Channel Polarity And Gain; Modulation Attenuverter; Signal Input; Modulation Input - Mutable Instruments Blinds User Manual

Mutable Instruments | Blinds
A. Channel polarity and gain. At 12 o'clock, the channel is muted. Turn clockwise to amplify, turn
counter-clock- wise to amplify and invert.
B. Modulation attenuverter. Adjusts the amount and polarity of modulation from the modulation input (2),
i.e. how much, and in which direction, the channel polarity and gain will wiggle around the central value
set by A.

1. Signal input.

Blinds' inputs are DC-coupled and accept both audio and CV signals. This input receives
+5V when no patch cable is inserted.

2. Modulation input.

This input is also DC-coupled. When audio-rate signals are present on both the
signal and modulation input, Blinds works as a pure ring-modulator.

3. Signal output.

When no patch cable is plugged into an output, the signal from this channel is routed to
the next channel. For example, when no patch cable is patched into output 1, output 2 will contain the sum
of channel 2 and channel 1. If nothing is patched into outputs 1, 2 and 3, then output 4 will contain the
sum of all four channels.

4. Gain and polarity indicator.

The color corresponds to the polarity (green = positive, red = negative),
the bright- ness to the gain.

5. Output level and polarity indicator.

The following equation describes the operation performed by each channel:
Where Vout is the output voltage, Vin the input voltage, Vmod the control voltage, BigKnob and
SmallKnob the position of the big and small knobs, represented as a number between -1 and 1 (0 being
the 12 o'clock position).
Because Vin is normalized to +5V, when nothing is patched into Vin, this equation becomes:
