Switched Mult 1U Manual 2
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.
Changes or modifications not expressly approved by Intellijel Designs, Inc. could
void the user’s authority to operate the equipment.
Any digital equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications.
This device meets the requirements of the following standards and directives:
EMC: 2014/30/EU
EN55032:2015 ; EN55103-2:2009 (EN55024) ; EN61000-3-2 ; EN61000-3-3
Low Voltage: 2014/35/EU
EN 60065:2002+A1:2006+A11:2008+A2:2010+A12:2011
RoHS2: 2011/65/EU

INSTALLATION 
This module is designed for use within
an Intellijel-standard 1U row, such as
contained within the Intellijel 4U, 7U and
Palette Eurorack cases. Intellijel’s 1U
specification is derived from the
Eurorack mechanical specification set
by Doepfer that is designed to support
the use of lipped rails within industry
standard rack heights.
Because this is a passive module, it
requires no power to operate.

Ensure your case has enough free space (hp) to fit the new module. To prevent screws or other
debris from falling into the case and shorting any electrical contacts, do not leave gaps between
adjacent modules, and cover all unused areas with blank panels. Similarly, do not use open frames
or any other enclosure that exposes the backside of any module or the power distribution board.
You can use a tool like ModularGrid to assist in your planning.

Switched Mult 1U Manual 3

OVERVIEW 
Switched Mult 1U is an expandable, dual-bus, 6-jack passive signal multiplier, with a 3-position
switch to facilitate asymmetrical routings — enabling each jack to be a mult of the X bus; a mult of
the Y bus; or to be turned off entirely.
A signal multiplier accepts an input signal and routes it to multiple outputs simultaneously. For
example, you might want a sequencer’s GATE to trigger two different envelopes — one to control
volume and one to control filter frequency. In order to accomplish this, you need a signal multiplier.
In addition, each Switched Mult 1U features a pair of 3-pin Link connectors on the rear panel. These
let you connect other 3-pin Link devices, such as an XY I/O 1U module, or even additional
Switched Mult 1U modules (handy for distributing mults across the width of your case).
FRONT PANEL 
[1] Jacks : Each of these six unbuffered jacks
can be assigned to either the X bus; the
Y bus; or switched off entirely, using the
corresponding Bus Switches [2] .
Plug an audio or CV signal into one jack, and
an unbuffered version of it will appear at
every other jack that has its Bus Switch [2]
set to the same position.
[2] Bus Switches : Each jack [1] has a
dedicated 3-position Bus Switch:
●X Bus (top) : When a switch is in the up
position, its corresponding jack accesses the X bus multiplier.
●Y Bus (top) : When a switch is in the down position, its corresponding jack accesses the
Y bus multiplier.
●OFF (middle) : When a switch is in the middle position, it is disabled and not connected to
either bus.
Switched Mult 1U Manual 4

In this illustration, we see that jacks 1 , 3 , and 5
are switched to the X bus, and jacks 2 , 4 , and 6
are switched to the Y bus — providing two
separate mults.
In this illustration, we see that jacks 1 , 3 , and 5
are switched to the X bus, while jacks 2 and 4
are switched to the Y bus. Jack 6 is switched off
(middle position), so it carries no signal.
If you were to switch jack 6 to the X position (up),
it will carry a mult of the X input (jack 1 ); if you
were to switch jack 6 to the Y position (down), it
will carry a mult of the Y input (jack 2 ).
Switched Mult 1U Manual 5

BACK PANEL 
There are two 3-pin Link connectors on the rear panel, and each Switched Mult 1U module ships
with one 3-pin Link cable, which you use to connect other 3-pin Link modules. Common pairings
include:
●XY I/O 1U : Connect the middle (JP2) 3-pin Link connector on the back of the XY I/O 1U to
either of the 3-pin Link connectors on the back of the Switched Mult 1U . Now, any signal
patched into the X jack on the XY I/O 1U is multed to any Switched Mult 1U jacks that have
their Bus Switches set to the X (up) position. Similarly, any signal patched into the Y jack on the
XY I/O 1U is multed to any Switched Mult 1U jacks that have their Bus Switches set to the
Y (down) position.
● Additional Switched Mult 1U modules : Connect either of the 3-pin Link connectors on the back
of Switched Mult #1 to either of the 3-pin Link connectors on the back of Switched Mult #2 .
Now the X bus is shared across both Switched Mults, as is the Y bus. You can chain more
modules together in the same way, which can also be useful for spreading mult jacks across the
width of your modular case.
