Number of Open mics (NOm)/Constant gain mode
Adjusts the output level based on the number of mics gated on and routed to an output.
Off Attenuation
The amount of level reduction a microphone is given when the microphone is not gated on.
PA Adaptive mode
The Converge Pro 880/840T recognizes how much loudspeaker audio is picked up by the microphones and then uses
this level as the new ambient level when audio is present at the power amplifier. This prevents loudspeaker audio from
gating ON a microphone, while still allowing people in the room to gate on microphones as they speak.
PA Adaptive reference
This Converge Console setting determines which output (typically for a loudspeaker) is used as a reference for an input.
Paging Zone
A subset of a paging system. Intended to isolate paging system outputs to specific areas.
Parametric equalizer (PeQ)
A multi-band variable equalizer with control of gain, center frequency, and bandwidth. A properly configured PeQ
enables the Converge Pro to offset speaker or room acoustic deficiencies.
Phantom Power
Supplied by the Converge Pro to power most condenser microphones. The Converge Pro provides 24 volts of phantom
power. This feature can be switched off for devices not requiring phantom power.
Phase Plot
A plot of phase angle (-180 to 180 degrees) vs. frequency (20Hz to 20kHz) on a logarithmic scale.
Pink Noise
An audio test signal containing all the frequencies in a given audio spectrum, with equal energy in each octave.
Preset
One of 32 configurable memories in a Converge Pro. A preset can be programmed with a variety of routing, level, gating,
delay, filter, and equalizer settings to meet specific application requirements.
Preset mask
Defines whether a contact closure activates on a low or high signal on the rear panel of the unit.
Q Quality factor
It is the ratio of the center frequency divided by the bandwidth. Q reflects an inverse relationship to the bandwidth, and
adjusts from .02:1 to 40:1 on a Converge Pro.
ratio
The amount of compression applied to the output signal compared with the input signal as the signal exceeds the
threshold level.
release
Release is a parameter which determines how quickly compression is released after the input signal drops below the
threshold.
reverberation
A diffuse acoustic energy field fed and maintained by sound reflections from the room surfaces .
serial Command
A bit description designed to execute an instruction or command.
signal Delay
Used for:
Compensating for physical placement of multiple drivers in a cluster—to align points of acoustic origin in the 1.
same plane.
ensure matching arrival times at listeners from multiple loudspeaker drivers.
2.
Using the Haas effect to maintain localization of the source, even with a distributed system. 3.
