QSC SPA2-60 Two Channel Energy Star Commercial Amplifier

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.

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

The SPA Series amplifiers from QSC are four half rack 1U, convection cooled power amplifiers delivering two or four channels of up to 200 watts per channel into 4 ohm and 8 ohm. These amplifiers can also be bridged to supply up to 400 watts into 4 ohm and 8 ohm, and up to 350 watts into 70V or 100V loads making them extremely flexible for Low-Z or High-Z applications. Utilizing an advanced Class-D amplifier design and Universal Power Supply the SPA Series are amazingly efficient allowing them to be convection cooled and are ENERGY STAR qualified with quiet auto-ramp standby functionality. The SPA Series amplifiers are housed in an unobtrusive black painted 1/2 RU chassis with unique mounting hardware enabling rack, table and wall mounting capabilities.
