This PLENA Economy mixer amplifier is a professional public address unit with modern state‑of‑the‑art features. It is easy to use, taking the complexity away from the user and putting it where it belongs, inside the equipment. Providing crisp and clear announcements and music is as easy as turning on a radio.Offering the essentials of public address in an affordable package.
The mixer amplifier is equipped with an inbuilt music source, which can provide hours of uninterrupted music either through Bluetooth streaming or USB pen drive. It is supplied with an IR remote control for controlling the music source. The unit features four
mic/line inputs, 1 BGM and operates in a single zone. To ensure optimum performance, there are no moving parts, such as hard drives that can fail or wear out. The unit has a limiter circuit and provides an audio insert feature to use as a pre/power amplifier. The VU meter gives an output level indication.
The mixer amplifier has an output power of 60 W. This power is directly available on 100 V constant voltage connections and on a low impedance connection for a 4-ohm load. Moreover, the amplifier has a separate 100 V 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.
All mic/line inputs can be switched between microphone level and line level sensitivity. The inputs are balanced, but can be used as unbalanced inputs. Phantom power can be switched-on to provide power to condenser microphones. Input channel 1 can take priority over all other
microphone, AUX & 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
