Operating The S•com 4
Whether you are an experienced audio engineer, just starting out, or you just want to experiment, follow the steps
below to get going. Further sections in this manual will cover basic dynamics and the associated parameters, sys-
tem set-ups and applications for using dynamics processing in recording and live sound applications.
SETTING UP THE S•com 4
• Connect one set of inputs and outputs to the Channel 1 connectors on the rear panel.
• Set the controls to the following positions:
EXPANDER/GATE TRIGGER – OFF
GATE SWITCH – OUT
FAST RELEASE – OUT
COMPRESSOR THRESHOLD – +20dBu (fully clockwise)
RATIO – 1:1
ENHANCER - OUT
METER SWITCH – IN
OUTPUT LEVEL – O dBu
STEREO LINK SWITCH – OUT

In this configuration, the S•com 4 is simply passing audio at unity gain with no dynamics processing. It is a good
idea to check your gain structure at this point. Use the Input/Output meter to match the level.
• Send a signal to the S•com 4’s inputs and outputs.
• Press the METER switch to see that the input and output levels are matched.
COMPRESSING A SIGNAL
S•com 4's Compressor section can be used for a variety of gain management tasks including printing signals to a
multi-track recorder, as a mix-down effect, mastering, and for increasing the loudness of a live PA system. To
begin compressing your signal, follow the steps below:
• Follow the section above, “SETTING UP THE S•com 4” for normalizing the controls.
• Press the In/Out switch (located between Channels 1 and 2) to the IN position.
• Adjust the Ratio to 2:1.
