PA 140

Power Amplifier

The QUBE PA 140 delivers 350w RMS per channel @ 8 ohms 500w RMS per channel @ 4 ohms, 1000w RMS continuous bridged mono mode @ 8 ohms. The PA 140 Power Amplifier is for applications where reliability and audiophile sound reproduction are of primary importance. Key features include self-resetting protective circuitry to safeguard against damage and prevent failures, LED indicators for the operation status of each channel, a ground lift switch, a switch for stereo/ mono/ bridge mode operation, balanced XLR ins/outs and Neutrik® Speakon outs. The Qube PA 140 Power Amplifier features a port in the rear of the amp to accommodate optional plug in Qube controller modules, which are specially designed to optimize the sound and performance of Qube passive version speakers and to protect them from damage and failure.Continuous power both channels driven (WRMS) 350 W 8 ohm - 500 W 4 ohm @ THD < 0,05%
