The Adastra A8 is a four-zone stereo PA amplifier delivering 8 x 200W across four independent stereo outputs, built for professional installations that need high-quality stereo sound distributed across multiple rooms or listening areas.

Every output zone has its own dedicated rotary source selector and individual channel level controls, giving you precise, independent control over what each area of a venue hears. Both microphone inputs are simultaneously live to all four zones at all times, ensuring venue-wide PA coverage without any additional configuration.

Sources are connected to the rear panel alongside Euroblock speaker terminals for each zone, keeping installations tidy and secure. An IR remote control for the built-in media player is supplied in the box.

• Four Independent Stereo Zones: Each zone has its own source selector and level controls for Ch1–Ch8, allowing completely different audio to be sent to each area simultaneously.
• 8 x 200W Output: Delivers 8 x 100W at 8 Ohms or 8 x 200W at 4 Ohms via four rear-panel 4-terminal Euroblock connections.
• Built-in Media Player: Plays MP3 files from USB drive or SD card, with an IR remote control included for convenient source management.
• FM Radio Tuner: Integrated FM tuner with F-type external aerial connection for reliable broadcast reception in commercial settings.
• Bluetooth Receiver: Wireless audio streaming from any Bluetooth-enabled device directly into the amplifier.
• Dual Microphone Inputs: Two 6.3mm mono jack mic inputs with talkover, active across all zones simultaneously for seamless PA announcements throughout the venue.
