Usage As An Attenuverter; Ring Modulator Functionality; Warranty Information - Mutable Instruments Blinds User Manual

Mutable Instruments | Blinds
In this case, the big knob controls an offset between -5V and +5V, and the small knob a gain between -1
and +1. In other word, each channel of Blinds can be used as an attenuverter with offset control circuit.
A ring modulator is an imperfect four-quadrant multiplier realized with a diode ring circuit. Because it is
based on a bipolar VCA circuit, Blinds realizes a purer sounding version of ring-modulation, very close to
the mathematical ideal of signal multiplication. Don't worry though, the familiar sounds of bells, american
metaphysical circuses and Daleks are still there!
When Blinds is used as a ring modulator, with audio rate signals going in both inputs, the big knob controls
a very interesting parameter: carrier rejection (how much of the unmodulated signal will "bleed" on top of
the ring-modulated signal).
Because of mechanical backlash in the construction of the potentiometer, the vertical mark on the panel
might not be perfectly aligned with the white pointer of the knob when a channel has zero offset. In
addition, some envelope generators or LFO might have a residual "bleed" voltage - they sometimes sit a
few mV below 0 after their release. Trust your ears and the LEDs when zeroing a channel!
