Designed for retail, hospitality, public buildings and leisure venues where true three-zone audio flexibility and high output power are required, the A6300 provides the same sophisticated functionality and comprehensive control surface as the A4300 with the added capability of a third fully independent output zone.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMultiple Input Sources \u0026amp; Flexible Zone Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eEach of the three output zones can be independently assigned to any of the available input sources — two stereo RCA line inputs, a 3.5mm aux input, optical S\/PDIF digital input for AV system integration, USB\/MicroSD media player, FM tuner or Bluetooth receiver. Each zone features independent 2-band EQ with bass and treble controls alongside master volume, and can be configured to operate in stereo or summed to dual mono depending on the speaker layout requirements of each area.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eBuilt-In Media Player, Bluetooth \u0026amp; FM Tuner\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe onboard media player supports MP3 audio playback from USB flash drives and MicroSD cards, and a Bluetooth receiver enables wireless streaming from smartphones and tablets.
