Operating The C com opti
USING THE ENHANCER
The C com opti’s ENHANCER switch can be engaged to activate the EFR (Enhanced Frequency Recovery) cir-
cuit. By engaging the ENHANCER, the C com opti EFR
restores the high frequency content that can be lost when
high gain reduction is applied. The C com opti EFR
achieves this by adding back the high-end of the original
signal in an amount that is equal to the amount of gain
reduction.
• Follow the section above, “SETTING UP THE C
com opti” for normalizing the controls and run a
signal such as a vocal track through the C com
opti plus.
• Press the BYPASS switch to the IN position.
• Set the ATTACK control to 5 and the RELEASE
control to 0.3.
• Adjust the Ratio to 4 - 5:1.
• Press the ENHANCER switch and listen to how the high end is restored.
USING THE STEREO LINK
For stereo applications, two C com opti’s can be used in together using the rear
panel STEREO LINK connector. The STEREO LINK connector is a 1/4-inch phone
jack that provides external access to the C com opti compression detection circuit.
When using two C com opti’s in stereo applications, it’s important that the relative
balance between the left and right channels is maintained. By connecting a stan-
dard, 1/4-inch instrument cable between the STEREO LINK connector of the left
channel C com opti and the STEREO LINK connector on the right channel C com
opti, the two compressor’s detection circuits are internally summed together. The
result is, both the left and right channels signals will work together to effect the
amount compression on both the left and right channels. Now, that the two C com
opti’s are responding to the same detection signal, you should set the controls of
the left and right channels C com opti to the same positions, since each C com
opti’s THRESHOLD, ENHANCE, ATTACK, RATIO, RELEASE and OUTPUT controls are still working indepen-
dently.
