The PLE-4MA240-CN is a high performance 4-zone mixer amplifier, built on energy efficient class-D technology. Three selectable music sources, including a front panel 3.5mm input for hand-held device connection, provide flexibility for background music source. Multiple levels of priorities and ducking of music make this amplifier an excellent choice for background music and business paging.
Microphone and line inputs One microphone input (Input 1) can be switched between microphone level and line level sensitivity. The other two microphone inputs can be connected with XLR or TRS type connectors. Phantom power can be switched on to provide power to condenser microphones. Input 1 can take priority over all other microphone and music inputs: Input 1 priority can be activated by contact closure on the PTT (push to talk). A 2-tone chime can be configured to precede an announcement. Music inputs Separate music inputs are available with their own input selector and volume control. The user can choose a music source like a CD/DVD player or radio (like the PLE-SDT), and set the level of music. A front panel music input makes it easier to connect a handheld device as music source. Personalized settings More unique features are available such as detachable labels where the user can write the names for inputs, music sources and output zones. These labels 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. Integration A telephone / 100V emergency input is provided for easy integration with a telephone paging system or another Public Address system. It has its own preset volume control and overrides all other inputs, including input 1.
