PHASE
When a signal is out of phase with another signal, it can cause cancellation, which (as its name implies)
results in something missing. The opposite is true when two signals are in phase; the combined signals
can be solid or absolutely overpowering, depending on the sounds and how "in phase" they are. Using
the phase relationship between two sounds can be a powerful tool for fighting feedback or making
multiple sound sources (such as a pickup and a built-in microphone) sound better together.
The Phase switch can accomplish a couple of different things. If you are using an acoustic instrument
such as a guitar equipped with only one pickup or internal microphone, it inverts the signal's phase,
which can be a remedy for feedback in some cases. If your instrument has a built-in mic as well as a
pickup, one of the signals may be out of phase with the other, creating a nasal sound or other symptoms
of signal cancellation. Employing the Phase switch when treating one of the signals with the Dual
Parametric D.I. before mixing it with the other signal at a mixer can provide a stronger signal, often with
better tone.
Regardless of what type of signal you are sending through the Dual Parametric D.I., try the Phase switch
in both of its positions, to be sure the best sound is being produced.
BAND ONE
Band One and Band Two are identically configured. Therefore, all
information pertaining to the controls and functions of Band One
are also applicable to Band Two.
OUT / IN SWITCH
This switch allows you to activate or bypass Band One's
parametric equalizer. Because both Bands are outfitted with an
Out/In switch, you may set up two separate equalization schemes
with the Dual Parametric D.I., and select either, both, or neither.
The switch is also helpful when you want to compare the effect of
the D.I. against the straight (bypassed) sound.
When the Band One and Band Two Out/In switches are both in the
OUT position, then both EQ sections are bypassed. Note, though,
that the Volume control is still active, and the signal is still
buffered-that is, its impedance is isolated from that of anything
connected to the Dual Parametric D.I.'s output. This "double-
bypassed" mode, therefore, makes the Dual Parametric D.I. an
impedance-buffered direct box, perfect for studio recording and
interfacing instruments with P.A. mixers, even when you don't need
to alter their tone.
