Bosch PLE-2MA240 Plena Mixer Amplifier

The Bosch F.01U.066.937 is a Plena mixer amplifier that delivers 240 watts of power while handling both background music and public address across two separate zones. It combines the essential tools an installer needs with controls that any staff member can understand, so venues get professional sound without a steep learning curve.

Retail stores can run soft music throughout the day, restaurants can greet diners with a clear host mic, and offices or community centers can page staff or trigger an evacuation message when safety demands it. Six microphone or line inputs, each with its own gain control, let you plug in handheld mics, paging stations, or a wireless receiver. Three dedicated music inputs sit on a selector knob, making it easy to switch from a streaming player to a radio tuner or a media server.

The front panel keeps daily operation simple. A built-in two-tone chime signals that an announcement is coming, and the voice-activated priority circuit automatically lowers the music so speech comes through cleanly. Separate tone controls for microphone channels and music sources let you brighten vocal clarity without altering the warmth of a background playlist.

For system integrators, the rear panel offers 70 volt, 25 volt, and low-impedance 4-ohm outputs, along with line, music-only, and insert connections for external processing or recording. A 24-volt DC backup input with an integrated charger keeps the system alive during a power cut, which is essential for emergency paging and building code compliance.

The chassis measures about seventeen inches wide, four inches high, and just over ten inches deep, so it slides into a standard rack or sits on a shelf behind a counter. At roughly twenty-eight pounds, one person can lift it into place during installation. Once levels are set, everyday users simply adjust the master volume or choose the right zone, making the Bosch Plena amplifier a reliable centerpiece for small and medium-size sound systems.

Whether you need calm background music during store hours, routine paging in an office, or a fully compliant emergency override, this mixer amplifier provides a straightforward solution that you can trust day after day.
