The SPA4-100 is a compact, energy-efficient installation amplifier designed to deliver reliable performance in commercial and professional audio environments. Featuring a space-saving 1U half-rack design, high-efficiency Class-D operation, bridgeable outputs for increased power, and intelligent Auto-Ramp technology for silent startup and shutdown, it provides flexible amplification while minimizing energy consumption and operating costs.
- Up to 200 watts per channel into 4 and 8 ohms — the outputs of the SPA4-100 model are designed to provide up to 100 watts per channel into Low-Z loads.
- ENERGY STAR® qualified amplifier - The ENERGY STAR qualified SPA amplifiers employ an efficient class-D design to conserve energy and reduce operational cost.
- Bridgeable outputs for higher power — Bridging the outputs of the SPA4-100 will deliver up to 175 watts per channel pair into 70V or 100V when bridged.
- Auto-Ramp provides quiet startup and power-down — The ENERGY STAR auto-ramp circuitry ensures quiet and fast power up from standby and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.
- Rack-mountable 1U, half rack width enclosure — The SPA amplifers can be mounted in 1 RU, 1/2 rack space, and their clever joining brackets enable easy under-table and wall-mounting
