audio path color
transformer coupled compressorThe most well known audio compressor that uses a diode bridge as the gain reduction element would have to be the Neve 2254. The Kick is not a copy of the 2254 - but it is the inspiration for the design. The audio path is balanced from input to output to achieve best headroom. It includes our BE60 buffer input amps and ultra low noise Class A discrete BE41 amplifiers at the output. We have a custom "radio steel" transformer feeding into the gain reduction diode bridge between the input and output amplifiers. This configuration produces a vintage character that can best be described as tight, colourful and rich with harmonics! Included is the Buzz Audio side chain design with attack and release responses offering a wider range of feel and rhythm choices.
dynamic ratio power
Our 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.
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. Rotary 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. The bass function introduces a high pass filter to the side chain to lower compression sensitivity at low frequencies which is useful on the mix bus and the fast response hi-resolution 15 LED bar graph meter accurately displays gain reduction.
Features
- GAIN - this control adjusts the output makeup gain of the compressor.
- COMP - clockwise rotation of this control increases the amount of compression.
- ATTACK - rotary switch with 6 settings, FAST (less than 0.5mS)-5mS-10mS-15mS-25mS-50mS.
- RELEASE - rotary switch with 6 recovery time settings, 50mS-100mS-200mS-400mS-600mS and AUTO.
- LINK - two Kick compressors can be side chain linked for stereo operation.
- SOFT - adds dynamics in soft mode for times when lighter compression is desired.
- BASS - reduces compression sensitivity at low frequencies for more bass punch, approx 8dB at 100Hz.
- ENGAGE - this switch is used to engage or hardwire bypass the compressor.
