Multi Stereo Line Mixer
The Multi Stereo Line Mixer (MSLM) is the ultimate control center for your rack system — a full-featured splitter, mixer, and switcher designed for professional guitarists, studio engineers, and touring musicians.
It brings together everything rack users have dreamed of for decades: total signal flexibility, MIDI control, and pristine analog tone — all in a 1U rack.
Far more than a traditional line mixer, the MSLM acts as the brain of your rig, combining serial and parallel processing paths, auxiliary routing, MIDI automation, and transformer-isolated outputs for perfect signal integrity.
It can manage up to five stereo effects loops simultaneously, allowing both classic parallel configurations and advanced “3+2” hybrid routing, all switchable in real time from the front panel or via MIDI Control Change.
Three serial loops (L1–L3) handle compressors, EQs, or choruses in sequence, while three parallel loops (FX1–FX3) and two auxiliary loops (AUX1–AUX2) let you create complex routing like delay-into-reverb or multi-wet setups — without touching a single cable.
A dedicated dry path preserves your unprocessed tone at all times, and a transformer-isolated Dry Out makes wet/dry/wet rigs effortless.
With four MIDI-assignable function switches, balanced XLR outputs, and phantom power injection for your MIDI controller, the MSLM redefines what a modern rack mixer can do.
Every unit is handcrafted in Italy, built for the tone purist who refuses to compromise.

I use it for my wet dry wet setting and parallel effect. It does the job well.
Dà la sensazione di un apparecchio professionale. Non sembra un compromesso da pedaliera adattato al rack.
It’s a product you’ll appreciate if you already have a complex rig. In my case, it solved several problems at once.
Con il MIDI riesco a richiamare configurazioni diverse senza toccare cavi o livelli. E’ veramente ben studiato.
It’s really made my life easier. I’m probably one of the few people who still plays live with a rack full of effects, but the MSLM has kept me going—in fact, I’m happier than ever to use my effects.
Delay and reverb work best when used properly. With this mixer, the final sound is fuller and cleaner.
Good old Bradshaw set the standard, but this is on a whole other level. A 1U rack unit, 8 stereo effects, and full MIDI support. Well done, RedSeven.
Averlo avuto 40 anni fa, sarebbe stato incredibile. Sembra un oggetto fatto per essere utilizzato in quei rig di L.A. anni 80.
L’ho preso soprattutto per gestire meglio il wet dry wet. Finalmente ho un routing stabile e senza soluzioni improvvisate. Qualità sonora e semplicità d’utilizzo disarmante.
What I noticed is that the dry signal remains intact. The effects are there, but they don’t overpower everything else. It’s truly an incredible result, considering it handles 8 stereo effects.
Antes, con ciertas combinaciones, tenía que hacer concesiones. Ahora lo organizo todo de una forma mucho más clara.
I had too many cables lying around. With this mixer, the setup has become much neater and easier to manage.
