Adastra A4 4 x 200W Stereo Amplifier with FM Radio/Bluetooth & Media Player

The Adastra A4 is a fully featured dual stereo PA amplifier designed for commercial installations such as bars, restaurants, and function rooms, delivering 4 x 200W across two independent stereo output zones.

Each output zone has its own source selector, bass, and treble controls, letting you tailor the audio independently for different areas of a venue. Microphone inputs 1 and 2 are live to both zones at all times, making announcements and background music easy to manage simultaneously.

The built-in media player supports USB and SD card playback of MP3 audio tracks, and a Bluetooth receiver is included for wireless streaming. A front-panel 3.5mm auxiliary input offers a quick connection for additional sources alongside the two rear stereo line inputs.

• Dual Zone Output: Two independent stereo zones, each with individual source selection, bass, and treble controls for flexible venue audio management.
• High Output Power: Delivers 4 x 100W at 8 Ohms or 4 x 200W at 4 Ohms, with speaker connections via 4mm binding posts on the rear panel.
• Built-in Media Player: Plays MP3 files directly from USB drive or SD card, removing the need for a separate source device.
• Bluetooth Receiver: Wireless audio streaming from smartphones or tablets straight to the amplifier.
• Dual Microphone Inputs: Two 6.3mm jack mic inputs with talkover functionality, both active across all zones simultaneously.
• Class D Amplification: Efficient Class D design with built-in thermal, over-current, over-voltage, and short-circuit protection for reliable long-term use.
