The SPA Series amplifiers from QSC are two half rack 1U, convection cooled power amplifiers delivering two or four channels of 60W per channel into 4 Ω and 8 Ω. The two channels can be bridged to supply 200W into 4 Ω and 8 Ω – and up to 250W into direct drive 70 V or 100 V mode – making them flexible for Low-Z or High-Z applications. There is also a selectable 80 Hz highpass filter for bridged operation, ensuring that 70 V or 100 V loudspeaker transformers are not overdriven and saturated by too much low frequency content. Utilizing an advanced Class-D amplifier design and Universal Power Supply, the SPA Series are remarkably efficient and are ENERGY STAR® qualified with quiet auto-ramp standby functionality. The SPA4-60 is housed in an unobtrusive black painted 1/2 U chassis with clever joining brackets that enable easy under-table and wall-mounting. It’s ideal for stereo or mono applications of voice or music audio content, and offers a powerful yet affordable amplifier that meets the needs of boardrooms, conference rooms and other corporate spaces where multiple speakers are in use.IncludesPower cableQuick start guideConnector kitRack-mount earsMounting bracketsFeaturesUp to 60W per channel into 4 Ω and 8 ΩENERGY STAR qualified, efficient Class-D amplifier that conserves energy and requires no active cooling, so it reduces operational costsBridging the outputs provides up to 200W into low impedance, and up to 250W into 70 V or 100 V providing outstanding flexibilityThe ENERGY STAR Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 28 minutes of inactivity, dramatically reducing power consumptionRack-mountable 1U, half rack width enclosureSpecificationsStereo Mode, Watts Per Channel8 Ω dynamic, both channels driven: 60W4 Ω dynamic, both channels driven: 60WBridged Mode, Watts Per Channel8 Ω and 4 Ω dynamic: 200W70 V and 100 V: 250WSignal to Noise (A weighted, 20 Hz – 20 kHz): >100 dBInput Sensitivity: 1.23 Vrms (+4 dBu)Maximum Voltage Gain: 25.0 dBOutput Circuitry: Class DFrequency Response (20 Hz – 20 kHz): +0.1 dB, -0.1 dBInput Impedance:>10 kΩ (balanced)>10 kΩ (unbalanced)Maximum Input Level: +12.3 V (+24 dBu)Highpass Filter: Switchable 80 Hz when bridged in 70 V and 100 VFront Panel Indicators: Power, per channel Signal, per channel Protect / LimitControls: 4 Ω / 8 Ω / 70 V Bridge Highpass, On / 100 V Bridged Highpass, On per channel pairDimensions (H x W x D): 1.7″ x 8.7″ x 9.5″ (43 x 220 x 241 mm)Weight (Net): 3.5 lbs.
