The QMA400v2 media amplifier combines a MP3 player, a FM Tuner and a multitude of microphones and stereo sources with a high-headroom stereo power amplifier in one compact unit. Add a VCA volume remote control option for its main output, the QMA400v2 extends the its applications into venues with more complex requirements. With the additional zone output, the unit can be configured to either use the internal amplifier as a stereo amplifier and an external amplifier for the zone signal, or to use the internal amplifier as a dual mono unit, one for the main and one for the zone signal. A music on-hold output allows to feed the unit’s music program into a telephone system. Adding the seamless integration with fire evacuation systems, the QMA400v2 is the default choice of any mid-scale venue operator.
