Thank you for purchasing 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 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. As an

IQ System

IQ

component, it can be controlled by an

®

, and with its

distributed intelligence™

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 float­ing 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 (Num­ber 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 perfor­mance Output Limiter for system protection.

3 Hardware Installation

The installation of an IQ-USM 810 consists of install­ing the hardware and configuring the unit via IQ for
Windows software. Refer to the IQ for Windows Help
files for instructions in setting up and operating your
IQ software.

The hardware installation is divided into 4 major
steps: 1) connecting to a host computer; 2) connect­ing to the IQ Bus; 3) connecting the audio inputs
and outputs and; 4) connecting auxiliary devices

3.1 Connecting to a Host Computer (Step 1)

An IQ host computer is an IBM® PC-compatible
computer which is used to configure or control/
monitor an IQ System. Depending upon the design
of your IQ System, it may or may not require a host
computer during normal operation.

How the IQ-USM 810 will be used will determine
whether or not it will need to be connected directly
to a host computer. If the unit will be connected to
the IQ Bus it will not need to be connected directly to
a host computer. The following circumstances require
connection to a host computer:

• If an IQ Bus will not be used, the IQ-USM 810 will
need to be connected to a host computer so the
firmware inside the unit can be configured. After­wards, if computer control is not required, the
host computer can be disconnected.

• If the IQ-USM 810 must be configured before it is
installed into an IQ System, it must be connected
directly to a host computer for configuration. The
onboard memory of the unit will maintain its soft­ware configuration without it being plugged into
an AC source.

• If the IQ-USM 810 will be used as an IQ interface
for other IQ System components, it will need to be
connected directly to a host computer for con­figuration of other components during setup, and
for IQ control of components during normal op­eration.

One of the advantages of connecting directly to a host
computer is that a separate IQ interface (

IQ–INT-II

) is
not required. If you plan to configure the unit while it is
connected to the IQ Bus, skip ahead to Section 3.2.

RS232 is commonly used with IBM PCs and com­patibles, and is the communication standard supported
by the IQ-USM 810 when used as an interface. Because
it uses unbalanced signal wiring, it cannot be

Page 10

IQ-USM 810 Reference Manual

IQ-USM 810 IQ Digital Processor / Digital Mixer

used for distances over 50 feet (15.2 m).

The following illustration shows how to wire the
serial cable:

Figure 3.2 RS232 Cable Wiring

Important: Do not use twisted pair wire for RS232
because it increases crosstalk. Instead, use an un­twisted cable or ribbon cable.

Baud rate for RS232 serial communication is set using
the front panel buttons shown in Figure 2.1. IQ for
Windows software has the capability to adjust auto­matically to the baud rate of the IQ-USM 810 for maxi­mum performance, so setting the baud rate usually is
not necessary; however, the baud rate can be set by
using the following procedure:

3.1.1 Set the Baud Rate

To set the baud rate, push and hold the front-panel
SEL button (see Figure 2.1) until the display
changes first to address select mode, then to baud
rate select mode, Then push the up or down arrow
buttons to select the desired baud rate. The highest
baud rate supported by the unit is 115 K baud.*

When the SEL button is released, the user has two
seconds to begin using the up or down arrow
buttons before the display changes back to de­fault. When the parameter is adjusted to the

desired value, press the SEL button again to
store the setting.

The communication parameters of the host com­puter are set within IQ for Windows software. Please
refer to the IQ for Windows Help files for information
about setting up communication parameters.

Here are some steps to follow if you are having
difficulty establishing serial communication:

• If the host computer fails to communicate with the
unit and the communication standard and pa­rameters are set correctly, try reducing the baud
rate.

• Check the serial cable for improper wiring or pos­sible shorted or broken wires.

• If communication problems persist, check for
other programs or hardware in the computer that
might interfere.

• For further assistance contact the Crown Techni­cal Support Group (see Section 7 for contact in­formation.)

3.2 Connecting to the IQ Bus (Step 2)

The IQ Bus is a serial communication loop for
transmiting IQ commands and data. It provides excel­lent flexibility, allowing an IQ Bus loop to be wired with
either fiber optic cabling or with inexpensive twisted­pair wire. A single IQ System can have more than one
IQ Bus loop. To function properly, an IQ Bus loop must
be unbroken.

By giving every IQ component a unique address per
IQ loop, each can be individually controlled and
monitored.

3.2.1 Set the IQ Address

To set the address, push and hold the front-panel SEL
button (see Figure 2.1) until the display changes to
address select mode, then push the up or down but­tons to select the desired address number. Press the
SEL button again to store the address. The display
will automatically return to preset display mode in a
few seconds.

An IQ address can be any number from 1 to 250.* No
two IQ components of the same type which are con­nected to the same IQ Bus can have the same ad­dress. Suppose, for example, an IQ System has two IQ
Bus loops, 1 and 2, and a IQ-USM 810 is to be in­stalled into loop 1 and given an address of 114. No other
IQ-USM 810 can be given the same address in loop 1.
However, a IQ-USM 810 in loop 2 can have the address
of 114, and another type of IQ component can be given
an address of 114 in loop 1. For example, both an

PIP-USP2

and a IQ-USM 810 can use address 114 in

loop 1 or any other loop.

* In most cases, 115 K baud is the best setting. Adjust to a lower baud rate

only if you are having difficulty establishing communications with the host
computer.

* Other IQ components can be set to addresses above 250, but do not do so,

because numbers above 250 are reserved for special use. With the IQ­USM 810, address “0” (zero) disconnects external communication.

3.2.2 Connect the IQ-USM 810 to the IQ
System via the IQ Bus

The IQ components in an IQ Bus loop are wired se­quentially. The loop begins and ends with the IQ inter­face. The output of one IQ component “loops” to the
input of the next and so on as shown in Figure 3.9.

Three different types of connectors are used for IQ Bus
wiring on IQ components. These include DIN connec­tors, RJ-45 connectors, and removable barrier strip
plugs. The IQ-USM 810 uses RJ-45 connectors that
accept plugs like the one shown in Figure 3.3.

3.3 Connect the Audio Wiring (Step 3)

The IQ-USM 810 has eight mic/line inputs, two main
outputs and eight AUX outputs Three-terminal remov­able barrier block connectors are provided for the mic/
line inputs and main and AUX outputs. See Section 6.1
for information on the operation of the IQ-USM 810
inputs and outputs.
