DESCRIPTION
The P7000 trans•nova DIAMOND (patent pending) amplifier is the most powerful and versatile amplifier Hafler has ever made! It features Jim Strickland’ s
trans•nova circuitry (patent #4467288) and his brilliant discovery,
Dynamically Invariant AMplification Optimized Nodal Drive.
The DIAMOND transconductance driver stage com-
bines the linearity of Class A operation with the
current headroom of a Class B system result-
ing in a significant advancement in the art of
power amplifier design. The sonic result of all
this unique technology is very easily heard. The
P7000 presents a deep, wide sound stage with
incredible musical transparency and detail.
Hafler – One for All! Both powerful and flexible, the P7000 features active
crossovers controlled by our XCard plug-in modules (2 per side) making the
P7000 ideal for bi-amping and a variety of sound reinforcement applications.
Hafler’ s new DIAMOND and trans•nova cir cuitry topology in the P7000 repr esents a great sonic advancement over the successful PRO5000, confirming
once again Hafler’s dominance as “the amplifier of choice” to power large
studio reference monitor speakers. The P7000 is also an excellent choice for
cinemas wanting the best possible amplification to reproduce today’s demanding motion picture sound tracks. Amazingly, the P7000 is excitingly appropriate as an amplifier for instruments like bass guitar and keyboards because of its punch, control, and musicality.
Whether used for Sound Reinforcement or fixed installs, Hafler delivers an
experience that no other amplifier can match. Sonics for Audiophiles made
bulletproof for the road!

ARCHITECT’S AND ENGINEER’S SPECIFICATIONS
The audio power amplifier shall be solid state design employing 16 lateral
power MOSFET output devices. It shall be constructed on a 16 gauge steel
chassis utilizing forced air cooling and be technician friendly using modular
construction.
Each channel shall be rated for a minimum of 350 watts into an 8 ohm load and
500 watts* into a 4 ohm load with both channels driven. In bridged mono mode,
the amplifier shall produce at least 1000 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. Each amplifier channel shall incorporate dual
2nd order Butterworth crossovers. 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.
LUCASFILM
