Instruction Manual

Operation
By today’s standards, the Bi-Phase is not a terribly complicated signal processor. It has no presets, no MIDI
control, no digital displays, no memory cards, and never needs firmware updates. For the sake of historical
perspective, though, we’ll reproduce a passage from the introduction of the Bi-Phase’s manual:
The Mu-Tron Bi-Phase is a sophisticated and versatile sound modification device which consists of two
independent six-stage phase shifters. Both phasors have complete control flexibility, and this,
combined with some sophisticated switching and control functions, gives the musician an extremely
wide range of effects including many that are simply not possible even with two conventional phasors.
However, this same total flexibility means that there are quite a few controls the user must become
familiar with before he masters the operation of the Bi-Phase. The musician who takes the time to
study this manual and learn the functioning of each control will be well on his way toward
understanding the subtleties of the Bi-Phase.
[Yes, they really did use the word “sophisticated” twice in as many sentences.] PhaseTwo’s controls reproduce
those of the Bi-Phase almost exactly, and while PhaseTwo’s operation is no more (or less) complicated than
that of the Bi-Phase, we will describe each of its controls below.
The Controls
PhaseTwo’s onscreen controls are laid out in
the same arrangement as the Bi-Phase’s
knobs and switches. The controls are
grouped by their function, and the groups
are delimited with rounded-corner boxes.
Each box can be thought of as a functional
unit or module within PhaseTwo; the name
of the unit appears at the top of the box.
The modules and their controls are
described below. The orange numbers on
the picture correspond to the numbers at
the beginnings of the following paragraphs.
