manual abstract
The GC2020C is a 2-channel high-performance compressor/limiter designed for professional recording and sound reinforcement applications. The GC2020C provides a wide variety of control features for precise tailoring of compression and limiting parameters. It also features an expander gate to eliminate source noise that can be accentuated by the compression process. GC2020C compression can be used to add extra punch and a more consistent level to a final mix, and channels can be linked for stereo operation. A small amount of compression provides a more consistent signal level when recording a singer that tends to move closer to or further away from a vocal microphone. Essentially, the compressor is reducing the dynamic range. This technique can also be used with other instruments, such as acoustic guitar, bass guitar, and piano. In fact, any instrument with a wide dynamic range can be recorded more easily with a little compression applied. Creative compressor application include adding extra punch to bass, snare, and tom tom drums. GC2020C limiting can be used to protect speakers in a sound reinforcement system. Whether your applications are signal control, signal correction, or simply creative—the GC2020C is flexible enough to handle all your needs. To get the best from your GC2020C, read this manual thoroughly, and keep it in a safe place for future reference.

GC2020C Compressor/Limiter Owner’s Manual Precautions Precautions Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity—such as near radiators, stoves, in direct sunlight, etc. Avoid locations that are subject to excessive dust accumulation. Extreme vibrations can cause mechanical damage. Avoid physical shocks Strong physical shocks can damage the unit. Handle it with care. Install the unit with plenty of space for ventilation This unit should be installed in such a way as to maintain a gap of 10 cm or more between the rear of the unit and the wall. This will prevent heat build-up inside the unit and possible fire hazard. Do not open the unit, or attempt repairs or modifications yourself This product contains no user-serviceable parts. Prefer all maintenance to qualified Yamaha service personnel. Opening the unit and/or tampering with the internal circuitry will void the warranty. Make sure the power is off before making or removing connections Always turn the power OFF prior to connecting or disconnecting cables. This is important to prevent damage to the unit itself as well as other connected equipment. Handle cables carefully Always plug and unplug cables—including the AC cord—by gripping the connector, not the cord. Clean with a soft dry cloth Never use solvents such as benzine or thinner to clean the unit. Wipe it clean with a soft, dry cloth. Always use the correct power source Make sure the power source voltage specified on the rear panel matches your local AC mains supply: US & Canadian Model: 120V AC, 60 Hz General Model: 230V AC, 50 Hz UK Model: 240V AC, 50 Hz GC2020C Compressor/Limiter Owner’s Manual What’s a Compressor/Limiter?

English Compressor/Limiter Functions Compressor Generally, a compressor is used to fit a large signal into a small space. Specifically, in a situation where the dynamic range of the original audio signal is larger than the electronic reproduction equipment that is to process it can handle, a compressor can reduce the dynamic range of the signal t...
