QSC SPA2-60 2-Channel Compact Power Amplifier, 60W at 4 Ohms, 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.
