OVERVIEW
The Inter-M PA-120 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 120 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 “all-
call”) 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.
