Omnitronic MP-60 PA Mixing Amplifier

The Omnitronic MP-60 PA mixing amplifier is a compact, fan-cooled unit designed for public-address and background-music systems. It provides outputs for 70 V or 100 V PA speaker lines and can also drive low-impedance speakers (4–16 Ω). The amplifier offers three microphone inputs and three stereo line inputs, plus a stereo line output and a switchable chime. Frequency range is 80–14,000 Hz and the unit includes a 7-segment LED level display.

Advantages

The MP-60 PA features separate level controls for each of the three microphone inputs and three line inputs, plus master, treble and bass controls for flexible tonal adjustment. Microphone input 3 includes an adjustable priority circuit for paging or emergency announcements. Protection circuits with LED indication cover over-current, short circuit and turn-on delay. Its fan cooling ensures stable operation in continuous-use environments, and the compact 483 x 400 x 88 mm housing fits standard rack installations.

How to use

Connect speakers to the appropriate 70 V/100 V PA terminals or to the low-impedance outputs for 4–16 Ω speakers according to your system design. Plug microphones into the 6.3 mm jacks and set individual channel levels; use the adjustable priority on microphone input 3 if paging must override music. Connect source devices to the stereo RCA line inputs and route a feed from the stereo RCA line output if required. Adjust treble, bass and master controls to achieve the desired overall sound and monitor the 7-fold LED display for output levels. Ensure the unit has adequate ventilation for the fan-cooled design.

Recommendations

For reliable long-term operation, install the amplifier in a ventilated rack space, avoid covering ventilation openings, and match speaker impedance and PA line voltage (70 V or 100 V) to the output selection. Use the priority input only for essential paging to prevent frequent interruptions of background audio.
