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
security covers. The front shall also incorporate a lighted main power switch

arises.
Theamplifier shall fitstandard 19” EIArackmounting requirementsutilizing3-
rack spaces. The dimensions shall be 19” Wide, 11” Deep, 51⁄4” High, and be
finished in black with a net weight of 34 pounds. It shall be a Hafler P4000.
