Doepfer A-135-3 Eurorack Voltage Controlled Stereo Mixer Module
Doepfer A-135-3 Voltage Controlled Stereo Mixer
The A-135-3 is a voltage controlled stereo mixer with 4 inputs. Behind a front panel with 8hp only either linear VCAs (voltage controlled amplifiers) and the mixer based on the VCAs are available.
Controls, Inputs and Functions of each inputs
• Level (manual control of the VCA amplification), small rubberized knob (L1 - L4)
• Control Voltage Input with associated attenuator (CV1 - CV4), for the full VCA control range about 0... +5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker
• Signal Input Left / Right (InL1 - InL4 / InR1 - InR4)
• The signal inputs are not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5V - +7.5V without clipping. In case of higher levels an external attenuator is required
• Crosstalk between two channels: better than - 80dB
• Signal attenuation at 0V CV: better than - 80dB
• Total harmonic distortion: typ. 1%
• Control voltage feedthrough: max 15mV
