Front Panel
_____________________________________________________________
(6) Meter - A standard VU meter that displays either the amount of gain reduction, or output level,
depending upon the setting of the Meter Function switch. ( see #7 below) Occasionally, the meter
may require calibration. ( see page 25 for instructions for calibrating the 1176LN meter)
(7) Meter Function – These four buttons power the unit on (or off) and determine what the 1176LN’s
front panel VU meter displays: either the amount of gain reduction (GR), or the compressor’s output
level (+8 or +4). When “+8” is selected, a meter reading of 0 corresponds to a level of +8 dBm at the
rear panel outputs. When “+4” is selected, a meter reading of 0 corresponds to a level of +4 dBm at
the rear panel outputs. ( see #2 and #4 on the following page) Depressing the OFF position has the
effect of powering off the 1176LN.
In order to obtain a specific amount of limiting or compression on the 1176LN, begin by
setting both the Input and Output knob to approximately 24 (their twelve o’clock positions)
for unity gain. Set the Ratio as desired, then set the Attack and Release controls to
approximately “4” (their 12 o’clock positions) so that some gain reduction is enabled.
Depress the Meter GR button so that the meter shows the amount of gain reduction, then
slowly turn the Input control up until the desired amount of gain reduction is achieved.
Finally, adjust the Attack and Release times until they are suitable for the program
material and make up any gain necessary by raising the Output knob (depress the Meter
+4 or +8 buttons to have the meter display the final output level).
