IGS Multicore Multiband Compressor

Three bands of classic analog VCA compression provide an infinite field of possibilities to shape the sound.

The Multicore is very versatile tool in your studio. Three bands of classic analog VCA compression provide an infinite field of possibilities to shape the sound. The device can be used as a mix bus compressor or for mastering purposes. Due to separate control of the audio bands it can be applied, for example on vocals to control sibilants without affecting on dynamics of the low band.

Features

The core of device is based on a three band, adjustable active crossover. It splits audio signal into three bands (Low, Mid and High) with a gentle slope of 6dB/oct. That allows you to control the dynamics of each band in a very musical way without phase problems. Each of the bands has its own compressor module equipped with standard controls: Threshold, Ratio, Attack Release and Gain. A very useful feature is Mute/ON/Bypass switch on each band. The “Muted” option allows you to switch off the bands. If you mute two of them, you can hear only one band and monitor its audio content and bandwidth.

The Multicore has transformer balanced inputs and outputs (Carnhill UK). The signal path is made with THT (Through-Hole Technology) components only. Passive components are matched between channels to provide best L/R correlation. High quality selected components ensure stability of parameters and superior sound. Low noise, negligible crosstalk and high headroom makes the device can be used in the most demanding professional audio applications.
