• 2 independent 12-pole 'Phasor' circuits with depth, feedback and mod source controls
• Dual depth controls on each 'Phasor' circuit, corresponding to both sweep generators
• Arturia's advanced features enhancing the original unit:
• Advanced routing for mono, stereo, series or parallel operation
• 12dB/oct Hi-pass filter on input signal
• ‘Phasor’ poles increased from 6 to 12
• Expression pedal/envelope feature can control LFO rates, ‘Phasor’ circuits
• Stereo reverse option on each ‘Phasor’ module
• Sweep generators can be tempo sync'd
• Individual 'Phasor' circuit bypass and dry/wet controls
• A selection of 37 curated presets for instant iconic modulation sounds

More than just a phase

A simple concept, multiplied, expanded, and pushed to the outer limits.
A definitive sound that was ahead of its time, yet remains hypnotic and otherworldly to this day. Phaser BI-TRON encapsulates the transcendent quality of an undisputed trailblazer of the modulation world. Soft 2-pole flutters, wild asynchronous movement, resonant swirls suspended in orbit - there’s nothing quite like it.

2 SWEEP GENERATORS
It all starts with 2 Independent LFOs, featuring switchable waveforms and rates that can be tempo synced. Tweak both in tandem for unpredictable interplay, resulting in all manner of animated sounds.

DUAL 12-STAGE PHASOR CIRCUITS
As well as 2 LFOs, you get 2 ‘Phasor’ circuits to play with, with independent depth, feedback and modulation source controls.

ANALOG CHARACTER
We analyzed the much-loved tonal nuances of the original pedal, taking extra care to emulate them in great detail for a perfectly authentic response.

MANUAL PEDAL CONTROL
The expression pedal feature lets you manipulate both LFO rates and both Phasor circuits, with the additional option of envelope control.

CHOOSE YOUR ROUTE
Phaser BI-TRON can be run in mono or stereo, series or parallel. This results in an unprecedented stereo modulation palette, each mode offering a distinct sonic character.

PRESETS
A curated selection of 37 presets, giving you instant access to the double-barrelled energy of Phaser BI-TRON.

Rebuilding a legend

The humble phaser was one of the first widely-available guitar effects on the market. Achieved by the relatively simple means of modulating all-pass filters on an input signal, it’s a sound that’s as recognisable as it is divisive. No modulation collection is complete without a phaser - and as the world’s first dual phaser, the Mu-Tron Bi-Phase stood out from the crowd. Popularised by everyone from Smashing Pumpkins to Prince, Kraftwerk to Chromeo, it’s evident that the pull of stereo functionality, interweaving modulation, and analog charm was impossible to resist.

We set about studying, remaking, and enhancing this prized handmade effect. Using our proprietary TAE® technology (True Analog Emulation), we wanted to replicate every subtle detail, every sonic trait - even the control panel and expression pedal functionality. Phaser BI-TRON is every bit an analog dream, primed for your virtual studio.
