PIP-USP3 (discontinued)

IQ DSP Programmable Input Processor

PIP-USP3 is a DSP-based PIP module that integrates into a 100-Mb Ethernet network via TCP/IQ protocol. An extremely versatile speaker-processing unit that mounts right in your Crown amplifier, this compact module greatly reduces the costs of typical audio systems while eliminating the rack space needed for signal processing. Offers up to thirty-two filters per channel as well as load supervision that continuously monitors the load impedance using the signal source as the test signal. Also includes compressors, limiters, error reporting, ten internal presets, up to 2 seconds of delay per channel, and noise and sine-wave generators. Also includes line voltage monitoring when installed in Crown CTs series amplifiers. Requires FREE IQwic Software and a computer for initial setup.


  • 100Mb Ethernet single-plug solution for TCP/IQ control and monitoring
  • Listen Bus amplifier output monitor
  • 24 bit conversion with 32 bit, floating point DSP processing
  • 64 assignable filters with 9 different filter types including all-pass filters
  • Over 2 seconds of delay available per channel
  • Input compressors and output limiters for each channel
  • Dual, uncorrelated noise generators for noise masking
  • Sine-wave generator
  • Load supervision
  • Full error reporting
  • Firmware upgrades via the network
  • 10 user selectable presets
  • Reliable FLASH memory backup of all parameters
  • Three Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications.

Internal Controls A Reset/Preset switch, accessible with a straightended paper clip through the PIP panel, selects the next user preset if pressed for less than 2 seconds, resets the PIP to preset "0" if pressed for more than 2 seconds.
Balanced Audio Input Connectors 3-pin removable barrier-strip connector for both channels
AUX Connector Configurable for AUX input, AUX output or Listen Bus
Network Connector The network connector is a standard RJ-45 connector that allows the IQ-PIP-USP3 to connect to an Ethernet network. Connectrion is made using a standard CAT 5 cable to a network switch port. In cases where an IQ-PIP-USP3 is used in stand-alone mode (not co
Preset Indicator Signals the number of the current preset, if active, by flashing a series of flashes equal to the current preset number.
IQ Data Indicator Flashes when the IQ-PIP-USP3 receives a valid command that is addressed to the IQ-PIP-USP3.
Reset/Preset Switch Used to change presets, restore settings to factory default or restore all the presets to the factory defaults. During operations of the switch, the Data indicator flashes as an aid to the user.
