• crackling impulses
• CV input for the internal clock oscillator
• Input for external clock
• zero-balanced noise output
• Balanced noise output

With the A-117-2 module, Doepfer offers a digital, voltage-controlled noise generator.

The module generates a random sequence of square-wave signals, the frequency of which can be adjusted from occasional "clicks" to noise. The noise color is clearly different from that of analog noise. In the lower frequency ranges, the A-117-2 produces atonal, noisy sounds reminiscent of bitcrush effects, making it particularly convincing in experimental patches.

If sequence the module and send the digital noise directly into a VCA modulated by an envelope, it's also a great choice for the techno and industrial crowd. The internal clock oscillator is manually adjustable in a wide range from 50Hz to 40kHz and can also be controlled via a CV input with its own attenuator. If needed, the internal clock can be replaced by an external one, e.g. an oscillator, high-speed VCO, LFO or a Midi-Clock. There are two outputs for the signal: zero-balanced (upper noise jack) and a purely positive output (lower noise jack). The balanced signal is primarily suitable for audio use, while the positive signal is ideal for control tasks such as random envelope triggering, random clock signal or random switching functions.
