Shielded wire will reduce the total distance a Crown Bus loop can be run, but shielding may be neces- sary to reduce interference with certain kinds of audio cables.
Page 10 IQ Mixer / Multiplexer Hardware Installation Rev. 0 3 Hardware Installation The installation of an IQ mixer/multiplexer consists of two major parts: installing the hardware and con- figuring the software. This manual deals only with hardware installation.

Here’s how to wire the cable: while it is connected to the Crown Bus, skip ahead to Section 3.2. There are two main communication standards sup- ported by the unit for serial communication with a host computer.

Suppose, for example, an IQ System has two Crown Bus loops as shown in Figure 3.1 and an SMX-6 is installed in loop 1 and given IQ address 77. No other SMX-6 can be given the same address in Crown Bus loop 1.

Slide it to the right (P) to provide 44 VDC to mics requiring phantom power. Each input has a screwdriver-set, calibrated gain control to compensate for different input source levels.
