Drawmer DL441 Quad Auto Comp/Limiter - Manual (Page 8)

DL441 OPERATORS’ MANUAL 6
Bypass:
This switch will disable the functioning of the Compressor
section and the Peak Limiter. If operating in Stereo Linked
mode, both linked channels will be bypassed simultaneously.
The DL441 Bypass is a 'hard bypass' which directly links the
input sockets to the output sockets whenever Bypass is active.
The adjacent red LED indicates the Bypass status.
Gain Reduction Meter:
An eight segment LED bargraph meter continuously monitors the
gain reduction applied by the compressor/limiter over the range
0 to 30dB.
Output Level Meter:
This is a 5-segment LED bargraph level meter that monitors the
level of the output signal over the range -10dB to +10dB with
reference to the selected (-10dBu or +4dBu) operating level.
Peak Limiter
Level:
This control 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.
If the output signal is so high as to cause the limiter to operate
for more than 20mS, the system gain is automatically reduced to
bring the signal back within range. The system gain is then
returned to normal over a period of approximately one second.
The compressor Gain control should be used to ensure that the
peak limiter operates only rarely if at all if the limiter is to be
used purely for peak protection. Alternatively, the unit may be
deliberately driven into limiting to produce creative effects.
Linking
Stereo Link:
These two switches configure channels 1,2 or 3,4 for stereo
operation where the left hand channel’s controls act as masters
for both slave audio channels.
The same degree of gain reduction is applied to both audio
channels to prevent image shifting which would otherwise occur
whenever the left and right signal dynamics varied from each
other by any significant degree.
