Q-SYS QSC SPA2-200 2-Channel Power Amplifier (200W)

For higher power the SPA2-200 two channel amplifier delivers up to 200 watts rms per channel into 4 or 8 ohms; the two channels can also be bridged providing up to 400 watts rms into 4 or 8 ohms. When the channels are bridged they can be switched into 70V or 100V direct drive mode providing up to 350 watts rms into a mono 70V or 100V output. Like the other SPA models, an 80Hz highpass filter is engaged when in 70V or 100V mode.

Key Features

• 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
