Amplifier Introduction
Audix Systems 60 watt 'PowerBloc' amplifier modules are used individually or
combined to provide 100 Volt line outputs of 60, 120, 180 or 240 Watts R.M.S. A
rack mounting chassis/power supply occupying 3U of space holds up to four
PowerBloc modules which may be arranged as four totally independent 60 watt
amplifiers or in any of ten other output configurations (see paragraph 1.2
‘Amplifier model range’ for details).
Using proven MOSFET circuit techniques results in an efficient and extremely
reliable power amplifier. The amplifiers are protected from short circuit speaker
lines by current limiting on the output stage. The amplifiers are protected from
persistently being over-driven by a thermal cut-out which is triggered at 85
°
C
decreasing the amplifier input drive to reduce the output stage power dissipation.
Modules operating in parallel share a single input/driver stage. Input level
controls may be fitted to all combinations of PowerBlocs as appropriate.
The output power of existing units can be increased at any time by the addition of
more PowerBloc output modules (subject to available space in the mainframe).
