Basic Mixer Amp – PA-240


SKU: PA-240 Category:


240W Public Address mixer amplifier, 4å_/8å_/70V/100V. 2RU, SMPS, 6 audio inputs, Tel. input, priority volume control. Phantom power and speaker zone preset. 5 zone selector, Chime and Siren and dB meter on front panel.

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 equalisation. 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 ÒallcallÓ) 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.


Frequency Response (CH1~6)
The new PA-240 offers enhanced frequency response compared to the former PA-2000. With an improved widened frequency response of 50Hz to 16Kz the new PA series offers better speech intelligibly and higher quality sound for Music reproduction.

S/N Ratio
The new PA series has a higher signal to noise ration than its predecessor does. With a 78db S/N the new PA series delivers better desirable power ratio than noise giving it great tone and high-resolution sound.

Power Consumption (1/8W Output)
Among their advantages is their power efficiency, reduced power consumption and lower heat dissipation over traditional amplifiers.
