ADASTRA 1U Zone Mixer with 4 Stereo Outputs

The ADASTRA 1U Zone Mixer is a professional live and zoning rack mixer engineered for flexible audio routing in a compact 1U format. It features two balanced microphone/line inputs and two selectable stereo line inputs, feeding four independent stereo outputs. This design allows microphone channels to be broadcast to all zones simultaneously, while the stereo channels can be individually switched to any required output, enabling precise control over multi-room or multi-zone audio distribution.

The mixer is equipped with comprehensive controls for professional sound shaping. Each microphone channel includes a low-cut rumble filter, a 3-band EQ, and switchable 48V phantom power for condenser microphones. The stereo line channels feature a 2-band EQ and A/B source selection. A foot-switchable DSP reverb or external effects loop adds depth and ambience to vocals or instruments, enhancing live performances.

Ideal for a variety of applications, from adding a vocal mix to a DJ setup to creating a sophisticated multi-zone audio system in venues such as bars, restaurants, houses of worship, or retail spaces. The inclusion of emergency mute contacts allows for integration with fire alarm systems, automatically muting all audio except microphone channel 1 for critical announcements.

Connection and Integration

Connection options are extensive and practical. Mic/line inputs use combination XLR/jack sockets, while stereo inputs offer a choice between 6.35mm jack and RCA. Outputs 1-3 are on RCA connectors, with Output 4 on a 6.35mm jack, providing compatibility with a wide range of professional and consumer equipment. A dedicated 6.35mm jack for external effects and modular terminals for fire alarm contacts complete the connectivity suite.

Housed in a robust rack-mountable chassis, it is powered by a universal 230–250VAC 50Hz supply and includes a UK Type G mains plug. With its blend of routing flexibility, robust
