Product description Electro-Voice Q44
When two speaker channels are to operate independently or deliver more power together, the right operating mode determines the wiring. The Electro-Voice Q-44 is a two-channel PA power amplifier for mobile systems and club installations, with Dual, Parallel and Bridged operation.
In stereo mode, it delivers 2 x 270 watts at 8 ohms, 2 x 450 watts at 4 ohms or 2 x 650 watts at 2 ohms. In Parallel mode, both channels receive the same input signal, while their levels can still be adjusted separately. In Bridged mode, the two channels are linked; up to 900 watts at 8 ohms or 1,300 watts at 4 ohms are possible. The connected load must not be less than 4 ohms in Bridged mode.
The switchable LPN filter corrects the frequency and phase response of the connected speakers and optimises the signal's transient response. You can compare the effect directly with the filter switched on and off. The adjustment can produce a more powerful sound, particularly with full-range speakers and subwoofers; filter operation is not recommended for larger systems controlled, for example, via an EV DC-One.
Two electronically balanced XLR inputs and one parallel XLR output for each input are available for signal routing. Two Speakon outputs carry the speaker signals; in Dual or Parallel mode, channel A can also be used for bi-amp wiring. The Groundlift switch helps prevent hum loops. The inputs are balanced; when using an unbalanced connection, short cables and the correct bridge in the plug are important, otherwise the level may drop by 6 dB.
A dynamic limiter and protection circuits against overheating, DC, short circuits, RF, back EMF and overcurrent protect the power amplifier and connected speakers. Inrush current limitation and delayed speaker connection add to the protection features. Two temperature-controlled fans operate at three speeds and move air from front to back. For rack installation, the air intake and exhaust must remain unobstructed; continuous operation at 2 ohms depends on the ambient conditions.
With Class AB power amplifier technology, a 19-inch rack format and a weight of 12.6 kg, this model fits into mobile PA racks and permanent sound systems. Its power ratings, three operating modes, switchable LPN filter and suitable inputs and outputs make it a good choice for setups in which you want to drive speakers in stereo, parallel or bridged mode.
