Mutable Instruments Veils User Manual

Mutable Instruments | Veils

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. Veils’ outputs are daisy-chained, allowing
adjacent groups of 2, 3, or all 4 channels, to be mixed together.

A. Gain CV amount. Amount of gain (amplitude) modulation from the CV input (4), or direct gain control

when no cable is patched in the CV input. When this knob is turned fully clockwise, a CV of +5V yields a
gain of 1 (0dB), and a CV above +5V might cause distortion. Veils does not provide any offset control - a
module like Shades or Blinds can be used to pre-process the gain CV to offset it.

B. Response curve. Continuously variable between exponential and linear. Because the exponential

function grows rapidly, very high gains (above 10) can be achieved with an exponential response curve.
Beware of clipping!

1. DC-coupled signal input. Accepts audio or CV signals.

2. 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.

3. Indicator LED. Brightness represents signal level, and color represents signal polarity (green =

positive).

4. Gain CV input. Normalized to a constant +8V.

This product is covered by Mutable Instruments’ warranty, for one year following the date of manufacture.
This warranty covers any defect in the manufacturing of this product. This warranty does not cover any
damage or malfunction caused by incorrect use - such as, but not limited to, power cables connected
backwards, excessive voltage levels, or exposure to extreme temperature or moisture levels.

The warranty covers replacement or repair, as decided by Mutable Instruments. Please contact our
customer service ([e-mail]) for a return authorization before sending the
module. The cost of sending a module back for servicing is paid for by the customer.

Mutable Instruments encourages modding and hacking, but we will not service modified units or provide
any assistance in the realization of mods.
