1.2 The IQ-USM 810
The Crown IQ-USM 810 is an 8x10 mixer/processor that provides unique dual input processing paths. As an IQ® component, it can be controlled by an IQ Sys- tem®, and with its distributed intelligence™ capability, continue to operate even when an IQ System is not connected. The IQ-USM 810 can also act as a sys- tem interface to other IQ components.
The IQ-USM 810 features high-quality 24-bit A/D and D/A converters along with 240MIPS of full 32-bit float- ing point DSP for optimum dynamic range.
The dual input processing paths include a full comple- ment of signal processing features, including ad- vanced algorithms for gating, auto-leveling, filtering, compression and automixing.
A full 8x8 Matrix Mixer allows any combination of rout- ing and mixing from any input to any output. The Ma- trix Mixer outputs are routed to the two Main Audio

Outputs and eight AUX Audio Outputs. The Main and AUX Audio Output sections further process the sig- nal with individually adjustable signal delay and fil- ters along with an Ambient-Leveler and a high perfor- mance Output Limiter for system protection.
A Multi-Function Control Port implements analog and digital I/O for control and monitor by simple potenti- ometer and switch wall controllers and indicator pan- els.
All of the IQ-USM 810 parameters are backed up via reliable FLASH memory. System configurations may be stored for recall from any of thirty-two system pre- sets from the front panel control or via IQ for Windows software.
