A dual channel, single rack space dynamics processor designed to control signal levels in a variety of applications. Each channel combines an expander/gate, compressor/ limiter, and enhancer to reduce noise, increase loudness and recover lost frequencies. The expander/ gate function features a variable threshold level & switch for fast or slow release times. There is a key input & key listen for external triggering or EQ. The enhancer section is fully adjustable and facilitates the recovery of high frequencies.
