Crown Introduces the IQ-USM 810
 February 4, 2000
The Crown IQ-USM 810 is an eight-input/ten-output
digital mixer that uniquely provides dual input processing paths, making
it two complete eight-channel mixers in one 2U chassis. In addition, every
input and output channel includes a full complement of signal processing
as well as auto-mixing features to offer a complete 'system in a box'
solution for an infinite range of applications, including auditoriums,
churches, public transportation centers, restaurants, retail stores and
sports facilities.
"The IQ-USM 810 is truly a unique audio control device," says Jim
Stembel, IQ product manager. "Its versatile feature sets allow contractors
to not only reduce the number of products installed into a sound system, but to
greatly reduce the cost as well."
Each of the eight balanced barrier connector inputs is fully adjustable for
any mic-, mic (with phantom)-, or line-level source and is processed through adjustable
signal delay and filtering before being split into the two separate A/B Processing
Sections. Each section include advanced algorithms for gating, auto-leveling,
filtering, compression and auto-mixing. Auto-mixing functions include NOM (Number
of Open Mics) Attenuation, Priority Ducking, and Adaptive Gating.
Each of the 16 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 output.
The Matrix Mixer outputs are routed to eight AUX Audio Outputs. The Main and AUX
Output sections further process the signal with individually adjustable signal
delay and filters along with an Ambient-Leveler and a high performance Output
Limiter for system protection.
The IQ-USM 810's connectivity makes it extremely versatile. The unit is controllable
by free 'IQ for Windows' software (http://www.crownaudio.com) via Crown's two-wire
IQ Bus, standard RS-232 serial port, or over Ethernet (with 'IQNET Server' software).
It may also be controlled by third-party system controllers from companies such
as AMX and Crestron. With its distributed intelligence capability, the IQ-USM-810
can even continue to operate when an IQ System is not connected. It also functions
as an IQ system interface (IQ Bus) eliminating the cost of a separate IQ interface.
Crown's IQ Software is easy to use and navigate. Compatible with Microsoft
Windows 95/98 and NT, the software is completely object-based and is configured
to follow the signal flow in the IQ-USM 810.
All of the IQ-USM 810 parameters are backed up via reliable FLASH Memory. System
configurations may be stored in any of 32 user-definable preset locations, then
recalled with front panel controls, switch closures, or the 'IQ for Windows' software.
Preset changes can also be scheduled from the IQ-USM 810's internal real-time
clock/calendar. An internal 'segue' feature allows elegant transitions with user
programmable fade rates between system presets.
The IQ-USM 810 can be easily configured for automatic room combining as well
as simple-to-use wall station controls. 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.
The IQ-USM-810 utilizes high-quality 24-bit A/D and D/A converters along with
240MIPS of full 32-bit floating point DSP to offer over 100 dB of dynamic range.
The unit is also equipped with a Cobranet-ready expansion slot for future use
to route and control multiple digital audio channels via standard Ethernet network
components.
A true universal power supply allows the unit to accept 100-250 VAC at 50-60
Hz with automatic switch-over between voltages.
