A 4033B • 30W 3 Input 100V PA Amplifier (Rack Mount Version)
The rack mount version of our A 4031B 30W amplifier, possibly the most popular PA amplifier ever sold in Australia! This 30W model is the mainstay of the small & medium PA install range, offering both 100V line and low impedance outputs. Suits a wide scope of installation applications, including schools, public halls, workshops and sporting complexes.
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.
