M 502 D

Dual Voltage Controlled Amplifier

The DUAL VCA MODULE features each two modulation inputs, 

switchable linear/exponential mode, switchable AC/DC mode, 

single, mix and ringmodulator outputs.

M 502 S

Simple Dual Voltage
Controlled Amplifier

The  502s SIMPLE DUAL VCA MODULE module combines two separate voltage controlled amplifier circuits each with its own signal input and signal output plus modulation input.

The module has a continuous linear/exponential controller and switchable AC/DC mode (audio signals/control voltages).

The module can act as two independent mono or one stereo VCA.

M 525

Quad Reversible Attenuators

The QUAD REVERSIBLE ATTENUATOR module features four active bipolar attenuators for audio signals and control voltages. 

„0“-position = no output signal present 

“+10” position = output signal equals input signal (unity gain) 

“-10” Position = output signal equals input signal (unity gain), but inverted 

The four input jacks are “chained“, input 1 is internally connected to +10 volts if nothing ist patched.  So the module doubles as single to quad variable voltage source.

M 525M CP

Attenuator/Mixer

The M 525M ATTENUATOR/MIXER combines the functionality of the 525 Reversible Attenuator und the 526 Reversible Mixer: Four input channels with mute switches and LEDs, doubling as separate attenuators. 

Master outputs with inverting and non-inverting output jacks and master level knob.

M 526

Reversible Mixer

The REVERSIBLE MIXER is an active bipolar three channel mixer for audio signals and control voltages with master level control and both inverting and non inverting outputs. 

In addition each channel has a dedicated on/off (‘mute‘) switch with its own status LED. 

„0“-position = no output signal present 

„+10” position = output signal equals input signal (unity gain) 

“-10” position = output signal equals input signal (unity gain), but inverted.

M 543 CP

Stereo Output Mixer

The M 543 CP OUTPUT MODULE is a 4-channel output mixer with voltage controlled volume and panorama per channel.

M 543  v2

Stereo Output Mixer

The M 543 v2 OUTPUT MIXER is a 4-channel output mixer with voltage controlled volume and panorama per channel.

Ist has two vintage style VU-meters, A-440 tuning aid,

phone outputs, muting switches per input channel and for the master outputs. The Master outputs are now balanced

studio level connections.
