Adastra 7-Channel Mic/Line Rack Mixer, 1U 19 Inch

The Adastra 7-Channel Mic/Line Rack Mixer is a versatile 19-inch 1U rack-mountable audio mixer, designed for professional installed sound systems. It offers comprehensive input options with four balanced microphone inputs and three stereo auxiliary line inputs, providing great flexibility for various audio sources.

A key feature is the priority microphone input on channel 1, which is equipped with +20V phantom power and includes an adjustable voice-over muting function for the auxiliary channels. This allows for clear priority announcements, such as emergency paging. The mixer can also be connected to an external 100V line PA system via its priority input terminals, enabling seamless integration into existing public address setups.

Professional Control and Output

Output is handled via stereo 6.35mm (1/4”) jack connectors, with dedicated master bass and treble tone controls on the front panel for precise sound shaping. Additional rear panel controls allow fine-tuning of the auxiliary muting level and priority input level, giving you complete command over your audio mix.

Dual Power Options and Build

The mixer supports flexible power options, accepting a standard 100-240V AC supply via an IEC connector or a 24V DC input via terminal blocks, making it suitable for both permanent installations and mobile setups. Its robust 1U rack-mount design ensures it fits neatly into standard audio racks, saving valuable space.

With a wide frequency response tailored for each input type and high-quality components, the Adastra mixer delivers clean, reliable audio performance. It is an ideal solution as either a master mixer for a small system or as an extension mixer in a larger, multi-zone installation.
