This PA amplifier has been designed to meet the requirements of small to medium sized professional public address installations. Frequency response extends from 40Hz to 10kHz at a total harmonic distortion (THD) of less than 0.5%. Features such as push to talk (PTT) auxiliary muting, three combined balanced line microphone / stereo line inputs, tape out, and separate bass and treble controls give this amplifier a wide scope of installation applications, including schools, public halls, workshops and sporting complexes. Output may be 100V line or low impedance (8 - 16Ω) speaker loads. This unit features thermal overload shutdown, over current and short circuit protection.Vox muting: The VOX circuit allows telephone paging via line input one or two (selectable internally). When paging via the telephone, all other line inputs are muted (ie. background music). Features variable sensitivity and time delay settings.

NOW EQUIPPED WITH 4 XLR MIC & 4 RCA LINE INPUTS
Designed to meet the requirements of medium sized professional public address installations, delivering an output power
of 40W, 60W and 100W RMS respectively.Frequency response extends from 60Hz to 15kHz at a total harmonic distortion (THD) of less than 0.5%. Features include, VOX muting, four balanced line microphone inputs, four stereo line input sockets, and separate bass and treble controls enabling a diversity of installation applications, including schools, public halls, workshops and sporting complexes.VOX muting is in-built and can be activated on inputs 1 & 2 as required via the internal jumpers. Once activated input 1 will override all other inputs, including the alert/evac input. Input 2 will override inputs 3 & 4.
Powered from 240VAC mains or 24VDC permitting battery backup operation during mains power failure. Output is 100V/70V line or low impedance (4 - 16 Ohm) speaker loads. Note: 70V line is unavailable on the A 4036 40W amplifier.
All units feature thermal overload shutdown to protect the amplifier if a speaker fault condition develops.Master volume can be controlled remotely via a figure 8 cable and a A 2280A wall control unit or 1K potentiometer (part no. R 2202).
Features:
Desk or 19" rack mountable
Low noise and distortion levels
4 balanced microphone inputs
4 stereo to mono auxiliary inputs
Internally selectable phantom power
Optional tone generator board (A 2073)
Selectable VOX muting on inputs 1 & 2
