QSC SPA4-100 ENERGY STAR 4-Channel Power Amplifier (100W/Channel)
The SPA4-100 four channel amplifier delivers 100 watts rms per channel into 4 or 8 ohms; the four channels can also be bridged in pairs, each pair providing up to 200 watts rms into 4 or 8 ohms. The SPA4-100 bridged pair channels can be switched into 70V or 100V direct drive mode providing up to 350 watts rms into a 70V or 100V output; when in 70V or 100V mode the 80Hz highpass filter is automatically engaged.

QSC SPA4-100 ENERGY STAR 4-Channel Power Amplifier (100W/Channel)
  • 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
