IQ–P.I.P.–DSPProgrammable Input Processor with DSP for IQ Systems

Fig. 1.1 IQ–P.I.P.–DSP

1 Welcome

The IQ–P.I.P.–DSPis a powerful IQ component that con- nects an IQ-compatible amplifier to the Crown Bus of an IQ System so the amplifier can be controlled and monitored. Its DSP (digital signal processing) capabili- ties enable it to offer a variety of programmable func- tions, such as filters and crossovers, signal delay, input compressor and output limiter and a variety of other useful features similar to those included with our other SmartAmpIQ P.I.P.s. The module is powered by the amplifier (an external AC power adapter may be re- quired with certain amplifiers).

The IQ–P.I.P.–DSPis a PIP2 input module for Crown P.I.P.® (programmable input processor) and PIP2-com- patible amplifiers. Because it is also an IQ2-series com- ponent, it supports Crown’s UCODE protocol and requires an IQ System® with an IQ2-compatible IQ in- terface. UCODE (universal code) enables users and third parties to develop custom software objects to con- trol and monitor IQ2-compatible components like the IQ–P.I.P.–DSP.

To ensure fast and accurate processing, the IQ–P.I.P.- DSP features two separate onboard processors. A Motorola 6811 microprocessor inside the P.I.P. over- sees communication with the IQ System and most SmartAmp features (similar to an IQ–P.I.P.–SMT). A Motorola 56002 microprocessor handles all digital sig- nal processing.

Each IQ–P.I.P.–DSPis easy to install and includes an IQ address switch, allowing the unit to have a unique ad- dress on the Crown Bus. Its error-tolerant design en- ables it to automatically reset itself if noise “spikes” or other disturbances are encountered.

This manual will help you successfully install your unit. We strongly recommend you read all the instructions, warnings and cautions contained within. Also for your protection, please send in the warranty registration card today and save the bill of sale since it is your official proof of purchase.

1.1 Unpacking

The unit is shipped in a protective antistatic bag.

CAUTION: STATIC ELECTRICITY MAY DAMAGE THE UNIT. Use caution when handling the unit. Carefully ground yourself BEFORE touching the unit. For added safety, touch the outer metal collar of either Crown Bus connector. Avoid unnecessarily touching the components, edge connector or solder pads on the circuit boards.

Please unpack and inspect the unit for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you, the consignee, may initiate a claim with the carrier for shipping damage. Crown will be happy to cooperate fully as needed. Save the shipping carton as evidence of damage for the shipper’s inspection.

Even if the unit arrived in perfect condition, as most do, save all packing materials. NEVER SHIP THE UNIT

WITHOUT THE FACTORY PACK.
