These Plena Economy mixer amplifiers are professional public address units with modern state‑of‑the‑art features. They 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. Offering the essentials of public address in an affordable package. Functions Microphone and line inputs 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 channel 1 can take priority over all other microphone and music inputs: u 4 microphone / line inputs, plus music source input u Announcement only output, 3‑wire volume override u Wide range of output power (60, 120 and 240 Watts) u 2‑tone chime • 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. Music input A separate music input is available with its volume control. Personalized settings More unique features are available such as a detachable label where the user can write the names for inputs. This label can then be mounted on the front, protected by the clear window. Another useful feature is to indicate preferred settings on the front panel by inserting colored pins at the preset levels of all knobs. You can then instruct a user to set all the controls to the silver pins to configure the system for their particular use. A second user can set all controls to the red pins for their configuration. Power The mixer amplifiers come in 60, 120 and 240 Watt output power. This power is directly available on 100 V (70 V for US versions) constant voltage connections and on a low impedance connection for a 4 ohm load. Moreover, the amplifiers have a separate 100 V (70 V for US versions) 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.Output status An LED VU meter monitors the master output. A headphone socket, below the VU meter, provides the mixer output. 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.
