audio path color
The most well known audio compressor that uses a diode bridge as the gain reduction element would have to be the Neve 2254. This is not a copy of that unit - but it is the inspiration for the DBC-20 design. The audio path features our Class A discrete BE41 amplifiers in a balanced configuration throughout, and for extra colour, we have a custom "radio steel" laminated transformer coupling into the diode bridge. This combination produces a vintage character that can best be described as tight, colourful and rich with harmonics!
dynamic ratio power
The unique side chain design re-creates the style of compressors from the 60's (think Fairchild) whereby the compression ratio is progressively increased with deepening gain reduction. So as the input signal increases past threshold, the ratio will vary from 1:1 right up to 15:1. This feature allows for the control of very dynamic signals (such as vocals) in a seamless fashion and is also a very desirable characteristic when used on complex percussive material such as the drum buss and drum loops. On the mix buss the DBC-20 adds perfect analog colour to "in the box" mixes.
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 are provided for the amount of compression and the output gain control. The compressor can be switched to a Soft mode whereby dynamic peaks are partially retained. Another switch introduces a high pass filter to the side chain to lower compression sensitivity at low frequencies which is useful on the mix bus. The large knobs with pointers allow for accurate resetting of the compressor and the fast response 15 LED bar graph meter accurately displays gain reduction.
