PPM/Peak Program Meter A peak oriented type of volt meter system
designed to detect signal overloads easily. A PPM responds to input signals
very quickly, several times faster than a Volt Unit meter.
peaking. A broad band equalizer process used to increase or decrease a wide
band of frequencies. The DA7 equalizer has 4 Q controls per input fader
to adjust the frequencies affected from broad to narrow.
Phase. Signal connections. In-phase is a properly wired connections; signals
can be mixed (added) to other signals. Out-of-phase is a connection that
is reversed and causes cancelation of the signal to occur when mixed with
other signals.
Phantom power. A method of sending power to certain microphones over
standard balanced lines.
Phone Jack. A 1/4” connector used in audio. The DA7 uses two types. The
Tip Sleeve (TS) for single signal connections and the Tip Ring Sleeve
(TRS) for dual signal connections. The Tip Ring Sleeve connectors are
normally used for stereo pairs, or balanced signals where there is a plus,
minus, and ground.
Phono Jack. A connector used on consumer and semi-professional audio
and video equipment originally known as the RCA jack. Also used for
digital signals (S/PDIF).
Pink Noise. A specific type of random noise with an equal amount of energy
per octave. White Noise is random noise with an equal amount of energy
per frequncy band.
Post Fader. A point in the signal path after a fader. The DA7 allows for both
pre and post fader insertion. See Pre Fader.
Pre Fader. A point in the signal path before the fader. The DA7 allows for
both pre and post fader insertion. See Post Fader.
Program Change. MIDI command sent to MIDI devices to change the patch
or settings.
Punch In/Out. The DA7’s automation controls allow Punch In/Out
recording.
Q. The “quality” of a filter. A low Q affects a broad band of frequencies, while
a high Q affects a narrow band of frequencies. On the DA7, Q is one of
the parameters that can be controlled with the 4 band parametric
