To ensure a safe connection, follow the steps below.
 +
 +
# Turn down the volume of your amp and connect it to the OUTPUT jack(s)
 +
# Connect your instrument(s) to the INPUT jack(s)
 +
# Turn on the MOD Duo by plugging in its power adapter
 +
# Wait until the MOD Duo boots up
 +
 +
 +
===Inputs jacks===
 +
The MOD Duo has two independent audio inputs, with configurable input gain for each input. You can set up the input gain through the device menu.
 +
 +
===Output jacks===
 +
The MOD Duo has two independent audio outputs, with configurable output gain for each output. You can set up the output gain through the device menu.
 +
 +
===Headphone jack===
 +
The headphone output on the MOD Duo usually monitors output 1 and 2, although it can also be set up to monitor the inputs directly through the device menu. It is also possible to set the volume level of the headphone output through the device menu.
 +
 +
===Power jack===
 +
The MOD Duo 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 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 Φ5.5*2.1*10mm
 +
 +
Power supplies such as this are capable to power the MOD DUO.
 +
 +
In summary, the power consumption of the MOD Duo 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 [https://www.moddevices.com/products/mod-footswitch 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, what means that you and all our community can contribute to improve it. You can also use the [https://www.moddevices.com/products/arduino-shield 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.'''
 +
 +
===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 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.
 +
 +
===USB computer port===
 +
This port is mostly used to connect the MOD Duo to your PC for setting it up. When executing a manual system update, this port turns the MOD Duo into a mass-storage device, so that you can copy the update-file to the device.
 +
 +
===DIN-MIDI I/O===
 +
Finally, the MOD Duo also supports old-school DIN-MIDI devices, simply hook up your DIN-MIDI device to the appropriate port on the back and enjoy!
 +
 
==Actuators==
 
==Actuators==
 +
The two knobs and two footswitches make up the actuators that are present on every MOD Duo.
 +
 +

 +
When switching pedalboards with the footswitches is enabled:
 +
*Press the left footswitch to load the previous pedalboard in the active bank
 +
*Press the right footswitch to load the next pedalboard in the active bank
 +
 
==Displays==
 
==Displays==
 +
The MOD Duo has two large (2.8") LCD displays. The displays normally give dynamic information about the actions mapped to the device actuators, but they are also used for displaying the device menu and tuner.
 +
 +
==Dimensions==
 +
*width: 160 mm
 +
*length: 186 mm
 +
*height: 75 mm
 +
 +
==LED Audio meters==
 +
 +
From the v1.9 onwards the LEDs have smooth transitions between colours. The LED colours represent the following input levels:
 +
 +
*Off: below -40dB
 +
*Green fade in: between -40dB and -6dB
 +
*Green fully ON, fading in yellow: between -6dB and -1dB
 +
*Red: between -1dB and 0dB
 +
*Blinking strong red: 0dB (CLIPPING!)
 +
 +
=Adjusting Volumes=
 +

==Volume and gains==
+
==Accessing the graphical interface==
−
This section allows you to set the gain for the inputs and level of the outputs. The headphone has its own section, so check out the "Headphone" section for information about the headphone volume levels and settings.
 
  
−
When you notice that the LED's at the input side are blinking bright red, that means that your input signal is "clipping". In general, that is not a desired condition. Luckily, it can easily be resolved by lowering the input gain. Try a different gain-stage for the clipping input, or use the "Fine Adjust" option to take smaller steps.
+
The MOD Duo has a built-in graphical user interface (GUI), which means you don’t need to download any extra software in order to configure the device. To access the interface, you only need a web browser, such as Chrome, Safari or Firefox.
  
−
The gain stages represent the following input gain:
+
Once you are connected to your device you will be able to build and share your pedalboards, download new plugins, organize your banks for offline access and much more.
−
*Low: -22.0 dBu
 
−
*Medium: -9.5 dBu
 
−
*High: +3.0 dBu
 
  
−
For the outputs there is only a simple volume control, going from 0 (unity gain) all the way down to -127.0 dBu. It is recommended to keep the outputs set to unity gain, and resolving clipping on the outputs by reducing the gain in the pedalboard.

Overview

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

Duo-overview.png

Device features

The following sub-sections give information about the different physical device features: the inputs, outputs, actuators, displays and finally the dimensions of the device.

Inputs and outputs

Duo-manual-2.png

To ensure a safe connection, follow the steps below.

  1. Turn down the volume of your amp and connect it to the OUTPUT jack(s)
  2. Connect your instrument(s) to the INPUT jack(s)
  3. Turn on the MOD Duo by plugging in its power adapter
  4. Wait until the MOD Duo boots up


Inputs jacks

The MOD Duo has two independent audio inputs, with configurable input gain for each input. You can set up the input gain through the device menu.

Output jacks

The MOD Duo has two independent audio outputs, with configurable output gain for each output. You can set up the output gain through the device menu.

Headphone jack

The headphone output on the MOD Duo usually monitors output 1 and 2, although it can also be set up to monitor the inputs directly through the device menu. It is also possible to set the volume level of the headphone output through the device menu.

Power jack

The MOD Duo 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 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 Φ5.5*2.1*10mm

Power supplies such as this are capable to power the MOD DUO.

In summary, the power consumption of the MOD Duo 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) 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, what means that you and all our community can contribute to improve it. You can also use the 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.

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 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.

USB computer port

This port is mostly used to connect the MOD Duo to your PC for setting it up. When executing a manual system update, this port turns the MOD Duo into a mass-storage device, so that you can copy the update-file to the device.

DIN-MIDI I/O

Finally, the MOD Duo also supports old-school DIN-MIDI devices, simply hook up your DIN-MIDI device to the appropriate port on the back and enjoy!

Actuators

The two knobs and two footswitches make up the actuators that are present on every MOD Duo.

Knobs

The two knobs are used to access and navigate the device menu and tuner. They can also be freely mapped to the parameters of the plugins running inside the MOD Duo, through the web interface.

General knob actions

  • Turn a knob to change the value of the parameter assigned to it
  • Press a knob to cycle through the list of parameters assigned to it

Left knob actions

  • Press and hold the left knob to access and exit the Device Settings menu
  • Turn the left knob to scroll through the device menu
  • Press the left knob to toggle the selected option

Right knob actions

  • Press and hold the right knob to access and exit the tuner
  • Press the right knob to change the input that the tuner is used for
  • While on the Device Settings menu, press the right knob to get in sub-menus and toggle selected options visible on the right screen.

Footswitches

The two footswitches can be used to navigate through the pedalboards that are inside a bank (when set up that way). They can also be freely mapped to the parameters of the plugins running inside the MOD Duo, through the web interface.

General footswitch actions

  • Press the footswitch to change the value of the parameter mapped to it

Switching pedalboards with the footswitches

When switching pedalboards with the footswitches is enabled:

  • Press the left footswitch to load the previous pedalboard in the active bank
  • Press the right footswitch to load the next pedalboard in the active bank

Displays

The MOD Duo has two large (2.8") LCD displays. The displays normally give dynamic information about the actions mapped to the device actuators, but they are also used for displaying the device menu and tuner.

Dimensions

  • width: 160 mm
  • length: 186 mm
  • height: 75 mm

LED Audio meters

From the v1.9 onwards the LEDs have smooth transitions between colours. The LED colours represent the following input levels:

  • Off: below -40dB
  • Green fade in: between -40dB and -6dB
  • Green fully ON, fading in yellow: between -6dB and -1dB
  • Red: between -1dB and 0dB
  • Blinking strong red: 0dB (CLIPPING!)

Adjusting Volumes

MOD Duo allows each input and output volume to be individually adjusted.

Please refer to the Inputs and Outputs Device Settings section in the wiki for more information on that.

Tuning

DUOX-Tuner.png

MOD Duo has a built-in chromatic tuner that can be accessed by pressing and holding the right knob for one second. Both inputs can be used as the tuner input, to select between them short press the right knob. To exit the tuner press and hold the right knob for one second.

If you see a question mark on the tuner screen, it means the MOD Duo is not receiving any input or the input levels are too low.

Please refer to the Tuner section in the Device Settings page for more information.

Playing

After you have powered on and adjusted the volumes of your MOD Duo, it is time for playtime. The MOD Duo comes with many pedalboards ready to be used. They are organized in banks and can be accessed via SETTINGS menu.

Accessing the graphical interface

The MOD Duo has a built-in graphical user interface (GUI), which means you don’t need to download any extra software in order to configure the device. To access the interface, you only need a web browser, such as Chrome, Safari or Firefox.

Once you are connected to your device you will be able to build and share your pedalboards, download new plugins, organize your banks for offline access and much more.

Please refer to the Web GUI User Guide to learn all about it.

Overview shot of the pedalboard builder in the web interface

Accessing via USB cable

The easiest way to access the GUI is through the USB cable. Simply connect the USB cable, which you received along with your MOD Duo, to your PC or Mac. The operating system should recognize the MOD Duo as a network device and configure it automatically. However, this process may fail in certain Windows versions, if that is your case please check the troubleshooting page

After successfully connecting the MOD Duo to your PC or Mac, open your favorite browser and navigate to http://modduo.local (or http://192.168.51.1).


Accessing via Bluetooth

It is also possible to connect to your computer using a wireless Bluetooth connection. Check this page to learn how to do it!

True Bypass

MOD Duo has a true bypass circuit for each pair of input/output. This allows you to physically connect input 1 to output 1, and input 2 to output 2. The true bypass is enabled when the device is off and it is automatically disabled after the current pedalboard is loaded.

You can enable or disable the true bypass via the GUI, or use a plugin and assign this control to any actuator. See the Web GUI User Guide for more info.

You can also enable it via the Device Settings menu. Check Hardware bypass section on Device Settings page for more info.

Hooking up the MOD Duo

The MOD Duo has two completely independent inputs and outputs, as well as support for regular DIN-MIDI and USB-MIDI devices. It quickly becomes clear that many different possibilities exist for hooking up the MOD Duo in your setup.

In general, there are two scenarios for hooking up the MOD Duo:

  1. At setup time, with a computer connected to create new pedalboards
  2. For live use, possibly without a computer connected

For the first scenario, the only connection that you need to make is from the USB B port on the MOD Duo to your computer. (Bluetooth is possible in case that is preferred. Check here how to do it)

For the second scenario, it is possible to remove the connection to the computer completely, the MOD Duo works perfectly fine as a standalone device!
