About This Product

An authentic reproduction of the original “System 2500” circuitry from the 70’s that can fit in a standard Eurorack case. The best part? It’s at a very affordable price. Mix the MODAMP MODULE 1005 in with your existing rig or start your modular synth journey from here. Either way you’re sure to have a lot of fun.

Features:

• Classic 1005 analog ModAmp module from the '70s
• Authentic reproduction of the circuitry from the "2500" Series
• Consists of a discrete balanced modulator and VCA
• Balanced modulator accepts 2 input signals (DC to 20 kHz) and produces an output that is a multiplication of the two signals
• Creates complex waveforms with in-harmonic overtones
• 2 precision voltage outputs control the frequency of the VCO's that are typically connected
• Modulation is activated by illuminated push buttons (Mod and Unmod)
• In Unmod mode the signal at input A passes to the output without any modulation and the level is set by the Unmod Gain control
• Modulation can be switched on and off by trigger or gate signals which can be patched into the module
• VCA accepts the output from the modulator and modifies the output signal level according to the sum of the Gain control and external control voltages
• 2 external VCA control signals can be attenuated by front panel controls
• VCA mode can be selected as either exponential or linear
• Eurorack specs: 16 HP, XX mA +12 V, XX mA -12 V
