Overview

The Sound Barrier PCS2500 is a professional two-channel analog power amplifier designed for permanent installations, cinema systems, and touring sound. Its Class H circuitry delivers 1,050W per channel at 4Ω and supports stable operation down to 2Ω per channel.

The PCS2500 offers Stereo, Parallel, and Bridge modes for flexible system configuration. A rear-panel Compressor switch engages or bypasses the built-in compressor. When engaged, the compressor helps manage signal peaks; it operates only when Input Sensitivity is set to 1.0V.

Balanced inputs, selectable input sensitivity, and front-panel channel level controls support straightforward integration and operation. Internal heatsinks and a variable-speed fan provide cooling, while built-in protection circuits help safeguard the amplifier during demanding use.

Class H Dynamic Power

The PCS series' proven Class H analog architecture dynamically shifts between multiple power-supply rails, supplying additional voltage and current when the music demands it. This provides the headroom needed to reproduce sudden peaks with speed, impact, and control while improving efficiency and reducing unnecessary heat. The result is powerful low-frequency response, clear transients, and the full, natural sound that has made the PCS Series a trusted choice among audio professionals for more than two decades.
