Reference-Class 4-Channel Expander/Gate/Compressor/Peak Limiter with Dynamic Enhancer and Low Contour Filter
Product Features
MULTICOM PRO-XL MDX4600 V2
The reference-class MDX4600 is a marvelous 4-channel Expander/Gate/Compressor/Peak Limiter that is ideal for: compressing mono/stereo signals and providing virtually inaudible noise suppression, without loss of high frequencies; increasing vocal presence and energy; and limiting, or smoothing out extremely-high signal peaks. Additionally, the MDX4600 features an integrated Dynamic Enhancer and Low-Contour filter to provide the ultimate in signal enrichment. Put simply, the MDX4600 can do amazing things for your vocals or instruments – providing virtually everything you need for studio-quality dynamics processing!
Audio Dynamics Toolkit
Here are just a few of the MDX4600�s outstanding capabilities:
- Switchable IKA (Interactive Knee Adaptation) � provides program-adaptive compression, combining all the advantages of both hard and soft-knee compression
- IRC (Interactive Ratio Control) Expander/Gate � ideal solution for noise floor reduction vs. applying notch filters and various equalizers for virtually inaudible noise suppression
- Enhancer � lets you emphasize the Bass, Midrange and Hi output at selectable frequencies for maximum punch, clarity and detail � without raising overall volume
- IGC (Interactive Gain Control) Peak Limiter � combines clipper and program limiter for reliable, inaudible protection against signal peaks
- Stereo Couple � links 1/2 and 3/4 channels, allowing dials and switches of Channels 1 and 3 to provide dynamics control over Channels 2 and 4, respectively (true stereo processing)
Options Abound
The MDX4600 features amazingly-accurate, 8-segment LED meters for In/Out Level and Gain Reduction, switchable +4 dBu or -10 dBV operating level, Side Chain I/O, and servo-balanced XLR and 1/4" Inputs and Outputs. Best of all, the MULTICOM PRO-XL MDX4600 takes up just a single rackspace.
Sound Value
The incredible MDX4600 is the ideal solution for becoming the master of your dynamics. With its flexible routing options, all the I/O you could ask for, plus a host of other professional features – the MDX4600 is an exceptional tool for your live shows – and an absolute “must-have” for your studio!
