The Inter-M PA-240 are integrated mixer amplifiers. They are complete and economical multi-purpose desktop 

mixer-amplifiers providing a cost-effective solution to public address and similar applications. Three versions are 

available with outputs of 60 watts respectively into direct (4 ohms) or distributed (70V/100V line) speaker systems. 

Each have six inputs; five microphones or line level selectable balanced on XLR-F and/or euro block connector inputs 

with rear mounted level selector switch setting the input sensitivity from mic to line level. The sixth input is high impedance

unbalanced on summing RCA connectors. A telephone input terminal is provided for telephone paging. 

Base and treble tone control provide sound equalization. VOX priority override is available on mic 1-2 and telephone inputs. 

Additionally there is a preamp mix out (500mV, 600 ohm); main amp in (1V, 47k ohm); which allows linking of multiple

amplifiers together. A master volume control, loudspeaker zone selection (5 zone and “allcall”) on 70/100 volt outputs and

built-in chime and siren tones (manual operation) is also featured. 

The PA-Series amplifier is designed for reliable service in permanent installations, and comes complete with short-circuit and

thermal protection and is ideal for voice reproduction and BGM applications. The PA-Series is an ideal solution for medical 

offices, restaurants, schools, etc.
