40W 4 Input 100V Public Address (PA) Amplifier

Designed to meet the requirements of medium sized professional public address installations. The A 4036A delivers an output power of 40W. Frequency response extends from 60Hz to 15kHz at a total harmonic distortion (THD) of less than 0.5%. Features include, VOX muting, four balanced XLR microphone inputs, four line RCA inputs, bass and treble controls, enabling a diversity of installation applications, including schools, public halls, workshops and sporting complexes. Inbuilt VOX muting allows input 1 (mic or line) to mute inputs 2-4 and input 2 (mic or line) to mute inputs 3-4.
Powered from 240V ac mains or 24V dc permitting battery backup operation during mains power failure. Output is 100V line or low impedance (4 - 16Ω) speaker loads. All units feature thermal overload shutdown to protect the amplifier if a speaker fault condition develops. Master volume can be controlled remotely via figure 8 cable and the A 2280B wall control unit or 1K potentiometer (part no. R 2202).

A 4573 Alert/evac option board:
Generates pre chime, bell, alert and evacuation tones. The alert tone can function continuously, or switch to evac tone after a preset time delay (adjustable 30 seconds to 4.5 minutes). Simply connects to the amplifier internally via the cable provided.

A 2280B Remote volume wall plate:
Connects via figure 8 cable to the “remote volume” terminals of the amplifier. Enabling overall volume to be adjusted as required. Features a PCB jumper to reverse the volume control direction. Maximum cable length 100m.
