921A OSCILLATOR DRIVER

Attack, Decay, Sustain, Release. Control inputs for frequency and rectangular width are summing. A total of 10 overlapping LC networks are included. Attenuators reduce the gain or amplitude of any applied input signal, control or audio. The Moog is a 61 key duophonic keyboard designed for use with the Moog modular System 55, 35 and Model 15 analog synthesizers, as well as for use with vintage Moog modular synthesizers.

A sawtooth waveform is recommended for best synchronization results. The basic cutoff frequency of the Low Pass Filter is determined by the combination of fixed control voltage and frequency range in addition to the control input signals.

There are no reviews to display. This limited edition reissue of the Moog modular Model 15 is built to order, and is available in very limited quantities. Each module is then finished with a photo-etched aluminum panel, and placed in its new modular instrument.

04 – M15 – The 921A & 921B Oscillators

The A Low Pass Filter attenuates frequencies above the fixed control voltage cutoff point at a rate of 24dB per octave. Two ranges are provided on the Frequency potentiometer: Control inputs for frequency and rectangular width are summing.

This oscillator generates both sub-audio and audio frequencies for control and audio signal use. Multiple frequency control inputs can be plugged into this module in parallel. The A Fixed Filter Bank is a non-voltage controlled modifier, which emphasizes or reduces the gain of the center frequency bands indicated on each of the eight center pots, in addition to the cutoff points set by low pass and high pass filters at either frequency extreme.

They are wired in groups to a common A Oscillator Driver, which provides both exponential frequency control and rectangular width voltage control. The Voltage Controlled Oscillator is a variable waveform generator, which produces frequencies ranging from. The Model 15 oscillators offer rectangular wave forms in it’s specs as well. Using all original documentation as well as circuit board and art files for every module, Moog Engineers have painstakingly recreated this powerful and portable analog system.

Faithfully Recreating The Model 15 Over the course of 3 years Moog Music set out to research and build a faithful recreation of the classic Moog modular Model 15 analog synthesizer.

Each individual module is hand-stuffed and the components are hand-soldered to circuit boards using traditional wiring methods.

Four waveforms are available: Fixed level outputs for Sine, Triangle, Sawtooth and Rectangular waveforms are found at the right of the modules. A resultant lower frequency concentration for Pink Noise marks the difference between the two outputs, with white noise appearing in even intensity throughout the audio spectrum. Each Model 15 is hand-built to its original Moog factory specifications and is a true recreation of the original.

Two modes of gain response are available: Only total units will be made and sold worldwide. Using all of the original documentation, as well as the original circuit board and art files, Moog engineers have hand-built true recreations of the original instruments based on their factory specifications.

Two voltages are generated: This limited oscilltor of the Moog Model 15 modular synthesizer is built to order. S-Trigger is needed to operate from external sources. Already have an account?
