Two-zone ten-channel preamplifier Audac PRE220 — two-zone, 10-channel audio preamp

The Audac PRE220 is a two-zone, ten-channel preamplifier designed for multi-zone audio systems. It provides signal routing and individual level control for two independent zones, allowing distribution of up to ten channels to external amplifiers or powered speakers. The unit supports flexible source connectivity for background music, paging systems and line-level sources in commercial or residential installations that require separate zone management and simple front-end control.

Advantages

The PRE220 offers compact, rack-mountable design with centralized control over multiple outputs, simplifying wiring and system configuration. Its two-zone architecture enables independent volume and source routing per zone, while ten output channels provide the capacity to feed several amplifiers or speaker lines. The preamplifier's straightforward signal management reduces the need for multiple source devices at each zone and allows easy integration with existing audio infrastructures.

Suitable for

• Background music distribution in offices, retail spaces and hospitality venues
• Multi-room audio installations in homes and small commercial buildings
• Paging and announcement systems where different areas require separate control
• AV systems that need multiple line-level outputs for powering several amplifiers

Key specifications

• Two independent zone outputs with per-zone level control
• Ten line-level output channels for distribution to amplifiers or powered speakers
• Multiple line-level inputs for connecting music sources, mixers or paging processors
• Rack-mountable form factor suitable for equipment racks and AV cabinets
• Front-panel controls for basic source selection and level adjustment

How to use

Install the preamplifier into a standard equipment rack and connect source devices to the line-level inputs. Route the ten output channels to the inputs of power amplifiers or active speakers serving the two zones. Use the front-panel level controls to set appropriate volume for each zone, and configure source routing according to the installation requirements. Adjust levels at the connected amplifiers as needed to match speaker sensitivity and room acoustics.

Usage recommendations

For stable performance, use high-quality, shielded audio cables for all line-level connections and maintain consistent grounding across components. During setup, start with lower output levels and increase gradually while listening in each zone to avoid abrupt level changes. Integrate the PRE220 with compatible amplifiers and passive or active speaker systems that match the intended coverage and power requirements for each zone.
