DISC 4ms VCA Matrix (26HP)

Full Description

4x4 Modulation Matrix

The 4ms VCA Matrix provides you with a playable 4x4 matrix consisting of 16 VCAs, which utilise high-grade SSM chips for optimal performance. The VCA Matrix module provides full range bandwidth, ranging from 0Hz – 20kHz for all control and signal inputs. This allows for AM and other versatile effects. The matrix includes 4 CV and audio inputs complete with 4 outputs which are buffered and DC-coupled. The playable surface features 16 latching Mute LED buttons, with each button giving you the ability to mute each VCA individually. The Mute button will disconnect the control jack and level knob, while providing full attenuating of the VCA.

Versatile Applications

The Matrix is ideal for a wide range of applications from sequencing and mixing to acting as a splitter or dynamic signal router and even a limited waveshaper. Its versatile connectivity and streamline design means you can make changes on the fly and experiment to the max. 16 controls jacks are included for full VCA level control as well as 16 level knobs attenuating the incoming Control signals. The level knobs on the matrix double up as manual level controls when there isn’t anything plugged into the Control jack. One of the most prominent features on the VCA Matrix Module is the Soft Limit effect which is incorporated to prevent clipping of the signals. Whilst minimising clipping, it also responds to higher control voltages, providing added punch and wider pulses.

Design & Connectivity

As a Eurorack module, the 4ms VCA Matrix is ideal as a keystone in any modular setup, with its robust design ideal for a range of uses. It can also be expanded by connecting VCA Matrices, forming a larger matrix by using header on the rear. You can also expand your control by using the 16-pin header on the rear of the PVC. This allows you to control all the VCAs from an external device, ideal for patch sequencing, preset patterns and more. The LED button brightness displays the attenuation amount, whilst controlling the CV signal. The attenuation and gain range is extended for optimal flexibility, providing a boost of up to +20db by adjusting the trimpot.

Features

• 4 CV/audio inputs and 4 outputs (buffered and dc-coupled)
• Full range (0Hz - 20kHz) for both Control and Signal inputs, allows for AM effects, etc.
• 16 VCA's using high quality SSM chips
• Attenuation/gain range from -100dB (mute) to 0dB (unity). Up to +20dB boost with trimpot adjustment.
• Playable surface with 16 latching Mute LED buttons, used to mute each VCA individually (Mute button disconnects Control jack and Level knob, and fully attenuates the VCA)
• LED button brightness indicates amount of attenuation and Control CV signal
• 16 Control jacks for VCA level control
• 16 Level knobs attenuate the incoming Control signals. The Level knobs act as manual level controls when nothing is plugged into the Control jack
• Exponential VCA response in low control voltage range, pseudo-log response in higher voltage range.
• "Soft Limit" effect limits gain to prevent clipping, while still responding to higher Control voltages with more "punch" and wider pulses
• Matrix Expandability: VCA Matrices can be connected to form a larger matrix using headers on the back (4x8, 8x8, 12x4, etc)
• Control Expandability: 16-pin header on back side of PCB allows an external device to control all VCAs: e.g. patch recall, patch sequencing, preset patterns such as quadrature panning, etc.
• Suitable as a 4x4 mixer, splitter, dynamic signal router, limited waveshaper, etc.
