DESCRIPTION
TheP4000trans•novaDIAMOND(patentpending)amplifierisperfectformany
studio monitoring, touring sound and fixed installations. It features Jim
Strickland’s trans•nova circuitry (patent #4467288) and
his brilliant discovery, Dynamically Invariant
AMplification Optimized Nodal Drive. The DIAMOND
transconductancedriverstagecombinesthelinear-
ity of Class A operation with the current headroom
of a Class B system resulting in a significant ad-
vancementintheartofpoweramplifierdesign.Thesonic
result of all this unique technology is very easily heard. The P4000 presents
a deep, wide sound stage with incredible musical transparency and detail.
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 12 lateral
power MOSFET output devices. It shall be constructed on a 16 gauge steel
chassisutilizingconvectioncoolingandbetechnicianfriendlyusingmodular
construction.
Eachchannelshallberatedforaminimumof200wattsintoan8ohmloadand

beprovided for stereoor bridged monooperation 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
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.
Theamplifier’sfrontpanelshallprovidefullrangelevelcontrolswithoptional
