This guide explains how to configure and customize your KLEMENTZ Dub Mixer with the KZ Configurator. Everything happens in your browser, on a Mac or a PC: you take the machine’s configuration file, edit it in the configurator, then put it back into the machine.
What you can set in the configurator
The knobs and buttons on the front panel stay your playing controls. The configurator sets everything behind them: how the machine outputs sound, how it responds and how it lights up. A few examples.
Outputs and crossover
The “Outputs Config” module chooses between nine output modes: balanced stereo, stereo plus sub, two stereo outputs, or an active 2, 3 or 4-way split. In the split modes, the internal crossover sets the cutoff frequencies between sub, bass, mids and highs. Each mode is detailed in the output modes guide.
Inputs and FX sends
For each input, you set the high-pass filter and choose where the effect goes: to the internal unit, or to your external unit plugged into FX SEND and FX RTN (see the effects loop guide). On CH1 and CH2, you also choose where the send is taken: after the crossfader (default), before the crossfader, or before volume and filters. The AUX inputs also have a mic gain setting.
Crossfader
Four curves to choose from, from a smooth fade to a hard “Fast Cut”, with an adjustable threshold for the latter.
Delay, samples and lights
The internal delay has its own high-pass and low-pass filters, a ping-pong mode and a “Vintage Sound” setting that adds tape wobble. You also set how the sample player behaves (retrigger, fade-out on stop, trigger mode), the brightness of the VU meters and buttons, and the maximum headphone and master level.
Changing the configuration, step by step
1. Connect your machine over USB-C
Switch your Dub Mixer on and connect it to your computer with a USB-C cable. It shows up as a USB drive, named “DUB MIXER” since V5. Inside, you will find the CONFIG.CFG file.
2. Load the file into the configurator
Open the KZ Configurator and log in with the account you used for your order. Drop the CONFIG.CFG file onto the upload area, then click “Upload”.
Your browser may then ask you to select your machine. This only sends us its latest crash report, if it has one: your settings are not changed, and you can simply close that window.
3. Adjust, then download the new file
The modules are laid out on the machine’s front panel: click an area to open its settings. Prefer a list? Switch to the “Blocks” view. When everything is ready, click “Download Config”.
4. Replace the old file on the drive
Copy the downloaded file onto the drive, replacing the old CONFIG.CFG. If your browser renamed it, for example to “CONFIG (1).CFG”, rename it back to CONFIG.CFG.
5. Eject the drive
On a Mac or on Windows, eject the drive properly before unplugging.
6. Unplug the USB-C cable
Unplug the cable: the machine restarts and applies your new configuration.
What changes with V5 Standard
V5 Standard is available. These improvements are shared by Standard and Pro. They concern V5 firmware; the Pro RGB palettes have a separate hardware requirement.
Recall your settings at startup
V5 Standard recalls HP/LP and EQ on/off states, the selected internal FX preset and each input’s INT./EXT. FX destination. Recall applies to settings that have been saved. Autosave checks for changes every 30 seconds and waits for sample playback to end before writing. Internal effects start with parameters that follow the physical positions of their knobs.
Smoother controls and selectable FX send positions
V5 Standard provides more progressive level adjustment on CH1, Master, Sample Player, FX Return and internal effect outputs. Frequency control is finer, and Sample Player pitch now follows a linear response.
For CH1 and CH2, choose where the signal feeds the effects: after the crossfader, before the crossfader, or before volume and filters. In Mic mode, a fourth option doubles the maximum of the Gain control.
Prepare and play your samples
Startup is faster. Background pack preparation also reduces the wait before the first trigger. New compressed mono and stereo sample formats use less storage.
Existing PCM12 packs remain compatible. Packs are created in the configurator’s pack editor, which is planned for V5 Pro, along with storing eight packs and switching between them with TRIG + TYPE.
Brightness, USB storage and updates
V5 Standard lets you adjust VU-meter and button intensity on every PCB generation. Standard keeps the default colours. Palette selection, VU colour gradients and the RGB brightness limit are planned for Pro on RGB-equipped PCB V5 or newer.
The USB drive identifies itself as “DUB MIXER”, with improved detection when the cable is already connected at startup. V5 improves handling of invalid update files and early restarts. If an update resets the configuration, an existing Pro activation is preserved. V5 also provides a way to activate a valid Pro upgrade directly over USB.
What belongs to the upcoming V5 Pro
The direct configurator connection, live editing, the pack editor, USB audio, six FX preset slots, eight onboard sample packs and independent three-band EQ for AUX1 and AUX2 are planned for V5 Pro. The Standard configuration procedure in this guide uses the CONFIG.CFG file. USB audio is not part of Standard.
Restoring the factory settings
If your settings go wrong, there is no default file to download: both the configurator and the machine can go back to the factory values.
From the configurator, the simplest way
Load your configuration, then click the Factory reset button at the top of the page, next to Download Config. It appears as soon as a configuration is loaded. The configurator tells you how many settings will go back to their factory value and asks you to confirm.
Then download the file and put it back into the machine, as in steps 3 to 6 above. Until you do, nothing has changed in the machine.
If the machine can no longer read its file
In that case, delete the configuration file: the machine will write a new one on its own.
- Plug in the USB-C cable: the Dub Mixer shows up as a USB drive.
- Copy
config.cfgto your computer if you want to be able to go back to it. - Delete
config.cfgon the drive. - Eject the drive, then unplug the USB-C cable: the machine reboots.
On startup it finds no configuration and writes a new one, with the factory settings. Your custom settings are gone: this is a reset, not an undo.
