PIP-USP4 Module

PIP-USP4 Image

The Crown® PIP-USP4 is a 4th generation DSP-based PIP™ (Programmable Input Processor) input module for CTs Series two channel amplifiers. The USP4 connects to an Ethernet network allowing it to be remotely controlled and monitored via System Architect. In addition, the USP4 allows the transport of real-time digital audio via CobraNet™.

The USP4 is a HiQnet™ series component and connects to the audio control/monitor network using 100Mb* Ethernet hardware (switches, Network Interface Cards, and cables). The audio signal is available over the same 100Mb* Ethernet network, providing a simple to install, single plug solution for audio distribution, control, and monitoring.

The USP4's OMNIDRIVEHD™ processor gives the user an enormous amount of digital signal processing. LevelMAX™ limiters, proprietary FIR and IIR filters, audio routing, faders, meters, polarity & mute, compressors, delays, error reporting and load monitoring are all available. Built in noise and sine-wave generators provide noise masking and test capabilities. The enhanced AUX port allows users to interface with the USP4 to provide additional external control and monitoring.

Offering crisp clear sound and the widest dynamic range possible, the PIP-USP4 provides unprecedented power and flexibility in one compact – and very affordable – module.

The USP4 can be installed in any CTs two channel amplifier. The USP4 is available with CobraNet™ for digital audio transport.

The USP4 requires HARMAN Audio Architect software. The software is available at hiqnet.harmanpro. com. For more details about the Crown PIPUSP4- CN, contact the Crown Technical Support Group here.
