1 Welcome

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

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.

IQ-

* 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.

IQ-USM 810 Reference Manual

* 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.

Page 11

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.
