A 4031C 30W 100V Public Address Amplifier
Overview
This PA amplifier has been designed to meet the requirements of
small to medium sized professional public address installations.
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. This unit features thermal
overload shutdown, over current and short circuit protection.
High Performance
Frequency response extends from 40Hz to 10kHz at a total
harmonic distortion (THD) of less than 0.5%. Output may be 100V
line or low impedance (8 - 16Ω) speaker loads.
VOX Muting Functionality
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.
