Legendary 2500 Series Dual Noise Source Module for Eurorack
The first 2500 series synth modules came out in the 70s and tended to be extremely expensive. They were mainly all discrete transistor designs with some op-amps as at the time op-amps were high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like The Who, Jean Michel Jarre, Vangelis, Kraftwerk and so many more, giving us some of the greatest records and film soundtracks weve ever heard. Modular synths were a landmark development in electronic music and today, its about to get better.
Features
- Classic 1016 analog dual noise and random voltage generator module from the ’70s
- Authentic reproduction of the circuitry from the 2500 Series
- The module consists of 2 identical white/pink noise and Random Voltage generators
- The noise outputs are generated from 2 independent transistor noise sources
- Filtering of the white noise is used to transform into pink noise and finally a slow random voltage
- 2 output attenuators enable the outputs to be reduced in volume
- White or Pink Noise are selectable via slide switch and LED indication
- Random Voltage can be switched on and off via slide switch with LED indication
- White noise is generated from 5 Hz to 20 kHz and Pink noise is filtered to attenuate the highs and boost the low frequencies resulting in equal energy per octave
- Slow random voltages feature peak signal power between 1 Hz and 10 Hz
- Eurorack specs: 14 HP, 45 mA +12 V, 15 mA -12 V
