Description
The SPA Series amplifiers fromQSCare two half rack 1U, convection cooled power amplifiers delivering two or four channels of 60 watts per channel into 4 and 8. These amps can also be bridged to supply 200 watts into 4 and 8, and up to 250 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 SPA2-60 andSPA4-60are housed in an unobtrusive black painted 1/2 RU chassis with unique mounting hardware enabling rack, table and wall mounting capabilities.
Features
- Up to 60 watts per channel into 4 and 8 ohms The outputs of the SPA4-60 are designed to provide 60 watts per channel into Low-Z loads
- ENERGY STAR qualified amplifier The SPA4-60 is an EnergyStar qualified amplifier; efficient class-D amplifier that conserve energy and require no active cooling, so it will reduce operational costs.
- Bridgeable outputs for higher power Bridging the outputs of the SPA4-60 provide up to 200 watts into low impedance, and up to 250 watts into 70V or 100V providing outstanding flexibility.
- Auto-Ramp provides quiet startup and power-down The EnergyStar Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 28 minutes of inactivity, dramatically reducing power consumption.
- Rack-mountable 1U, half rack width enclosure The SPA4-60 can be mounted in 1/2 RU reducing rack space requirements. In addition their clever joining brackets enable easy under-table and wall-mounting.
