Manhattan Analog MA35

Name: MA35
Brand: Manhattan Analog

VCF/VCA based on the Korg MS-10

12 HP Eurorack module

An internally coupled, Korg MS-10-derived VCF and VCA with a two-channel input mixer.

Features

Discrete-transistor implementation of the Korg-35 filter architecture.
Built-in two-channel audio input mixer.
Input levels overdrive past approximately 12 o'clock; lower settings are smoother and higher settings are more distorted.
Remember: the module is protected from reverse power connection, and the PCB marks ribbon-cable orientation below the power header.

Cutoff— Sets the filter cutoff frequency.
Output— Audio output from the internally coupled filter and VCA.
Mod— Sets the amount of VCA modulation.
Mode Input— CV input that switches the filter between low-pass and high-pass modes.
In 1— Sets the level of the first audio input in the built-in mixer.
In 2 Input— Second audio input to the built-in two-channel mixer.
Mod Input— Control-voltage input for VCA modulation.
In 2— Sets the level of the second audio input in the built-in mixer.
In 1 Input— First audio input to the built-in two-channel mixer.
Gain— Sets the VCA gain.
CV 2 Input— Additional control-voltage input for filter cutoff, governed by the CV 2 attenuator.
CV 1 Input— Control-voltage input for the filter cutoff frequency.
Peak— Sets the filter peak/resonance.
Gain Input— Control-voltage input for VCA gain.
CV 2— Attenuates the CV 2 control-voltage input to the filter cutoff.
Mode— Manually selects low-pass or high-pass filter operation; this selection can also be controlled by the Mode Input.
