  • Stereo, Mono Parallel, And Bridge Modes Adapt To Diverse Speaker Configurations
  • Balanced XLR Loop-Through Outputs Enable Clean System Daisy-Chaining
  • Three Speakon Speaker Outputs Cover Both Channels And Bridge Without Adapters
  • Switchable Low-Cut Filter Protects Loudspeakers From Damaging Low-Frequency Content
  • Selectable Input Sensitivity Matches A Wide Range Of Source Signal Levels
  • Ground Lift Switch Eliminates Hum Caused By Ground Loops In Installed Systems
  • Comprehensive Fault Protection Guards Against DC, Thermal, Overload, And Short-Circuit Conditions

The Astatic 2-Channel Class D Power Amplifier series targets system designers and integrators who need reliable, space-efficient amplification for commercial installed audio, houses of worship, education facilities, and corporate AV environments. Both models occupy a single 1U rack slot in a 19-inch chassis, making them practical choices for tight equipment racks where thermal management and long-term reliability are non-negotiable. A switch-mode power supply with soft-start circuitry keeps inrush current low and supports demanding continuous-duty cycles without sacrificing output stability.

The series is available in two output tiers, allowing designers to right-size amplification for the application at hand, from distributed background music systems to high-output speech reinforcement and music reproduction. Stereo, mono parallel, and bridge operation modes give integrators the flexibility to drive a wide range of loudspeaker configurations from a single chassis. Balanced XLR loop-through outputs simplify daisy-chaining across multi-amplifier systems, and three Speakon speaker outputs cover channel A, channel B, and bridge configurations without adapters.

Where this series stands apart from conventional rack amplifiers in the same price class is in the depth of its protection and control features. Integrated peak limiting, a switchable low-cut filter, selectable input sensitivity, ground lift, and a full suite of fault protection circuits covering DC, thermal, overload, and short-circuit conditions make these amplifiers appropriate for permanently installed and mission-critical deployments where service calls are costly and unacceptable.
