Description

The Adastra A8 is a professional quad stereo amplifier designed for high-quality multi-zone installations, delivering 8 x 200W RMS at 4 Ohms. It provides 4 independent stereo zones, each with its own rotary source selector and level control, making it ideal for distributing music across multiple rooms or areas. The amplifier integrates a built-in media player that supports MP3 playback from USB and SD card, plus a B/T wireless receiver for streaming audio and an FM tuner with external aerial input. Two microphone inputs remain live across all zones, perfect for announcements or paging systems. Constructed with efficient Class D technology, the A8 ensures clear audio with low distortion and a wide frequency response from 20Hz–20kHz. The durable rack-mount design includes Euroblock speaker outputs and protective circuits against thermal, overload, and short-circuit conditions. Reliable and versatile, the A8 is a complete audio solution for venues, schools, hospitality, and commercial spaces.
