Mutable Instruments Shades User Manual

Mutable Instruments | Shades

Shades requires a -12V / +12V power supply (2x5 pin connector). The ribbon cable connector must be
aligned so that the red stripe of the ribbon cable (-12V) is on the same side of the module’s power header
as the “Red stripe” marking on the board. The module draws 15mA from both the +12V and -12V supply
rails.

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.

Each of the 3 channels of Shades can act as an attenuator or attenuverter.

A. Function selector This control selects configures the channel as an attenuator (lower position) or as

an attenuverter (upper position).

B. Gain If the channel is configured as an attenutor, the gain ranges from 0 to 1. The signal is muted when

the knob is turned fully counter-clockwise, and is passed without attenuation when the knob is turned fully
clockwise.

If the channel is configured as an attenuverter, the gain ranges from -1 to +1. The signal is inverted when
the knob is turned fully counter-clockwise, and is passed without attenuation when the knob is turned fully
clockwise. When this knob is set at 12 o’clock, the signal is muted.

1. Signal input. When nothing is patched into this input, a constant voltage of +5V (or +10V) is sent to the

attenuverter/attenuator. Thus, a constant voltage of adjustable level and polarity will be generated on the
output. The three jumpers at the back of the module select which voltage is sent to each of the three
inputs - +5V, +10V, or +0V (when the jumper is removed).

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 and 2, output 3 will contain the sum of all
three channels.

When output 1 is left unconnected, the signal on output 2 is the sum of channels 1 and 2. Channel 3 can
be used for another purpose (attenuation, attenuversion, or constant CV generation).

When output 1 and 2 are left unconnected, the signal on output 3 is the sum of channels 1, 2 and 3.

Because Shades’ outputs are daisy-chained, the module can be used as an offset generator.

Leave channel 1’s input and output unpatched.1.
Connect a CV source to channel 2’s input.2.
Channel 2’s output will contain a scaled and offset copy of the input signal. Use channel 1’s knob to adjust the

3.
offset, and use channel 2’s knob to adjust the amplitude and polarity of the CV.

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.
