BEHRINGER / MODAMP MODULE 1005

BEHRINGER Eurorack modular synthesizer, reproducing the circuitry of the original System 2500 from the 70s. Feature-rich ring modulator and VCA module.

Features.
'70s Classic 1005 Analog ModAmp Module
Full-scale reproduction of the “2500” series circuit
Consists of a discrete balanced modulator and VCA
Balanced modulator takes two input signals (DC?20 kHz) and multiplies the two signals to produce an output
Gives inharmonic overtones and creates complex waveforms
Two precision voltage outputs control the frequency of the normally connected VCO
Modulation is activated by push-buttons (Mod and Unmod)
In Unmod mode, input A signal is sent to the output without modulation, level is set by the Unmod gain control
Modulation can be switched on or off by a patchable trigger or gate signal on the module
VCA accepts output from modulator and changes output signal level according to sum of gain control voltage and external control voltage
Two external VCA control signals can be attenuated via front panel controls
VCA mode can be either exponential or linear
Eurorack specifications: 16 HP
