METER OUTPUT. Note that VU meters and
PEAK meters rarely agree and that digital recorders use peak meters - Rely on those for clean
recording. VU meters are standard with analog machines and big consoles because they
correspond well with perceived loudness.
F METER SELECT Switch to REDUCTION to see the amount of limiting in dB. The wider
and quicker the reduction meter swings the more likely the limiting will be audible.
Switch to OUTPUT to show the output level as a conventional VU meter.
G POWER SWITCH Switch up to turn the unit ON. Both meters will illuminate when the
power is on.
H STEREO ADJUST Active only in LINK mode. It offers a quick and easy control to adjust
the LEFT / RIGHT BALANCE by few dB. One side increases by 1 dB while the other side
drops by 4 dB. It operates on the input signal before everything.
