DESCRIPTION
The trans•nova P3000 from Hafler! A company rich with heritage and experi-
ence. Building only the finest audio power amplifiers for professionals and
audiophiles the world over since 1975. The P3000
trans•nova is perfect for many studio monitoring, tour-
ing sound and fixed installations. Featuring Professor
James Strickland’s radical trans•nova topology
(TRANSconductance NOdal Voltage Amplifier). This cir-
cuitry (patent #4467288) was first introduced in our 9500 and
promptly blew away expensive esoteric amps taking audio technology up to
a whole new level in performance.
New LED indicators allow visually monitoring the operating status of each
channel. The Thermal and Short indicators light when these protection cir-
cuits have been activated. The Clip indicator assists in protecting the speak-
ers by showing when the amp is overdriven and the output signal is distorted.
The Signal indicator lights to show the presence of an audio signal.

ARCHITECT’SAND ENGINEER’SSPECIFICATIONS
The audio power amplifier shall be solid state design employing 8 lateral
power MOSFET output devices. It shall be constructed on a 16 gauge steel
chassis utilizing convection cooling and be technician friendly using modular
construction.
Each channel shall be rated for a minimum of 150 watts into an 8 ohm load and
200 watts into a 4 ohm load with both channels driven. In bridged mono mode,
the amplifier shall produce at least 400 watts into an 8 ohm load. A switch shall
be provided for stereo or bridged mono operation and all power ratings shall
be measured from 20Hz-20kHz with less than 0.2% THD.
The amplifier’s back panel shall provide Balanced inputs via combination XLR
and 1/4” phone jacks. The back shall also utilize gold-plated 5-way binding
posts for output connectors and a switch to isolate or connect the signal
ground to the chassis ground. The amplifier shall include a 3-wire grounded
AC line cord and UI power transformer operating on 120V/60Hz AC mains. An
optional transformer for 230V 50-60Hz operation shall be available.
The amplifier’s front panel shall provide level controls with optional security
covers. The front shall also incorporate a lighted main power switch and
indicators for each amplifier channel. The indicators shall display signal
present when 30mV of signal is detected, signal clipping when distortion rises
above 1%, thermal protection should the heatsink temperature become exces-
sive, and short circuit protection in case a problem on the speaker system
arises.
The amplifier shall fit standard 19” EIA rack mounting requirements utilizing 2-
rack spaces. The dimensions shall be 19” Wide, 97⁄8” Deep, 31⁄2” High, and be
finished in black with a net weight of 23 pounds. It shall be a Hafler P3000.
