Electro-Voice Q44-II Verstärker

The Electro Voice Q44-II is a solid, reliable amplifier for clubs and diverse mobile applications. It is equipped with a complete safety system that protects it against overloading, overheating, short-circuiting and irregularities in the power supply, so your system can do its job and you can rest easy.

Cooling and Filtering

The Q44-II is cooled with the help of two ventilators, which send the air flow from front to back. The ventilators don't run continuously - making the amplifier exceptionally quiet in standby mode - and their speed can be adjusted in three steps, depending on the temperature. Just like all of the amplifiers from the Q series, the Q44-II is equipped with an LPN filter (low-pass notch). This filter corrects the frequency and phase response of the connected speakers, resulting in a more powerful bass that packs a lot more punch.

Uses

At the rear of the Electro Voice Q44-II is a switch for choosing the amplifier mode. In Dual mode, both channels work independently from one another, which is useful with all two-channel applications, such as stereo or bi-amp. Parallel mode, on the other hand, links the inputs from channels A and B with one another. That means that you can connect your sound source to channel A, and that signal will be sent to both A and B. This function is useful when one signal is driving multiple channels, such as in large (fixed) sound installations. Finally, Bridge mode combines both channels for double the power, and with this mode you can connect the sound source to channel A.
