Four Channel, 100watt Professional Amplifier

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

• Up to 200watts per channel into 4 and 8ohms the outputs of the SPA4-100 model are designed to provide up to 100watts 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 350watts 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 1RU, 1/2 rack space, and their clever joining brackets enable easy under-table and wall-mounting
