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.

WARRANTY

• 5 Year Warranty

ARCHITECT’S AND ENGINEER’S SPECIFICATIONS

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 exces­sive, and short circuit protection in case a problem on the speaker system
arises.
