Details
The PLE-1MA120 Plena mixer amplifier is a high performance, professional public address units with modern state of the art features. It are easy to use, taking the complexity away from the user and putting it where it belongs, inside the equipment. Providing a crisp call or clear music is as easy as turning on the radio.
All mic/line inputs can be switched between microphone level and line level sensitivity. The inputs are balanced but can be used unbalanced. Phantom power can be switched on to provide power to condenser microphones. Input channels 1 and 2 can take priority over all other microphone and music inputs. Input 1 can be activated by contact closure on the PTT (push to talk). A 2-tone chime can be configured to precede an announcement. Input 2 can be switched automatically if a signal is fed to the input, i.e., if someone speaks into the microphone (VOX activation). When one or both inputs are configured to have priority, the amount of attenuation of the RCA input, can be set between ‑2 dB (little attenuation) or -∞ dB (mute). This provides a talk-over or voice-over function. Input channels 1 and 2 also feature selectable speech filters to enhance the clarity of announcements.
The mixer amplifier comes in 120W output power option. This power is directly available on 25 / 70V constant voltage connections and on a low impedance connection for a 4 ohm load. Moreover, the amplifier has a separate 70V call-only output channel for addressing areas where only priority announcements are required. The call-only output can also be used for 3-wire remote, volume control override.An LED VU meter displays the master output level. A headphone jack socket, below the VU meter, provides the mixer output signal. For total reliability and ease of use, a limiter is integrated into the output stage to restrict output if the user applies too much signal.
