The Behringer Multicom Pro-XL MDX4600 4 Channel Compressor/Limiter and Peak Limiter provides four channels of Interactive Knee Adaptation (IKA) compression/limiting, housed in a single rack space chassis. A peak limiter on all channels helps prevent clipping of the audio source. Each compressor features program dependent attack and release times with a switchable side-chain filter to help with bass dominated compression. Channels 1/2 and 3/4 can be switched as independent pairs for stereo operation and accurate metering and professional connections provide extensive processing power.
