Adastra V Series Dual Zone 100V Mixer Amplifiers with DAB, Bluetooth & USB

The Adastra V Series is a dual-zone 100V mixer-amplifier with a Class-D amplifier section, designed to deliver independent audio to two separate areas from a single rack-mount unit.

Available in 2 × 120W and 2 × 240W output variants, it is built for commercial and leisure installations where different spaces need different audio — such as a bar and a dining room, a retail floor and a stockroom, or a hotel lobby and a function suite. Each zone is independently controlled and can carry a different source, making it a genuinely versatile solution for multi-area sound.

Built-in audio sources include a DAB+/FM tuner, Bluetooth 5.0 receiver, and a USB/SD media player, all accessible without any external playback equipment. A rotary source selector per zone switches between two unbalanced line inputs, an auxiliary input, or the internal media player, giving each zone its own independent programme selection.

Three balanced mic/line input channels are live to both zones simultaneously, with switchable +20V phantom power on the XLR inputs and selectable priority for channel 1. Front-panel jack inputs and rear-panel combo XLR/jack and screw terminals give flexible connection options for both temporary and permanently wired microphone sources. Each zone also has its own bass and treble EQ, plus an unbalanced line output for connecting additional slave amplifiers to expand the system further.

• Two Independent Zones: Each zone has its own volume, EQ, and source selection, allowing completely different audio programmes to be played simultaneously in two separate areas.
• DAB+/FM, Bluetooth & USB/SD: Three built-in playback sources cover digital radio, wireless streaming, and stored media without any additional equipment.
• Flexible Mic/Line Inputs: Three balanced mic/line channels with switchable phantom power accept both condenser and dynamic microphones via front jack, rear combo XLR/jack, or screw terminals.
• Per-Zone EQ: Independent bass and treble equalisation for each zone allows the sound to be tailored to suit different room acoustics or listener preferences.
• Zone Line Outputs: Each zone has a dedicated RCA line output for connecting RS Series slave amplifiers or other powered speakers to extend coverage.
• 100V or Low-Impedance Output: Each zone supports 100V line, 8 Ohm, or 4 Ohm speaker loads, providing compatibility with a wide range of speaker types.
• 19" Rack Mountable: Supplied with rack-mounting ears as standard for clean integration into a standard equipment rack.
