Q A number that describes the damping or, conversely, the resonance of a system. It is often used to describe the
ratio of a filter’s center frequency to its bandwidth.
Ratio The Ratio or Compression Ratio parameters are used in both the Input Compressor/Limiter and Output
Compressor/Limiter functions. They set the amount of compression that will be applied for every step over the
Threshold. For example, a ratio of 4:1 will cause 15 dB of compression to be applied to a signal that is 20 dB over
the Threshold. An infinite compression Ratio (
∞:1) will cause the function to behave like a limiter. See Compres-
sor, Limiter and Threshold also.
Reaction Time An Auto Level function parameter that determines how quickly the gain will be adjusted so the
average signal level matches the Threshold setting.
Release Time An Input Compressor/Limiter parameter that sets the amount of time it takes for the gain to
return to normal when the input level drops below the Threshold setting.
Roll Call The IQ program performs a roll call to establish communication with all IQ components in an IQ
System and to upload all system settings.
RS232 A serial communication standard supported by most PCs. It uses unbalanced signal wiring and should
not be used for distances over 50 feet (15.2 m).
RS422 A serial communication standard supported by Macintosh computers. It uses balanced signal wiring and
can be used for distances up to 2,000 feet (610 m).
Sel A Select control, found in most control blocks, that is used to select one or more IQ components. The GDMs
of selected IQ components are automatically displayed on a graphics plate when the graphics plate Display
control is set to “Selected”. This avoids the tedium of manually placing GDMs onto a graphics plate. In the amplifier
control blocks, Sel also selects which amplifiers will be displayed in the Display Screen. See Display Screen also.
SLM-8 (IQ–SLM-8) A
system and load monitor with eight channels that can monitor the impedance response
of a load (such as a loudspeaker) and the frequency magnitude response of any line-level or high-level output.
Although it requires a host computer to be configured, it can also function in a stand-alone mode.
SMX-6 (IQ–SMX-6) A
sensing mixer with 6 mic/line inputs and two separate output channels. With its automatic
functions, it can serve as a programmable automatic mic mixer.
Software The programs that run in the “memory” (RAM) of a computer or processor. The IQ-MSD program
is software.
Solo A feature that enables all amplifiers to be turned off except one. This is a very handy setup and
troubleshooting feature.
Spin Control A graphic object that is often used to control multistate parameters that cannot be controlled by
a Pot or Button object (such as the Delay Time parameter of an SMX-6 Gate function). It has a text/numerical
readout and an increment and decrement button to make selections.
