Step 7: Set the Attack and Release knobs for both channels fully counterclockwise (to their SLOW
position).
Step 8: Set the Ratio knobs for both channels to their 4 position, thus selecting moderate compression
(at a 4:1 ratio) for both channels.
Step 9: Power on the 2-1176. The purple LED above the power switch will light up.
Step 10: Unmute your speakers and begin monitoring the 2-1176 left channel output only. At the
source, raise the level of the left channel input signal until the left 2-1176 meter shows optimum
signal strength (around 0 VU, with occasional excursions into the red, but with no audible distortion).
Step 11: Now it’s time
to hear the effect of compression on your signal. Set the Meter switch for the left
channel to its leftmost (GR) position; the left channel meter will reflect the amount of gain reduction.
As you increase the amount of compression (by raising the level of the Input knob), the overall signal
will be attenuated; turn the Output knob clockwise to make up the difference. Set the Meter switch
back to its rightmost (+4) position in order to view the output level of the left channel of the 2-1176
and ensure that you are applying the correct amount of makeup gain. You can compare the
uncompressed signal with the compressed signal with the use of the BYPASS/COMP switch in the
center of the front panel. (Note that the Input and Output knobs for each channel remain active even in
BYPASS mode.)
Step 12: Experiment by selecting different Ratios, including ALL (“All-Button” mode, equivalent to
pressing in all four Ratio buttons on an 1176LN simultaneously). Note that selecting a Ratio of 1 (1:1)
results in no gain reduction, but that the “color” of the 2-1176 channel is still imparted to the signal.
(This has the same effect as setting the 2-1176 to BYPASS mode.) Also try varying the Input level and
Attack and Release times for different compression and limiting characteristics. Note that, unlike
many other devices, the 2-1176 attack and release times are faster when their associated knobs are
turned clockwise, and slower when they are turned counterclockwise. Set the left channel’s Meter
switch to GR in order to view the amount of gain reduction being applied to the signal. Note that as
you increase the amount of gain reduction (by raising the Input level and/or selecting higher ratios),
the overall signal may be attenuated. If necessary, you can make up the difference by turning the
Output knob clockwise. Return the Meter switch to its rightmost (+4) setting in order to view the final
output level. A meter reading of 0 corresponds to an output level of +4 dBm at that channel’s output.
Step 13: Repeat steps 10 - 12 above, this time routing signal to the right channel only and adjusting
the 2-1176’s right channel controls as desired. Note that, in DUAL mode, the two channels operate
completely independently of one another, giving you two discrete compressor/limiters.
Step 14: To hear the effect of the two compressors stereo linked, set the LINK/DUAL switch in the
center of the front panel to its up (LINK) position, and set the Input and Output knobs in both channels
identically. Note that, in Link mode, the left channel Attack and Release knobs act as master controls
for both channels.
