Adastra A8300 4-Zone (8 x 300W) Bluetooth Mixer Amplifier, 4Ω Class-D, USB/FM/Optical
The Adastra A8300 is a high-powered 4-zone mixer amplifier delivering 8 x 300W, with flexible speaker configurations and integrated media playback.
The Adastra A8300 is a powerful 4-zone Class-D mixer amplifier designed for commercial multi-room audio systems where both high output and speaker flexibility are essential.
Each of the four output zones provides two independent 300W channels at 4Ω, offering a total of eight speaker outputs. This unique setup allows you to run up to four 8-ohm speakers per zone (two per channel) or even eight 16-ohm speakers per zone (four per channel), making it an excellent solution for large distributed installations.
Designed for retail, hospitality, public buildings, and leisure venues, the A8300 gives complete control over your audio environment. Each zone can operate in stereo or summed mono, with selectable sources including three stereo RCA line inputs, an optical S/PDIF input, a built-in FM tuner, USB/microSD media player, or Bluetooth streaming. Individual zone EQ controls for bass and treble, plus channel volume, allow tailored sound for each area.
Two microphone inputs with override capability support announcements or paging, and the 24V emergency mute terminal allows integration with fire alarm systems. Front-panel control makes it easy to manage settings, while the compact 2U rackmount form ensures tidy and reliable installation.
Whether for clear background music, powerful foreground playback, or multi-source zoning, the Adastra A8300 offers the versatility and performance required in modern commercial audio.
