Behaviors

Line Input to Patch signal at rear BAL-IN or UNBAL-IN

External line-level audio (from mixer, FX unit, synth, etc.) enters via rear connectors, gain-adjusted by the Input Gain Switch, and appears at EXT L/R patch points on the front panel.

Patch to Line Output signal at MAIN IN

Eurorack audio patched into MAIN L/R is attenuated by the Main Output Level knob and sent to the rear balanced (BAL-OUT) and unbalanced (UNBAL-OUT) connectors for connection to mixers or interfaces.

Cue Monitoring signal at CUE IN

A cue feed patched to CUE L/R can be monitored through headphones (HP Switch = CUE) independently of the main output, or summed with the main output (Module Out Switch = CUE+MAIN).

Headphone Monitoring headphone plugged in

Headphone output has its own level control and source selection (CUE or module OUT). Also feeds the rear PHONES-OUT connector for use with compatible Intellijel modules.

Controls

EXT Input Input Gain Switch Sets gain for the EXT OUT patch points from rear-panel line input.
Down = 0dB · Up = +6dB · Mid = +20dB
Headphone HP Monitor Switch Selects headphone source: CUE input only, or module OUT only.
Left = CUE In · Right = Module Out
Main Output Module Out Switch Sets module output source: CUE + MAIN summed, or MAIN only.
Left = CUE + MAIN · Right = MAIN only
