Veils requires a -12V/+12V power supply (2x5 pin connector). The red stripe of the ribbon cable (-12V side) must be oriented on the same side as the “Red stripe” marking on the board. The module draws 50mA from the -12V rail and 50mA from the +12V rail. Current consumption can reach 70mA on either rail depending on the color and brightness of the LEDs.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
This device meets the requirements of the following standards: EN55032, EN55103-2, EN61000-3-2, EN61000-3-3, EN62311.

Veils provides four VCAs with an adjustable response curve and an offset control. Their outputs are daisy-chained, allowing adjacent groups of 2, 3, or all 4 channels, to be mixed together.
Controls, inputs and outputs
A. Response curve. Continuously variable between exponential and linear. Because the exponential function grows rapidly, very high gains (above 100) can be achieved with an exponential response curve combined with a large positive offset. Beware of clipping!
B. Offset control. This control adds a positive offset to the CV signal, for example to obtain a unipolar modulation from a bipolar LFO.
C. Gain CV amount. Amount of gain (amplitude) modulation from the CV input 24), or direct gain control when no cable is patched in the CV input. When set to the maximum, a CV of +5V yields a gain of 1 (0dB), and a CV above +5V might cause distortion.
1. Gain indicator LED. Its brightness is proportional to the VCA gain, on a dB scale. The LED is off when the signal is muted.
2. Gain CV input. Normalized to a constant +8V.
3. DC-coupled signal input. Accepts audio or CV signals.
4. Output indicator LED. Its brightness represents signal level, and its color represents signal polarity (green = positive).
5. 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, output 4 will contain the sum of all four channels.
