|
The 1016 Dual Noise/Random Voltage Generator Module contains
two separate white noise generators with pink noise and slow random
outputs. The two noise outputs A and B, are generated from two independent
diode noise sources. Through filtering, the white noise is transformed
into pink noise and through additional filtering into a slow random
voltage. Output attenuators an on/off switches are provided for the two
noise sources and the random voltage outputs.
The White Noise Generator produces a flat bandwidth from 5Hz to 20 KHz. The Pink Noise is filtered to attenuate the highs and boost the low frequencies, resulting in equal energy per octave. The Slow Random output has peak signal power between 1Hz and 10Hz. The convenience jacks are located on the front panel and permit the user to have direct access to the lower matrix switch of the ARP synthesizer. (The noise produced is allegedly of higher quality than that produced by the 2600's circuits, with a less gritty texture!) There is also the 1040 Oscillator/Noise Generator Module which features one white and one pink noise source, a random voltage source and a VCO similar to the 1023
