Overview

The wireframe images below expose the controls and inputs/outputs that the MOD Duo X has.

Device features

Inputs and outputs Dj technik MOD DUO X STUDIO EFFECTS DEVICE - fig
1

Audio input jacks
The MOD Duo X has two independent audio inputs, with configurable input gain for each input. You can set up the input gain through the device menu.
Expression/CV Input
The MOD Duo X has a port to connect an expression pedal or two control voltage inputs. You should define how you want to use it in the device menu.
Audio output jacks
The MOD Duo X has two independent audio outputs, with configurable output gain for each output. You can set up the output gain through the device menu.
Headphone/CV Output
The headphone output on the MOD Duo X monitors outputs 1 and 2. It is possible to set the volume level of the headphone output through the device menu.
On the MOD Duo X, you can also use this port to get two control voltage outputs. For that, you must select this option on the device menu.
Power jack
The MOD Duo X comes with its own approved power supply which outputs 12V, 2A over a center-positive barrel-type plug.
In order to work, the MOD Duo X requires at least 12W, 1.5A although this can cause problems when you connect Control Chain devices or other controllers. You also need to pay attention to the polarity of your plug, it must be central positive.
The plug diameter of the power supply must be Φ5.52.110mm
Power supplies such as this (https://www.amazon.com/Adapter-Transformers- Supply-Output-Listed/dp/B00DKSI0S8/ref=sr_1_5) are capable to power the MOD DUO X.
In summary, the power consumption of the MOD Duo X varies depending on the peripherals connected to the device. For example: Hooking up a USB hub to the USB-A port, and then hooking up multiple MIDI controllers to the hub will change the power requirements.
By using the provided power supply you are sure that you will never run out of juice.

Control Chain port
MOD Control Chain devices (such as the MOD Footswitch (https://www.moddevices.com/products/mod-footswitch)) have multiple benefits over MIDI Controllers.
MOD Control Chain devices have screens that show you on demand what each of the footswitches or actuators is assigned to control.
You can daisy chain up to 8 Control Chain devices (this was the maximum we tested) using a single cable from one Control Chain device to the other.
MOD Control Chain devices use an open protocol, which means that you and all of our community can contribute to improving it. You can also use the Arduino Shield (https://www.moddevices.com/products/arduino-shield) and build your own Control Chain device.
Last but not least, Control Chain devices also allow you to have more resolution from your actuators than the current MIDI Controllers.
NOTE: Please do NOT connect this port to a regular Ethernet port, it can damage your MOD Duo X.

USB Host port
In the most common scenario, this port is used to hook up a single USB-MIDI device, such as a MIDI-keyboard to control generator plugins.
Another common scenario is using this port to hook up a Bluetooth dongle for a wireless connection to your PC.
NOTE: The port can also be split up into multiple ports using a USB hub for connecting multiple USB devices to the MOD Duo X.

USB computer port
This port is mostly used to connect the MOD Duo X to your PC for setting it up. When executing a manual system update, its use changes to a mass storage device, so that you can copy the update file to the MOD Duo X.

DIN-MIDI I/O
The MOD Duo X also supports “old-school” DIN-MIDI devices, simply hook up your DIN-MIDI device to the appropriate port on the back and enjoy!
SPDIF out
The S/PDIF output on the MOD Duo X is a digital output that mirrors the two audio outputs. You can connect it to your audio interface.
