QSC SPA2-60 2-Channel Compact Power Amplifier, 60W at 4 Ohm, 70V

The SPA2-60 two-channel amplifier delivers up to 60 W RMS per channel into 4 or 8 Ω. The 2 channels can also be bridged, providing up to 200 W RMS into 4 or 8 Ω. When the channels are bridged they can be switched into 70 V or 100 V direct drive mode providing up to 250 W RMS into a mono 70 V or 100 V output. Like the other SPA models, an 80 Hz high-pass filter is engaged when in 70 V or 100 V mode. 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 comes housed in an unobtrusive black painted ½-U chassis with unique mounting hardware enabling rack, table and wall mounting capabilities. Includes SPA2-60 unit Power cable Quick start guide Connector kit Rack mount ears Mounting brackets Features 60 W RMS per channel into 4 Ω or 8 Ω Bridged mode provides 200W RMS into 4 Ω or 8 Ω 250W RMS bridged into a mono 70 V or 100 V output Auto-Ramp provides quiet startup and power-down Class D design conserves energy and reduces operational cost Specifications Stereo Mode, Watts Per Channel: 8 Ω dynamic, both channels driven: 60 W 4 Ω dynamic, both channels driven: 60 W Bridged Mode, Watts Per Channel: 8 Ω and 4 Ω dynamic: 200 W 70 V and 100 V: 250 W Signal to Noise (A weighted, 20 Hz - 20 kHz): > 100 dB Input Sensitivity: 1.23 Vrms (+4 dBu) Maximum Voltage Gain: 25.0 dB Output Circuitry: Class D Frequency Response (20 Hz - 20 kHz): +0.1 dB, -0.1 dB Input Impedance: > 10 kΩ (balanced) > 10 kΩ (unbalanced) Maximum Input Level: +12.3 V (+24 dBu) High-pass Filter: Switchable 80 Hz when bridged in 70 V and 100 V Front Panel Indicators: Power, per channel Signal, per channel Protect / Limit Controls: 4 Ω / 8 Ω / 70 V Bridge High-pass On / 100 V Bridged High-pass on per channel pair Dimensions (H x W x D): 1.7" x 8.7" x 9.5" (43 x 220 x 241mm) Weight (Net): 3.5 lbs.
