Doepfer A-113 Subharmonic Generator red 7-segment display

The Doepfer A-113 Eurorack Subharmonic Generator Module is a Eurorack subharmonic generator module, with a master frequency input, 4 subharmonic outputs, and 1 mix output. The A-133 is a special dual voltage controlled amplifier that enables both positive and negative amplifications. Negative amplification means in this context that the signal is inverted. The main application of the module is the processing of control voltages, e.g. ADSR or LFO. The amplification range is about  -2.5....0....+2.5 (other amplification ranges for small additional charges, e.g. -1...+1 or -5...+5). Amplification can be adjusted manually (Man control) and by an external control voltage with attenuator (CV). The present amplification is displayed with two LEDs: one for positive and one for negative amplifications (not a signal display but amplification diplay, similar to A-134).

The main features of the Doepfer A-113 Eurorack Subharmonic Generator Module include:

• Inputs: master frequency (rectangle/pulse input), foot contr. 1 + 2 (gate 1+2)
• Outputs: 4 single outputs, 1 mixture output
• Width: 26HP / 131.8 mm
• Depth: 90 mm (measured from the rear side of the front panel)
• Current: 30mA + 100mA@+5V
• The A-113 module requires an additional +5V power supply with 100mA 
  • (e.g. the separate +5V power supply or the +5V low-cost adapter)
