made in durable aluminium, with pu syntethic leather backing and custom made knobs and faders.
beyond being a mixer, it’s also a usb audio interface, has a built-in synthesizer and sequencer, and much more.
the main control and navigation centers around the select knob and button, with all functions displayed on the compact oled screen.
this guide takes you through the layout, connectivity, various modes and general functions of your TX–6.
the audio inputs are located on the top side of the unit.
the usb type c port can be used as a multi channel audio interface, as well as for midi control, firmware updates, stereo recording and charging.
there are six 3.5 mm stereo mini jack input sockets, all of which can be individually configured as mono, stereo or split L+R, in any combination.
this means you can easily connect as much as up to
6 stereo sources, or even
12 mono sources, shared across the six physical inputs.
the audio outputs are located on the bottom side of the unit.
there are three sockets consisting of one 3.5 mm stereo mini jack for aux out,
another 3.5 mm headset,
and mic mini jack for cue out, and one 6.35 mm stereo jack for main out.
main out fits an included and removable 6.35 mm stereo jack to 3.5 mm mini jack adapter.
connect your audio sources into the TX–6 audio inputs.
units such as pocket operators, OP–1, OP–Z or any other line level sources can be used. pocket operator modular should be connected via its speaker output. guitars and microphones may need a preamp to function well.
cue out directly accepts a headset microphone, such as the M–1.
usb can also be used for audio input, in addition to midi control, firmware updates and charging.
the various outputs on
TX–6 can be connected to headphones, studio monitors, pa speakers or other audio equipment.
main out is used for the main audio output signal.
aux and cue out can be used for monitoring and recording, as well as for creating effect loops and sending sync.
