The SPA Series are half rack 1U, convection cooled power amplifiers, delivering two or four channels of 60 watts per channel into 4Ω and 8Ω. These amps can also be bridged to supply 250W per channel pairs into 70V or 100V 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 ENERGY STAR® qualified with quiet auto-ramp standby functionality. The SPA2-60 and SPA4-60 are housed in an unobtrusive 1/2 RU chassis with unique mounting hardware enabling rack, table and wall mounting capabilities.
Efficient class-D amplifiers that conserve energy and require no active cooling, so they reduce operational costs.
Bridging the outputs of the SPA2-60 and SPA4-60 provide up to 200 watts into low impedance, and 250 watts into 70V or 100V providing outstanding flexibility.
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.
