The QSC SPA2-200 is a compact, ENERGY STAR®-qualified 2-channel power amplifier engineered for versatility and efficiency in both commercial and residential audio installations. Delivering up to 200 watts RMS per channel into 4 or 8 ohms, it supports bridging to provide 400 watts into 4 or 8 ohms, or 350 watts into 70V/100V systems, making it adaptable for various low- and high-impedance applications. Its Class-D topology ensures high efficiency and low heat generation, allowing for convection cooling without the need for fans. The amplifier features an Auto-Ramp function for silent power-up and power-down transitions, reducing energy consumption during periods of inactivity. Housed in a half-rack, 1U chassis, the SPA2-200 offers flexible mounting options, including rack, under-table, and wall installations, catering to space-constrained environments. With a frequency response of 20 Hz to 20 kHz, a signal-to-noise ratio exceeding 100 dB, and an 80 Hz high-pass filter engaged in 70V/100V mode, it ensures clear and reliable audio performance across various setups.
• Up to 200 watts per channel into 4 and 8 ohms — the outputs of the SPA2-200 model are designed to provide up to 200 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 SPA2-200 will deliver up to 350 watts 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
