DESCRIPTION
The P7000 trans•nova DIAMOND (patent pending) amplifier is the most pow-
erful 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-
binesthelinearityofClassAoperationwiththe
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
thisuniquetechnologyisveryeasily 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
P7000idealforbi-ampingandavariety of sound reinforcementapplications.
Hafler’s new DIAMOND and trans•nova circuitry topology in the P7000 repre-
sents 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 de-
manding motion picture sound tracks. Amazingly, the P7000 is excitingly ap-
propriate as an amplifier for instruments like bass guitar and keyboards be-
cause 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’SAND ENGINEER’SSPECIFICATIONS
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.
Eachchannelshallberatedforaminimumof350wattsintoan8ohmloadand
500watts*intoa4ohmloadwithbothchannelsdriven.Inbridgedmonomode,
the amplifier shall produce at least 1000 watts* into an 8 ohm load. A switch
shallbe provided for stereo orbridged mono operation and allpower ratings
shall be measured from 20Hz-20kHz with less than 0.2% THD.
Theamplifier’sbackpanelshallprovideBalancedinputsviacombinationXLR
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
groundto the chassis ground. Each amplifier channel shallincorporate dual
2ndorderButterworthcrossovers.Theamplifiershallincludea3-wiregrounded
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
presentwhen 30mV ofsignalisdetected,signal clipping whendistortionrises
above1%,thermalprotectionshouldtheheatsinktemperaturebecomeexces-
sive, and short circuit protection in case a problem on the speaker system
arises.
Theamplifiershallfit standard 19” EIA rack mounting requirementsutilizing2-
rack spaces and have handles. The dimensions shall be 19” Wide, 127⁄8”
Deep**, 31⁄2” High, and be finished in black with a net weight of 40 pounds. It
shall be a Hafler P7000.
*Continuous power limited by current rating of line fuse. **plus 11/8” for handles
