Electro-Voice Q-Series Amplifiers: Hi, my name is Josh Bartunik. I’m a product manager for Electro-Voice, and I’m here to talk about the brand new series of Q-Series amplifiers from EV. Now, this is actually Mark II when it comes to the Q-Series. Originally, we offered the Q-44 and theQ-66 in three rack space units. This time around, we actually launched some additional products. We made some revisions, some updates, and some aesthetic updates to this product, and we’re launching a whole family of amplifiers that cover virtually every range in the retail market. Two rack space, Q-44 and Q-66, and then we add to the line with the Q-99 and the Q-1212. As far as wattage is concerned, Q-44 is 450 watts at four ohms, Q-66 is 600 watts at four ohms, the 99 is 900 watts at four ohms, and the 1212 is 1200 watts at four ohms. These amplifiers are actually entirely two ohm stable, which a lot of competitive products simply can’t do, so they’re designed with top quality components that allow you to actually go to two ohm stability and really put more loud speakers on these amplifiers and make them work without overheating or shutting down or actually providing distortion. One of the other feature sets that is involved with these amplifiers is a patented circuit design that we have called LPN, or low pass notch. Fundamentally, what a low pass notch does is it compensates for the fact that a woofer has to accelerate to match the transient of an amplifier. What happens is when the woofer accelerates, you lose some amplitude and your frequency actually changes of the transient. This circuit actually injects some voltage into that circuit and allows it to compensate and add amplitude to the transient and nothing else. So the perceived sound quality is a boost in punch, a boost in low frequency that is very clean and very noticeable.
