The MRX-12 and MRX-12S have 12 single high-current single-pole, single-throw (SPST) relays.
Mute An IQ P.I.P. control that turns the input of each channel on or off. The “off” position sets the input attenuators
to their maximum value (–50 dB).
ODEP An indicator in the amplifier (IQ P.I.P.) control blocks that shows the status of the Output Device Emulation
Protection circuitry for each channel. It displays the percent of thermal-dynamic energy reserve that is presently
being used by the amplifier. If 100% has been consumed, ODEP limiting will begin to protect the amplifier.
Offset The Offset, listed at the bottom of the Control Block screens, indicates the position of the control block
where the cursor is presently located. Its position is referenced from the top or first control block. For example, the
first control block is Offset 1, the second control block is Offset 2, the third control block is Offset 3, and so on.
On Line An IQ component is said to be “on line” when it is in communication with an IQ System. Most IQ
components communicate with the system via the Crown Bus.
Open to Idle Gain Setting the Auto Leveler Gate Function of the Auto Level function to the “Open to Idle
Gain” causes the function to set the gain to the Idle Gain setting when the gate first opens.
Open to Last Position Setting the Auto Leveler Gate Function of the Auto Level function to the “Open to Last
Position” causes the function to ignore the Idle Gain setting when a gate first opens. Instead, the gain is set to its last
level just before the gate closed.
Peak Hold An option of the bar meters and graphic display modules that causes the peak levels displayed by
the level meters to persist long enough (with a thin line) to be easily observed.
P.I.P. A
Programmable Input Processor is a module that plugs into the back of a Crown P.I.P.-compatible amplifier.
Many P.I.P.s are available to provide a variety of features such as sophisticated error-driven compressors,
crossover networks, voice-over paging, constant-directivity horn equalization, digital signal processing, IQ
System connection, and much more.
Plotter Object A specialized container object that is used to display curves from an SLM-8 on a graphics
plate. See Curve object also.
Pol An IQ P.I.P. control that can be used to invert the
polarity of the audio signal.
Pot A graphic object that acts like a level control or
potentiometer. For example, it can be used to control the input
attenuator of a Crown amplifier equipped with an IQ P.I.P. or the gain control of an SMX-6.
Power An IQ P.I.P. control that turns on and off the high voltage power supply of each channel.
