Introduction
The Vorsis HD P3 Digital Multiband Signal Processor unit occupies one 19”
wide rack space (height 1 3/4”), and is 17.346” deep. The two-channel/stereo audio
processorprovidesanarrayofanalog/digitalinputsandoutputs,four-bandparamet-
ricEQ,three-bandcompressor,andtunablefilters,alongwithoverallAGC,limiting,
and expansion. All settings can be stored and replayed as password-protected
presets. The front panel display includes input, output, and gain reduction meters.

TheXLR,DB-25,DB-9andCAT5connectorslocatedontherearofchassisgive
you maximum installation versatility.
Energizing
Assuming the Vorsis HD P3 Digital Multiband Signal Processor is correctly
rackmounted, you may now energize it by connecting the factory supplied power
cord to the rackmount unit and then plugging it into the AC mains.
Note:Tode-energizetheVorsis HD P3,unplug its ACcord from theAC mains.

I/O Connections
All audio input and output, control, Ethernet, and power supply
connections are made via various connectors mounted on HD P3’s rear
panel. Seven XLR connectors are provided for analog and digital audio
input and output, and all the audio connections also appear on the DB-25
connector.AnRJ-45connectorisprovidedforEthernet connections. The
DB-9 connector provides 8 GPI inputs for the most used presets. The
pinout drawings on pages 1-8 and 1-9 summarize all wiring connections.
Inputs
BothHDP3processorsignalpathscanbefedfromtwodifferenttypes
of inputs: analog line level and AES-3 digital.
Two female XLR connectors, or the appropriate pins on the DB-25
AUDIO I/O connector, are available for line level analog audio input
(nominal +4dBu balanced) connections. The analog line inputs exhibit a
bridging impedance and can handle signals up to +20dBu.
A third female XLR connector is available to handle digital line level
sources;thisAES-3digitalinputisalsoavailableontheDB-25connector.
The HD P3 will accommodate digital inputs having sample rates of
44.1kHz or 48kHz. The internal sample rate of the HD P3 will automati-
cally sync up to the applied input signal’s valid sample rate, allowing the
HDP3tobeused in an existingdigitalsystem.AESsources are by design
stereo; if the HD P3 is not set to be stereo the appropriate Left or Right
signal within the AES stream will be applied to the signal path.

Outputs
The HD P3’s two output signals are available as individual line level analog (+4dBu,
balanced) on the two male XLR ANALOG OUT connectors, and in digital AES formatted
on the two male XLR AES OUT connectors. These analog and digital outputs are available
also on the DB-25 connector.
