INSTALLATION
Intellijel Eurorack modules are designed to be used with a Eurorack-compatible
case and power supply. We recommend you use Intellijel cases and power
supplies.
Before installing a new module in your case, you must ensure your power supply
has a free power header and sufficient available capacity to power the module:
- Sum up the specified +12V current draw for all modules, including the new one. Do the same for the -12 V and +5V current draw. The current draw will be specified in the manufacturer’s technical specifications for each module.
- Compare each of the sums to specifications for your case’s power supply.
- Only proceed with installation if none of the values exceeds the power supply’s specifications. Otherwise you must remove modules to free up capacity or upgrade your power supply.
You will also need to 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. Failure to
adequately power your modules may result in damage to your modules or power
supply. If you are unsure, please contact us before proceeding.
Installing Your Module
When installing or removing a module from your case always turn off the power
to the case and disconnect the power cable. Failure to do so may result in
serious injury or equipment damage.
Ensure the 10-pin connector on the power cable is connected correctly to the
module before proceeding. The red stripe on the cable must line up with the
-12V pins on the module’s power connector. The pins are indicated with the
label -12V, a white stripe next to the connector, the words “red stripe”, or
some combination of those indicators. Sometimes the connectors are shrouded,
ensuring the cable can only be oriented in one direction.
Most modules will come with the cable already connected but it is good to
double check the orientation. Be aware that some modules may have headers that
serve other purposes so ensure the cable is connected to the right one.
The other end of the cable, with a 16-pin connector, connects to the power bus
board of your Eurorack case. Ensure the red stripe on the cable lines up with
the -12V pins on the bus board. On Intellijel power supplies the pins are
labelled with the label “-12V” and a thick white stripe. Sometimes the
connectors are shrouded, ensuring the cable can only be oriented in one
direction.
If you are using another manufacturer’s power supply, check their documentation for instructions.
Once connected, the cabling between the module and power supply should
resemble the picture below:
Before reconnecting power and turning on your modular system, double check
that the ribbon cable is fully seated on both ends and that all the pins are
correctly aligned. If the pins are misaligned in any direction or the ribbon
is backwards you can cause damage to your module, power supply, or other
modules.
After you have confirmed all the connections, you can reconnect the power cable and turn on your modular system. You should immediately check that all your modules have powered on and are functioning correctly. If you notice any anomalies, turn your system off right away and check your cabling again for mistakes.
OVERVIEW
Mixup is a versatile, expandable audio mixer for eurorack format. It has six front panel inputs and two outputs. Inputs 1 and 2 are single-channel mono inputs, each with its own mute switch and level control; Input 3 is a dual- channel stereo input with a shared mute and level control; and input 4 is an auxiliary unity-gain, non-mutable stereo input.
Using the 3-pin Link connectors on the back panel, you can chain multiple Mixups together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing around larger systems. You can even use the Intellijel Stereo Mix 1U and XY IO 1U modules in these back-panel chains. Using these same Link cables, you can connect Mixup directly to the ¼” audio jacks on an Intellijel Palette Case, a 7U case with 2nd-generation Audio Jacks Board, an Outs module, or a v2 Headphones 1U.
Because Mixup is designed specifically for audio (and not for CV mixing), it’s AC-coupled (which reduces the potential for `pops’ when muting and unmuting audio), and it uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.
FRONT PANEL
The front panel consists of a number of Control elements (switches, knobs, and
an LED), plus several input and output jacks. These are described below.
Controls
[1] LEVEL 1 – This attenuator reduces the IN 1 mono audio level sent to both MIX outputs.
[2] LEVEL 2 – This attenuator reduces the IN 2 mono audio level sent to both MIX outputs.
[3] LEVEL 3 – This attenuator reduces the IN 3L and IN 3R stereo audio level sent to the MIX outputs.
[4] MUTE 1 – In the down position, this switch mutes IN 1 — removing it from the MIX outputs.
[5] MUTE 2 – In the down position, this switch mutes IN 2 — removing it from the MIX outputs.
[6] MUTE 3 – In the down position, this switch mutes both IN 3L and IN 3R — removing them from the MIX outputs.
[7] CLIP LED – This LED lights when the sum of all the inputs (from the front panel jacks plus the rear panel serial bus) causes either side of the stereo MIX output to clip. Obviously, the more inputs you feed into Mix-up (or the more Mix-ups you feed into each other), the greater the potential to overdrive the Mix bus. So if the CLIP LED lights, consider reducing the various LEVEL knobs to maintain a clean, unclipped output.
Inputs & Outputs
[A] IN 1 – Mono audio input 1. Mix-up routes the audio from IN 1 to both the MIX L and MIX R outputs. It can be muted with the MUTE 1 switch, and its audio level is determined by the LEVEL 1 knob.
[B] IN 2 – Mono audio input 2. Mix-up routes the audio from IN 2 to both the MIX L and MIX R outputs. It can be muted with the MUTE 2 switch, and its audio level is determined by the LEVEL 2 knob.
[C] IN 3L – This is the left side of stereo audio input 3. Mix-up routes the audio from IN 3L to the MIX L output. It can be muted (along with IN 3R ) using the MUTE 3 switch, and its audio level (along with IN 3R ) is determined by the LEVEL 3 knob. If nothing is plugged into IN 3R , then IN 3L acts like a mono input, and Mix-up routes its signal to both the MIX L and MIX R outputs.
[D] IN 3R – This is the right side of stereo audio input 3. Mix-up routes the audio from IN 3R to the MIX R output. It can be muted (along with IN 3L ) using the MUTE 3 switch, and its audio level (also along with IN 3L ) is determined by the LEVEL 3 knob. If you wish to use input 3 for mono instead of stereo, simply plug a mono signal into the IN 3L jack, and leave the IN 3R jack unconnected.
[E] IN 4L – This is the left side of stereo audio input 4. Mix-up routes audio directly from IN 4L to the MIX L output, and has neither a mute switch nor a level knob. If nothing is plugged into IN 4R , then IN 4L acts like a mono input — appearing at both the MIX L and MIX R outputs.
[F] IN 4R – This is the right side of stereo audio input 4. Mix-up routes audio directly from IN 4R to the MIX R output, and has neither a mute switch nor a level knob. If you wish to use input 4 for mono instead of stereo, simply plug a mono signal into the IN 4L jack, and leave the IN 4R jack unconnected.
[G] MIX L – This is the mixed audio output of all audio on Mix-up’s left bus. This includes audio from IN 1, IN 2, IN 3L, IN 4L , plus all left- channel audio from other Mix-ups you might connected to its back panel CHAIN-IN connector.
[H] MIX R – This is the mixed audio output of all audio on Mix-up’s right bus. This includes audio from IN 1, IN 2, IN 3R (or IN 3L if IN 3R is not connected), IN 4R (or IN 4L if IN 4R is not connected), plus all right-channel audio from other Mix-ups you might connect to its back panel CHAIN-IN connector.
BACK PANEL
Each Mix-up module features a pair of rear panel connectors, which enable you to serially connect multiple Mix-ups to create a larger mixer with more inputs, or to connect Mix-up directly to the ¼” jacks on a compatible Intellijel case, an Outs module, or a v2 Headphones 1U.
[1] CHAIN-OUT – This connector taps into the Left and Right MIX bus outputs. Use the supplied link cable to connect the CHAIN-OUT of one Mix- up to the CHAIN-IN connector on another compatible module (such as another Mix-up; a Stereo Mix 1U; an Outs module; or a v2 Headphones 1U).
[2] CHAIN-IN – This connector adds another pair of inputs directly to the Left and Right MIX bus. Use the supplied link cable to connect the CHAIN-IN of one Mix-up to the CHAIN-OUT connector on another compatible module (such as another Mix-up or a Stereo Mix 1U). The CHAIN- IN connector is essentially another input, much like “Input 4.”
The following sections illustrate a few of the many possible device connections offered by the back panel’s pair of 3-pin LINK connectors.
IMPORTANT : Never use the 3-wire Link cable to directly connect a Mix- up module to an Intellijel Pedal I/O module. Although both modules use this same cable/connector — they serve different purposes and carry different signals.
Connecting Mix-up Directly to the Audio Jacks on your 7U Case
If you have a 2nd generation Audio Jacks board installed in your Intellijel 7U
Performance Case, you can connect one or two Mix-ups directly to these jacks.
This connection method does not work with a 1st generation Audio Jacks board,
though you can purchase and easily install a 2nd generation board in your
case.
You can distinguish 1st generation boards (included with cases built before
early 2019) by the single connector along the bottom of the Audio Jacks board.
2nd generation boards have a large shrouded header flanked by two smaller
shrouded headers, flanked by two link connectors.
To Connect the Mix-up to a 2nd Generation Audio Jacks board:
- Connect one end of the supplied 3-wire Lnk cable into the CHAIN-OUT on your Mix-up.
- Connect the other end to either of the two 3-pin Link connectors on the Audio Jacks board. The left connector uses the two left jacks for L/R Stereo outputs, while the right connector uses the two right jacks.
In this scenario, the audio jacks work as unbalanced outputs.
You can connect up to two Stereo Mix 1U’s to the Audio Jacks Board, or you can
even combine one with another 3-pin Link product (such as a Pedal I/O 1U).
Similarly, you can connect a Mix-up’s CHAIN-IN connector to either of the two 3-pin connectors on the Audio Jacks board and feed external audio from the corresponding jacks into the Mix-up bus.
Connecting Mixup Directly to the Audio Jacks on your Palette Case
If you have an Intellijel Palette case, you can connect Mix-up directly to its ¼” audio jacks. You can choose whether you want the ¼” jacks to send audio out of Mix-up, or into it.
-
To send unbalanced, line-level mixed audio directly from Mix-up to the ¼” audio jacks on the
Palette, connect the 3-wire link cable (provided with your Mix-up module) between Mix-up’s CHAIN-OUT connector and the single 3-pin Link connector on your Palette 62, or to one of the two Link connectors on the Palette 104 (depending on which pair of jacks you wish to use).
-
To send unbalanced, live-level audio directly into Mix-up from the ¼” audio jacks on the Palette, connect the 3-wire link cable (provided with your Mix-up module) between Mix-up’s CHAIN-IN connector and the 3-pin Link connector on your Palette 62, or to one of the two Link connector on the Palette 104 (depending on which pair of jacks you wish to use).
Connecting Mix-up to an Intellijel Outs Module
If you own an Intellijel Outs module, you can connect it directly to the Mix- up using the included link cable. To do so:
- Using the 3-wire link cable provided with your Mix-up module, connect one end of it to the CHAIN-OUT 3-pin connector on Mix-up, and the other end to the 3-pin connector on the Outs module.
- IMPORTANT! On the back of the Outs module, remove the JP1 jumper connector and put it in a safe place.
This jumper is what normalcy the Outs module’s Left input to its Right input. Since the Mix-up module has its own Left-to-Right Norma ling, 3-pin Link connections require removal of this jumper to achieve expected operation and optimum sonic fidelity.
Mix-up’s MIX L and MIX R outputs are now sent directly to the left and right inputs on your Outs module without patching the front panels.
Connecting Mix-up to a v2 Headphones 1U Module
If you own an Intellijel Headphones 1U module (version 2 only), you can connect it directly to the Mix-up using the included link cable. To do so:
-
Confirm you have a “version 2” Headphones 1U module.
Version 2 modules, in production since August 2019, have a 3-pin Link connecter and a jumper on the rear panel. Version 1 modules do not. -
Using the included 3-wire link cable, connect one end of it to the CHAIN-OUT 3-pin connector on Mix-up, and the other end to the 3-pin input connector on the Headphones 1U module.
-
IMPORTANT! On the back of the Headphones 1U module, remove the JP1 jumper connector and put it in a safe place.
This jumper is what normalcy the Headphones 1U module’s Left input to its Right input. Since the Mix-up module has its own Left-to-Right Norma ling, 3-pin Link connections require removal of this jumper to achieve expected operation and optimum sonic fidelity. -
Mix-up’s MIX L and MIX R outputs are now duplicated directly to the left and right inputs on your Headphones 1U module without patching the front panels. Mix-up Manual
