Reference Manual

1 Welcome

Thank you for purchasing the

Crown

IQ-USM 810. The

IQ-USM 810 is a true 8x10 mixer that also provides
very unique dual input processing paths, making it two
complete eight-channel mixers in one chassis. In addi-
tion, every input and output channel includes a full
complement of signal processing as well as auto-mix-
ing features to offer a complete “system-in-a-box” solu-
tion. As an

component, it can be controlled by an

IQ System

, and with its

distributed intelligence™ ca-

pability, continue to operate even when an IQ System is
not connected. The IQ-USM 810 can also act as a
system 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.

Each of the eight balanced inputs is fully adjustable for
any mic- or line-level source and is processed through
adjustable signal delay and filtering before being split
into the two separate “A/B” Processing Sections. The
A/B Processing Sections include advanced algorithms
for gating, auto-leveling, filtering, compression and
automixing. Automixing functions include NOM (Num-
ber of Open Mics) Attenuation, Priority Ducking, and
Adaptive Gating processing. Each of the sixteen A/B
Processing Sections is then processed by a full 8x8
Matrix Mixer that allows any combination of routing and
mixing from any input to any output. The Matrix Mixer
outputs are routed to eight AUX Audio Outputs. The
Main and AUX Audio Output sections further process
the signal with individually adjustable signal delay and
filters along with an Ambient-Leveler and a high perfor-
mance Output Limiter for system protection.

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 presets
from the front panel control or via

IQ for Windows

software. The unit is controllable by IQ for Windows
software (version 4.1 or later) via IQ Bus, standard RS-
232 serial port, or over Ethernet (with

IQNET Server

software). It may also be controlled by third-party sys-
tem controllers from companies such as AMX and
Crestron. A Multi-Function Control Port implements
analog and digital I/O for control and monitor by simple
potentiometer and switch wall controllers and indicator
panels.
