CARVIN CG200 Instructions

CARVIN ENGINEERING DATA
Congratulations on your purchase of the CARVIN CG200 two
channel Optical Compressor/Gate. The CG200 was designed with
the professional in mind. Your unit has been engineered and
assembled in the U.S.A., using only high quality electronic
components and uncompromising workmanship. The CG200 was
designed around hand matched analog optoisolators. Unlike many
compressor/gates which use higher noise VCA's, the CG200 is
based on classic optical compressors from the 60's that had that
warmth and softness that cannot be recreated with VCA's.
Optoisolators are also known for their extremely low distortion.

CG200 Optical Compressor/Gate INSTRUCTIONS
CONNECTING UP
The CG200 can be used in various applications that require different
configuration within a sound system. Fig. 1 shows the CG200
connected between the stereo output of a mixer and the inputs of a
power amp. This is best for compressing or gating an entire main
mix of program material. Fig. 2 depicts a channel insert
connection. This is done with a TRS (tip send, ring return) Y-cable.
The signal is sent out of the channel, compressed/gated and
returned into the channel. This is a typical set-up on most vocal or
drum microphone channels. Fig. 3 depicts a mic channel direct out
to the SIDE CHAIN INPUT. The mic signal triggers the
compressor/gate .

Connect the CG200 between the CD
player and the mixer. Use a
standard unbalanced 1/4" cable and
"half insert" into the INSERT jack on
the mixer and connect the other end
to the SIDE CHAIN INPUT on the
CG200. Connect a vocal mic to the
same channel as the insert cable on
the mixer. The CG200 will
compress the CD audio whenever
someone speaks into the mic.
