The MDX 2600 XL offers different treatment in the same rack as follows:
Limiter / Compressor
expander / gate
Peak limit
de-esser
The inputs and outputs are on XLR or jack, it also offers an entrance and an exit for the side-chain (for each channel).
It also provides a circuit for simulating a sound "tube". In fact it is just a little digging in the upper midrange EQ to get a more "sweet". The effect is to forget as it distorts the signal ..

UTILIZATION

use is relatively simple for those who are accustomed to handling this kind of device .. One can only regret the choice made by using potentiometers Berhinger notched prohibiting any fine tuning is done ..

SOUND QUALITY

This is where it gets complicated .. In use compressor not much to say, given the price offered by Berhinger compression is pretty good if you do not exceed a ratio of 3 / 1 and / or a compression ratio of 3 / 4 dB if the Shadocks are not far ..
The peak is very limited way to stay cool (the Shadocks return for revenge).
The expander / gate is cons of good quality, but does not claim, however, to replace a true dedicated expander.
De-esser is to forget as it hurts his work, and approximate compression for all frankly unusable! Prefer him a BSS DPR 402 certe much more expensive but no action level as "de-essing" (and compression as well).

OVERALL OPINION

Purchased a few years ago for some menial, I do not regret my purchase. But do not ask him what he can not do, it obviously can not compete with a DBX 160A for compression or pure BSS DPR 402 but the price is not the same do not forget it!
To summarize the compressor does not break the bank (its main asset), but as soon as possible go to the higher speed!
