Mackie Quad Comp/Gate 
Four channel digital compressor and gate

The Mackie Quad Comp/Gate is a four-channel rackmount digital compressor/gate. Its compression/limiting and gating/expansion algorithms provide a very wide range of high-quality, instantly usable settings. With 99 user definable snapshots for calling up, the Quad Comp/Gate makes it much easier to get consistently fast, great-sounding mixes versus analog compressor/gates.

The QUAD Comp/Gate offers more parameters with wider ranges than most stand alone analog processors. Use the compressor for compression or limiting; it also provides threshold, ratio, attack, release, make-up gain, soft knee curve, and auto attack and release. The gate can be used as a noise gate or expander with threshold, ratio, attack, release, hold time, and a range control.

The Quad Comp/Gate's built-in Key Filtering function provides independent gating and compression detection, based on an adjustable triggering frequency, and features a convenient Key Listen - so you can easily dial-in and monitor the specific range of frequencies while you're in the mix. A Side Chain input allows for triggering the compression/gating using external signals. And the Quad Comp/Gate's "Auto" feature senses input transients to automatically adjust attack and release times - eliminating the "pumping" effect associated with compression triggering.

The front panel is intuitively laid out with ultrabright 12-segment metering, multicolor backlit buttons and nine backlit push-button knobs with LED collars to indicate settings from a mile away. You simply press the channel(s) you wish to process and adjust the knobs accordingly. Channels can be operated independently or stereo-linked with a single button press, making global FOH limiting adjustments fast and convenient. For maximum flexibility, the Quad Comp/Gate's rear panel includes both 1/4" TRS and XLR connections, TRS Side Chain send and return, and a "Planet Earth" power supply, which operates on voltages between 100 and 240v.
