Glossary of Terms
Algo An algorithm is a set of procedures or formulas that determines the function or behavior of an object. An algo
is the smallest functional part of an algorithm. Think of algos as the building blocks of algorithms—that is, algos
combine to form a complete algorithm. (Where appropriate this manual substitutes the word “function” for algo.)
AMB-5 (IQ–AMB-5) An
ambient sensing IQ mixer with 5 normal mic/line inputs and one sense input. It can
automatically adjust its output level in response to the ambient sound level.
Ambience Background noise or sound.
Ambient Offset The level
below the Gate function Max Gain settings to which the Channel 1 gain will be set
until the ambience level exceeds the Threshold setting. Think of it as an insertion loss.
ASA The
Auto System Activate control located in the control blocks of various IQ components toggles the
operation of all automatic functions on and off. The ASA control is also used to access the sub-block screens where
the automatic functions are configured.
Attack Time The attack time is the speed at which an Input Compressor/Limiter function begins to compress
or limit a signal that is above the Threshold setting. It is labelled “Compression” and can be set to either “fast” or
“slow”.
Atten An IQ P.I.P. control that sets the amount of attenuation at each amplifier input. The attenuator controls
decrease the signal level coming into the IQ P.I.P. only—they cannot add gain to the incoming signal.
Attributes The parameters of a graphic object, such as its color, function, etc.
Auto Level The Auto Level function is available for the SMX-6 and AMB-5 mixers. Unlike the Input Compres-
sor/Limiter function that is designed to handle sudden or transient jumps in input level, the Auto Level function is
designed to control long-term changes in signal level. It helps maintain a more consistent output signal level while
allowing transient peaks to pass.
Aux Most IQ components have an AUX port so non-IQ components can be signalled or turned on and off. When
turned on, +10 VDC is provided at the output of the AUX port. The AUX port circuitry is also capable of sensing
an input signal.
Bar Meter A graphic object that dynamically displays a level (such as an audio input level) with a moving
vertical bar graph. All bar meters have an optional peak hold indicator attribute.
Baud Rate A unit of measure of the transmission speed of a communication system equal to one bit per second.
Turbo supports a transmission speed up to 38,400 baud between the IQ interface and the host computer. The
transmission speed of a Crown Bus loop wired with twisted-pair wiring is 38,400 baud.
Break Detection A feature that automatically reports when breaks occur in Crown Bus loops. It also attempts
to identify the location of a break.
