XY I/O 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

INSTALLATION 
This module is designed for use within an
Intellijel-standard 1U row, such as
contained within the Intellijel 4U and 7U
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 XY IO 1U is a passive module, it
requires no power to operate.

OVERVIEW 
Use this module to tap into the 3-pin LINK connector used in several Intellijel products, including
Mixup , Switched Mult 1U , Pedal I/O and the various Palette and 7U cases (NOTE: 7U cases
requires a 2nd Generation Audio Jacks Board).
It uses two 3.5mm TRS jacks, which accept insert cables to provide send/return capability to a pair
of Pedal I/O’s, or additional stereo inputs (or outputs) to a pair of Mixups, or one of each.
A third 3-pin Link connector on the back panel allows the X and Y jacks to sum with the X and Y
busses on a Switched Mult 1U, or to access the L/R (or Send/Return) jacks on a single connected
module or case without needing a stereo cable.
FRONT & BACK PANELS 
[X] X - This stereo 3.5mm (tip/ring/sleeve) jack connects to
JP1 [1] and JP2 [2] on the back panel as follows:
TIP : connects to both JP1 PIN 1 and JP2 PIN 1
RING : connects to JP1 PIN 3
SLEEVE : Ground
[Y] Y - This stereo 3.5mm (tip/ring/sleeve) jack, connects to
JP2 [2] and JP3 [3] on the back panel as follows:
TIP : connects to both JP3 PIN 1 and JP2 PIN 3
RING : connects to JP3 PIN 3
SLEEVE : Ground
The illustration on the right shows how the X and Y jacks
are wired to the JP1 , JP2 and JP3 jacks on the back
panel.
XY I/O 1U Manual 4

[1] JP1 - This 3-pin LINK connector is internally wired to the X [X]
TRS jack on the front panel as follows:
PIN 1 : connects to X TIP
PIN 2 : connects to ground
PIN 3 : connects to X RING
Connect this to another module’s 3-pin Link Connector.
Example 1: Mixup - Connecting JP1 to the CHAIN IN on an
Intellijel Mixup gives you an extra stereo input through the front
panel X jack, where X TIP = LEFT CH of Mixup, and X RING = RIGHT CH of Mixup.
Example 2: Pedal I/O - Connecting JP1 to a Pedal I/O provides you with send and return on
a single 3.5mm TRS insert cable, where X TIP = SEND and X RING = RETURN .
[2] JP2 - This 3-pin LINK connector is wired to both the X [X] and Y [Y] TRS jacks on the front
panel. Specifically:
PIN 1 : connects to X TIP
PIN 2 : connects to ground
PIN 3 : connects to Y TIP
This has numerous uses, including:
● Connecting a Switched Mult 1U, such that an extra jack is added to both the
Switched Mult’s X and Y busses.
● Connecting a Pedal I/O without using a TRS insert cable. Specifically:
X jack (TIP) = SEND to Pedal
Y jack (TIP)= RETURN from Pedal.
● Feeding the Left and Right CHAIN IN connector on a Mixup using regular mono
eurorack cables. Specifically:
X jack (TIP) = LEFT input to Mixup
Y jack (TIP)= RIGHT input to Mixup.
[3] JP3 - This 3-pin LINK connector is internally wired to the Y [Y] TRS jack on the front panel as
follows:
PIN 1 : connects to Y TIP
PIN 2 : connects to ground
PIN 3 : connects to Y RING
This works as described for JP1 , and provides the same connection options to external
modules, except that the Y jack (and not the X ) is connected to JP3.

OTHER USES 
Other usages are possible given a bit of ingenuity. These include:
● Make a Midi TRS Type-A to Type-B converter by cross patching the pins on the back with a
jumper cable
● Make an ⅛" Floating Ring converter by linking the two together with only 2 of the pins
● Simple ¼" to ⅛" converter with the Case Jacks
● Add an additional set of 1/8” inputs to Mixup (via Mixup’s CHAIN IN) — handy for patching in
small external synths (like Korg’s Volca series), which have 1/8” outputs.
● Add additional jacks to the X and Y busses on a Switched Mult 1U.
● Use the Jacks as an I2C
(NOTE)
header to link I2C modules across cases
● I2C
(NOTE)
from something like the ER-301 (3Pin) to the 16-N Faderbank (TRS)
NOTE: Mileage may vary with I2C, depending on the hardware involved.
