The DBC-M is a Mastering version of the popular Buzz Audio DBC-20 diode bridge compressor and offers fully switched control for repeatable settings. The diode bridge gain reduction element coupled with their innovative side chain design delivers a vintage vibe like no other. The DBC-M audio path uses our Class A discrete amplifier designs in a balanced configuration from input to output with a radio steel laminated transformer to couple into the diode bridge element. This overall combination produces a desirable compression character that can best be described as tight, colourful and rich with harmonics.

dynamic ratio power

In the style of compressors from the 60's, the DBC-M incorporates a automatic ratio whereby the compression ratio is progressively increased with deepening gain reduction. This feature allows for the control of very dynamic signals in a seamless fashion and is also a very desirable characteristic when used on complex percussive material.

operational ease

This compressor is easy to get happening with six switched attack and release times covering a wide range, including an interesting auto release mode. Big knobs with 24 position stepped Elma controls are provided for the amount of compression and the output gain. The compressor can be switched to a Soft mode whereby dynamic peaks are partially retained and another switch introduces a high pass filter to the side chain to lower compression sensitivity at low frequencies. The attractive "point source" red LED bar graph meter accurately displays gain reduction and the gloss finish knobs adds to the vintage feel of the DBC-M.
