Stereo Operation and Calibration
With the use of an external 1176 Stereo Adapter (1176SA), available from Universal Audio, two
1176LNs can be connected for stereo operation.
Use the following procedure to calibrate the 1176SA stereo adapter:
1. Remove the signals from both 1176LN units.
2. Disable gain reduction on each 1176LN by setting both Attack controls fully counterclockwise.
3. Using two cables with RCA connectors on both ends, connect the 1176-SA to both 1176LNs.
4. Depress the Meter GR pushbutton.
5. Adjust the potentiometer on the 1176-SA until both meters read 0dB. If it is not possible to
zero both meters, reverse the stereo interconnect cables and repeat the preceding step.
 When used in stereo operation, the Attack and Release controls on the two 1176LNs will
interact so that changing the Attack or Release times on either device changes that of
both devices. Also, when connected in a stereo configuration, the fastest attack time is
doubled (that is, it becomes 40 microseconds instead of 20 microseconds.
 During normal stereo operation, both 1176LNs should be set to the same Ratios as well as
similar Input and Output levels.
