Electro-Voice’s philosophy is that tonal performance of live music counts most; therefore, Electro-Voice amps are designed for dynamic headroom, meaning that each and every EV amp-including the Q44 II-has at least 30% more output capability for short-term signals when compared to a long-term sine wave value. This additional headroom results in an amp that will, for example, allow for short term signal peaks of at least 780W when spec’d 600W. While dynamic headroom is audible when playing music through a sound system, another specification to observe is the increase in output power from an 8-ohm load to 4 ohms, and then down to 2 ohms. Of course, all EV power amplifiers are designed to be absolutely stable into loads of 2 ohms.

• Both inputs on the EV Q44 II have a paralleled loop thru XLR output to route signal to other amp inputs
• Besides the usual channel A & B outputs via Speakon connectors (on pin 1+/1-), output A carries the signal of channel B as well (on pin 2+ / 2-), providing an easy drive option for biamped speakers
• Parallel & Bridge Mode option switches provide additional functionality with minimized cabling requirements
