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 - 16

Ω

) 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.
