DESCRIPTION

trans•anaisbothcleverandinnovative! TheTRANSconductanceActiveNodal
Amplifier topology operates the output stage with its full voltage gain, which
allows the input stage to operate from a low voltage
regulated supply. The signal is then
shifted up in level to the high voltage
sectionby the driver stagewhichforms
an active node at ultrasonic frequen-
cies. This results in very stable, highly linear op-
erationproducinganaturalandaccuratesoundstagewithexceptional
image focus!
NOMAD – Our proprietary NOMAD (NOn-Multiplying Advanced Decision) sys-
tem very accurately computes the allowable device current for the device
voltageand clamps thegatedrivewhen the actualcurrentexceeds this value.
This improved accuracy is achieved by eliminating the dependence upon
unreliable, analog (multiplier) circuits to model the device operation.
NOMAD prevents sonic degradation associated with other conventional
protection circuits – something Hafler would never allow.

ARCHITECT’SAND ENGINEER’SSPECIFICATIONS
The audio power amplifier shall be solid state design employing 8 vertical
power MOSFET output devices. It shall be constructed on a 16 gauge steel
chassisutilizingconvectioncoolingandbetechnicianfriendlyusingmodular
construction.
Eachchannelshallberatedfor aminimum of50wattsintoan8ohm loadand
55 watts into a 4 ohm load with both channels driven. In bridged mono mode,
theamplifier shall produceatleast 110 wattsintoan8 ohm load.Aswitch shall
beprovidedfor stereo or bridged mono operation and allpowerratings shall
be measured from 20Hz-20kHz with less than 0.2% THD.
Theamplifier’sbackpanelshallprovideaswitchtoselectUnbalancedinputs
via gold-plated RCA jacks or Balanced inputs via combination XLR and 1/4”
phone jacks. The back shall also utilize a screw type terminal barrier strip for
outputconnectorsandaswitch to isolate or connect the signal ground to the
chassis ground. The amplifier shall include a 3-wire grounded AC line cord
anda switch to operate theUI power transformer on either115V/60Hz or 230V/
50-60Hz AC mains.
Theamplifier’sfrontpanelshallprovideFullRangelevelcontrolswithoptional
security covers. The front shall also incorporate a lighted main power switch
andindicators foreachamplifier channel. Theindicatorsshall displaysignal
presentwhen 30mVofsignalis detected,signalclippingwhen distortionrises
above 1%, and thermal protection should the heatsink temperature become
excessive.
The amplifier shall fit standard 19” EIA rack mounting requirements utilizing 1-
rack space. The dimensions shall be 19” Wide, 83⁄8” Deep, 13⁄4” High, and be
finished in black with a net weight of 12 pounds. It shall be a Hafler P1000.
