3 Installation

Before beginning, please carefully note:

CAUTION: STATIC ELECTRICITY MAY DAMAGE THE IQ–P.I.P.–DSPMODULE. Use caution when handling the unit. Carefully ground yourself BEFORE touching the IQ–P.I.P.–DSPmodule. For added safety, touch the outer metal collar of either Crown Bus connector (see Figure 2.1). This should safely discharge any static electricity through the ground plane of the module. Avoid unnecessarily touching the components, edge connector or solder pads on the circuit boards.

NOTE — Amplifier Compatibility

The version of the IQ-P.I.P.-DSPcard you received will vary depending on whether you indicated the card will be installed on a PIP2-compatible amplifier (such as the Crown MA-5000VZ or CT-10 Series amplifiers). The correct card to install in a PIP2-compatible amplifier is the IQ-P.I.P.-DSP-PIP2. The standard IQ-P.I.P.-DSPshould be ordered for non-PIP2-compatible amplifiers.

Should you later wish to change the amplifier you are using for your IQ-P.I.P.-DSPinstallation, it is possible to alter the card's configuration by simply removing or installing two SIPS from the card’s circuit boards1. For instructions on installing or removing these SIPS, contact Crown Technical Support.

1.Set the IQ address switch SW1. By giving each IQ component a unique address, it can be individu- ally controlled and monitored. Whenever the IQ System wants to send a command to just one IQ component, it first sends its address and then the

is used to set the IQ address of the IQ–P.I.P.– DSP. No two IQ components of the same type which are connected to the same Crown Bus can have the same address. Suppose, for ex- ample, an IQ System has two Crown Bus loops, 1 and 2, and this IQ–P.I.P.–DSPis to be installed into loop 1 and given an address of 77. No other IQ–P.I.P.–DSPcan be given the same address in loop 1. However, an IQ–P.I.P.–DSPin loop 2 can have the same address.

Different IQ components in the same Crown Bus loop can have the same address. For example, both an SMX-6mixer and an IQ–P.I.P.–DSPcan use address 77 in the same loop.

A valid IQ address is any number from 1 to 250. Do not use a number higher than 250 since they are reserved for special use. An address of “0” (zero) should never be used except to put the IQ–P.I.P.–DSPinto a stand-alone mode where it is invisible to the IQ System and acts as a

“dumb” balanced audio input.

Switch SW1 is located on the right side on the underside of the top circuit board (Figure 3.1). It has eight segments because it actually contains eight tiny switches inside. There is an arrow printed on the switch along its left side that points to the “ON” position and the switches are numbered along the bottom (Figure 3.2).

Each of the eight switches in SW1 has a value which doubles as the switch number increases. For example switch 1 has a value of 1; switch 2 has a value of 2; switch 3 has a value of 4; switch 4 has a value of 8 and so on.

The address is determined by adding the values of all “ON” switches. In Figure 3.2 switches 1, 3, 4 and 7 are on. Simply add the values to find the address: 1+4+8+64=77.

A convenient series of IQ address tables are in- cluded in Section 7. The tables show the switch
