Reloop Terminal Mix 2/4

The Reloop Terminal Mix 2 and Terminal Mix 4 use the same mapping in Mixxx.

在 1.11 版本新加入.

Sound hardware

The Reloop Terminal Mix 2 and Terminal Mix 4 have integrated multichannel sound cards. Usually, the TerminalMix runs very well with USB power only. If you experience issues especially when powering both main and booth outputs at high levels you should use the additional power supply (6v/1.5A). The official manual from Reloop states not to operate the unit at temperatures below 5°C/41°F as it might damage A/D converters and other components. However, the audio output may already start crackling if the temperature drops below 10°C.


Both TerminalMix 2 and 4 have a microphone and a switchable line/phono input that can be routed into Mixxx. The Microphone jack is at the front side of the controller, the RCA line jacks are at the back next to the line/phono switch. For both inputs there is a gain knob and a switch on the controller’s front side that toggles between routing the signal to the computer (SW) or mixing it directly with the main output (MST). MST allows to play music from external sources without any software, for example while setting up Mixxx software. Switch to SW if you want to use the line signal for vinyl control or AUX input, or if you want to record the microphone input with Mixxx, broadcast it, or put on effects.


At the front, there are two headphone jacks (1/8」 and 1/4“), both affected by the hard-wired TONE knob. At the back, there are unbalanced outputs for booth and main (RCA), as well as a balanced main output (1/4”). The output level of both main outputs, booth and headphone outputs are all controlled by respective hard-wired knobs in the center column which can’t be mapped to software.

Controller hardware / Maintenance

The jog wheels’ touch sensitivity can be adjusted separately. Refer to the official manual for instructions.

When used in dusty environment for a while you might find the MIDI LED flickering although you didn’t touch any of the controls. This is mostly due to dust/fuzz particles in the ‘comb’ at the jog wheels’ underside that is distracting the IR light barriers that detect platter movement. Remove the particles with a vacuum cleaner, or blow into the gap between wheel and housing.

After a few years of heavy usage the buttons and sliders may start to wear out. Then, buttons need to be pressed harder or in a different manner than what was working before, and sliders may send false values when they are actually in the ‘off zone’. Luckily, the buttons are standard parts and relatively easy to replace, and the sliders’ conductive surface can be cleaned with Q-tips and alcohol.

Mapping options

The mapping the following customization variable at the top of the script you can set to your liking:

  • pitchRanges: Set the pitch slider range each time you toggle it.

Just open the Reloop Terminal Mix 2-4.js file in your favorite text editor and you’ll see these variables right near the top. Edit and save and Mixxx will automatically reload the mapping.

Deck controls

The controls are the same on both sides of the controller. The left side controls Deck 1 or 3 and the right side controls Deck 2 or 4.

  • RANGE button - Toggles the pitch slider range. See Mapping Options.

  • KEYLOCK* button - Toggles key lock.

  • POWER LED (red)

  • MIDI LED (blue)

Cross-fader section

Move the cross-fader to smoothly fade between the decks assigned to either side.

Deck assign switches (Terminal Mix 4 only)

Use the four switches on the front of the unit to choose on which side of the cross fader that deck will be heard. (Note that the fader-start functionality correctly follows this assignment.) If “thru” is selected, the cross-fader will not affect the audio from that deck and it will always be heard.

Curve adjust

Use the knob to adjust the curve from a smooth fade to a fast cut.

The remaining controls on the front of the unit adjust hardware parameters and are not MIDI-mappable.
