"This module was tested at the factory on 12/13/2010, so it's still fairly new. It has been used gently and only in a smoke-free studio, so it's in perfect condition.
The Q116 Ring Modulator performs a variation of amplitude modulation in which two input signals are multiplied creating an output that contains the sum and difference of the input signals (called sidebands), but without the original input signals themselves. The result is a very strange clanging, bell-like sound that can only be created with a ring modulator. Useful for producing gong sounds, bell sounds, and many strange sounds having no description. Sometimes referred to as a 'Balanced Modulator'.
Specifications
Panel Size: Single width 2.125"w x 8.75"h.
Signal Levels: 10V PP maximum
Power: +15V@30ma, -15V@30ma
Usage and Patch Tips
Basics
Simply put, the Ring Modulator makes strange sounds by combining two signals. A simple patch would include an oscillator driven by the keyboard into the X input, and another manually controlled oscillator into the Y input, then patch the output to an amplifier which is driven by an envelope generator. The result will be a bell-like sound."
