AUDAC PRE220 dvouzónový desetikanálový předzesilovač

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
