QUICK SETUP PROCEDURE
Please note that the following procedure is only a guide. All audio is different, requiring numerous settings, however,
this should give a good staring point:
1) Set the compressor settings to be the same on all bands -
Threshold
fully counter-clockwise,
Gain
at 0dB,
the
Attack
in a mid position (2 or 3) and
Release
set to F(ast). The overall
Gain
control should be set to 0dB,
and the
Mix
at 0 (Wet).
2) Turn on the
Bypass
switch (bottom right) so that the input signal is heard without compression and adjust the
incoming signal until the
VU meters
rear 0dB. Set the
Bypass
switch back to Normal.
3) With the
Low X-Over Frequency
set fully counter-clockwise, and the
High X-Over Frequency
set fully clockwise,
listen to the audio and bring in the two knobs to the positions that you think the cross-over points should be set
- generally to separate the main bass and treble sounds from the mid-range. Using a combination of
Mute
and
Bypass
switches for the various bands allows the operator to monitor only the frequencies that are required and so
tune the low, mid and high frequencies.
4) Keeping an eye on the
Gain Reduction Meters
alter the
Threshold
level control for each band until the desired
compression level is achieved - a G.R. level up to -10dB is acceptable.
5) Adjust the
Gain
control of each band until 0dB is reached on the
Output VU meter
. To see only the band that
is being adjusted on the VU meter
Mute
the other two bands.
6) Set the
Attack
and
Release
settings of each band to suit the audio being compressed.
7) The
Threshold
and
Gain
of each band can be modified to achieve the desired compression, levels and tonal
balance to the overall signal.
8) At this point the
Bypass
switch can be toggled to listen to the affect that the 1973 is having on the audio.
Adjust to suit.
9) Once each band is setup correctly modify the overall
Output Gain
and
Mix
until the VU meters read 0dB
(more if in +10dB VU mode) and the desired amount of compression is heard.
Below is an example setup that could be used for a General Pop Mix, though, of course, as all music is diverse and
varied, will not be ideal elsewhere.
