+
The options for adjusting the inputs are '''Stage''' and '''Fine Adjust'''.  
  
−
==Banks==
+
The '''Stage''' menu allows you to adjust the gain stage of the selected input. Inside of the '''Stage''' menu there are 3 options: '''Low''', '''Mid''' and '''High''', representing the following input gain levels:
−
If you want to use the MOD Duo without being connected to a computer, this is a very important section.
+
* Low = -22dB
 +
* Mid = -9.5dB
 +
* High = +3dB
  
−
Upon entering this section, you will see the banks that you have created using the web interface, as well as a bank that contains all your pedalboards, named "All".
+
You should select the gain stage that best applies to the instrument you have connected. Short press the knob to activate the selected gain stage.
  
−
By navigating to a bank and clicking on the left button, you can browse the pedalboards within that bank. Navigate to the pedalboard of your choice and click the left button to load that pedalboard, and make the bank the currently active bank.  
+
[[File:duo-manual-4.png]]
  
−
From this point onwards, you can use multiple ways of navigating through the pedalboards in the active bank:
+
Once you have chosen the desired '''Stage''' value you can return to the previous menu by selecting the '''Back to ...''' option.
−
# Repeat the procedure to navigate to and select a different pedalboard

Simply short press the knob to return to the previous menu.
−
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.
+
==Outputs==
  
−
The gain stages represent the following input gain:
+
The '''Output''' menu has only one option, which allows you to adjust the attenuation of the respective output. Turn the knob to adjust the value. To return to the previous menu simply short press the knob.

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 independant 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 independant audio outputs, with configurable output gain for each outut. 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.

TODO: Add plug dimensions, minimum power requirements

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

TODO: explain use for CC, advantage over MIDI

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, its use changes to a mass-storage device, so that you can copy the update-file to the MOD Duo.

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.

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

  • Hold the left knob to access and exit the device menu
  • Turn the left knob to scroll through the device menu
  • Press the left knob to enter the selected sub-menu or toggle the selected option

Right knob actions

  • Hold the right knob to access and exit the tuner
  • Press the right knob to change the input that the tuner is used for

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 through the web interface:

  • 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 sports 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: 180 mm
  • length: 160 mm
  • height: 74.7 mm

LED Audio meters

The LED colors represent the following input levels:

  • Off: below -30dB
  • Green: between -30dB and -12dB
  • Yellow: between -12dB and -3dB
  • Red: above -3dB
  • Blinking strong red: 0dB (CLIPPING!)

Adjusting Volumes

The MOD Duo allows each input and output volume to be individually adjusted. To access the Volume and Gains menu, first press and hold the left knob for one second. The SETTINGS menu will show up, now turn the left knob to select the Volume and Gains option and finally short press the knob to access it.

Once you have the Banks menu open, you can select any bank according to your preference. The name of each bank should give you an idea of the style of the pedalboards it stores. A short press on the knob will open the selected bank showing the pedalboards inside of this bank.

To load a pedalboard, make your selection by turning the knob, followed by a short press on the knob. Each time you load a pedalboard you can try how it sounds and once you find a pedalboard that you like, you can exit the Banks or Pedalboard menu by pressing and holding the left knob for one second.

Adjusting pedalboard parameters

As you might have noticed already, the default view of the displays shows the assigned parameters of the plugins for the current pedalboard. You will learn more about assigning parameters in the next chapter.

These parameters you see on the displays were considered important to be accessible to the user when the pedalboard is loaded. To adjust the value of each parameter you just need to turn the knob until the desired value is reached. More than one parameter can be assigned to the same knob, to cycle between them, short press the knob. On the top-right corner of each display you can see the index of the parameter being adjusted and the amount of assigned parameters on this display.

After you have changed the values you might want to save or reset them. The reset will restore the last saved values for all assigned parameters, while the save option will save the current parameters values to the current pedalboard. To access these options, press and hold the left knob for one second to open the SETTINGS menu, then turn the knob moving the selection until Current pedalboard option and short press the knob to select it.

Editing

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.

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 see how to do this!

Hooking up the MOD Duo

The MOD Duo has two completely independant inputs and outputs, as well as support for regular DIN-MIDI as well as 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:

  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)

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!
