ElectroVoice Q44-II 650 W/CH Power Amplifier

ElectroVoice Q44-II 650 W/CH Power Amplifier

Electro-Voice Q series amplifiers offer a package of reliable high output power, high efficiency and legendary pro audio performance. They are the premium choice as system drive for a variety of mobile and club sound systems like e.g. ZX, TourX and Phoenix loudspeaker families. Their comprehensive protection system includes circuitry against overheating, overload, short circuit, HF and DC as well as back-EMF and inrush current. Loudspeakers are protected by turn-on-delay relays.
The build-in patented LPN (Low-Pass-Notch) filter compensates for transient distortion in dynamic signals (such as kickdrums) to achieve a higher acoustic output and more punch.
