AUDAC PRE220 pré-amplificador de duas zonas e dez canais

The AUDAC PRE220 is a professional two-zone preamplifier that delivers ten channels of flexible audio routing with exceptional clarity and low noise. Its dual-zone architecture allows independent source selection and volume control for two separate areas, making it an ideal backbone for restaurants, retail spaces, and corporate environments. The unit features two balanced microphone inputs with switchable phantom power, eight unbalanced line inputs, and balanced XLR zone outputs for robust signal integrity over long cable runs. A dedicated priority function on microphone input one and the paging input ensures important announcements automatically override background music. Front-panel bass and treble controls per zone, along with RS232 connectivity for integration with control systems, provide complete command over your audio distribution. Housed in a compact 1U 19-inch rack-mountable chassis, the PRE220 combines versatility and reliability in a single, professional-grade solution.

Advantages

Dual-zone operation allows independent source and volume control for two areas, eliminating the need for multiple preamps. Balanced outputs minimize noise and interference, ensuring pristine audio even in electrically noisy environments. The priority function automatically ducks background music for paging or emergency announcements, enhancing safety and communication. Switchable phantom power supports condenser microphones without external supplies. RS232 and optional wall panels enable remote control, simplifying daily operation for staff. The 1U rack-mount design saves valuable equipment space while maintaining professional standards.
