Compact and high power 100V mixer-amplifiers with built-in media player. A combination jack/XLR microphone input has switchable phantom power and optional Vox priority function. Music playback is served by the internal media player, which has selectable source for USB mp3 playback, DAB+ or FM radio tuner, Bluetooth®, or a front mounted 3.5mm Aux input. An Aux line input has an independent volume control on the front panel. The amplifier produces a high power output to either 100V line or low impedance speaker loads down to 2 ohms, switchable via a DIP switch and connected on screw terminals, with level governed by a Master volume control and EQ handled by mini Bass and Treble rotary controls. The rear panel also has connections for a DAB+ or FM antenna or aerial and 24V mute contacts for triggering from a fire panel or emergency evacuation system. Each amplifier is supplied with brackets for mounting 2 units side by side in a 1U 19" rack or fitted to flat-mount the amplifier against a wall or under a counter-top. With a minimal control footprint and easy-to-manage controls, these mixer-amplifiers represent a versatile platform to build a public address installation for medium-sized areas or paired with further amplifiers as part of a wider sound system.
