The QSC SPA2-60 is a compact, ENERGY STAR®-qualified 2-channel power amplifier, delivering 60 watts per channel into 4 or 8 ohms, and up to 250 watts in bridged 70V or 100V mode. Its efficient Class-D design and convection cooling ensure quiet operation and reduced energy consumption. The Auto-Ramp feature provides silent power-up and power-down transitions, making it ideal for installations in meeting rooms, classrooms, and background music systems. Housed in a 1U, half-rack enclosure, the SPA2-60 offers flexible mounting options, including rack, table, and wall installations. With a frequency response of 20 Hz to 20 kHz and a signal-to-noise ratio greater than 100 dB, it ensures high-quality audio performance. The amplifier also includes protection features such as RMS and thermal limiting, as well as safeguards against overcurrent, short circuit, and voltage irregularities.
• Up to 60 watts per channel into 4 and 8 ohms — The outputs of the SPA2-60 and SPA4-60 are designed to provide 60 watts per channel into Low-Z loads
• ENERGY STAR® qualified amplifier — The SPA2-60 and SPA4-60 are EnergyStar qualified amplifiers; efficient class-D amplifiers that conserve energy and require no active cooling, so they reduce operational costs.
• Bridgeable outputs for higher power — Bridging the outputs of the SPA2-60 and SPA4-60 provide up to 200 watts into low impedance, and up to 250 watts into 70V or 100V providing outstanding flexibility.
• Auto-Ramp provides quiet startup and power-down — The EnergyStar Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 28 minutes of inactivity, dramatically reducing power consumption.
• Rack-mountable 1U, half rack width enclosure — The SPA2-60 and SPA4-60 can be mounted in 1/2 RU reducing rack space requirements. In addition their clever joining brackets enable easy under-table and wall-mounting.
