What About The Phaser Bi-Tron - Arturia Phaser BI-TRON User Manual

1.2. What about the Phaser BI-TRON?

The Arturia Phaser BI-TRON is part of a new set of effects, proposing three new iconic
vintage modulation effect units.
The original unit this plug-in is modeled on is one of the most popular analog phaser pedals
that appeared during the seventies. Released in 1974, it was a sophisticated dual phaser
device, combining two independent six-stage phase-shifting circuits with multiple ways of
being controlled. This means it is capable of quite some powerful phasing effects, and more
powerful than two individual phaser units combined, due to the interactions made possible
by its dual engine configuration. It was also the first phaser to include a feedback control
for deeper phasing.
The unit features two independent low-frequency oscillators, and can be controlled through
pedals or other external inputs. Besides this, the fact that it has 2 independent circuits allows
for true stereo, which was another factor that contributed to it being selected as the phaser
unit to be emulated.
Among it's famous users we can find names like Stevie Wonder, Grateful Dead, Smashing
Pumpkins, and Lee Scratch Perry (dub).
The unique design of this phaser adds to its appeal, and today the available units may reach
far more expensive prices than most of the other vintage guitar pedals.
But that's not all. As usual, Arturia Phaser BI-TRON come with an additional "pedal", which
can be selected as an alternate source of modulation. The pedal has a manual control and
an envelope follower. Other advanced features are an hi-pass filter and the possibility to
control the number of poles of the all-pass filter independently for each of the two circuits
(from 2 to 12).
Finally, there's the possibility to phase-reverse the output of the phaser.
