A 4033C • 30W 3 Input 100V PA Amplifier (Rack Mount Version)

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.

Key Features:

• 3 Inputs suitable for either microphone or line level, or for use as microphone and line level coupled together.
• Bass and treble controls (on both microphone and auxiliary inputs).
• Full 30W RMS output (100V and 4 -16Ω outputs).
• Push to talk muting.
• Protection against over-voltage, over current, thermal run-away and short circuit load.
• Internationally accepted IEC mains socket (240V AC operation only).
• Stereo RCA sockets for all auxiliary inputs (configured to mono internally allowing standard stereo equipment to be directly connected).
• Fully balanced microphone inputs.
• Tape output, suitable for recording, or for connection to a second amplifier.
