Decay Rate (slow, medium, fast) Determines how fast a channel gates off after
hold time expires. Default is medium.
Default meter The input/output displayed on the front panel LED meter when a
input/output meter is not specifically selected elsewhere.
Delay A setting in the Processing window. Delay calculates the amount of signal
delay (up to 500ms) based on the distance between audio source and audience and
the temperature.
Device ID A number which identifies the unit when multiple units of the same
device type are connected in an E-bus network. Because up to eight PSR1212s can
be used in the same network, the device ID range is 0–7.
Device Type A number which identifies the type of unit. For example, a PSR1212
is device type 5.
DSP Digital signal processor.
Expansion bus Consists of two RJ-45 connectors on the rear panel of the
PSR1212. An expansion bus allows multiple PSR1212s to be networked together
using category five twisted-pair (10BaseT) cable.
Expansion bus reference One of the PA adapt reference options. The expansion
bus reference allows you to reference an output on a networked unit.
Filter A device that passes and blocks audio signals based on user-definable
requirements of the system.
•
All Pass A filter that provides only phase shift or phase delay without
appreciably changing the magnitude characteristic. The filter produces a
flat amplitude response. It is useful for matching the delay of two
processing channels with different delays.
•
High Pass A filter that passes high signal frequencies while attenuating
low frequencies. The gain or loss
•
High Shelving Provides boosting or attenuation of frequencies above a
designated frequency. The transition between the spectrum above and below
the designated frequency occurs at a fixed 6dB/octave rate. The gain or loss
above the corner frequency is adjustable to +/–15dB.
•
Low Pass A filter that passes low frequencies while attenuating high
frequencies.
•
Low Shelving Provides boosting or attenuation of frequencies below a
designated frequency. The transition between the spectrum above and below
