QSC SPA4-100 Energy Star 4-Channel Powerhouse Amplifier
Unleash exceptional audio power with the SPA4-100! • It delivers 100 watts rms per channel into 4 or 8 ohms, and can bridge pairs for up to 200 watts rms. • The bridged pair channels can switch to 70V or 100V direct drive mode, giving up to 350 watts rms. • It's Energy Star qualified, saving energy and cost. This amplifier is perfect for sound system setups in venues like clubs, restaurants, and small theaters. Ideal for audio engineers and installers. Compact at 1.7 x 8.7 x 9.5 inches (43 x 220 x 241 mm) and weighing just 4.0 lb (1.4 kg), it's easy to install and transport.
Features:
- 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 ¨® Bridgeable outputs for higher power - Bridging the outputs of the SPA4-100 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.
