Behringer Europower EPQ304 Power Amplifier

The remarkable 4-channel EPQ304 packs a heart-stopping 300 Watts of output power into an exceptionally lightweight (8.8 lbs/4.0 kg) package, thanks to our Accelerated Transient Response (ATR) technology. Ample power (4 x 75 Watts @ 4 Ohms; 4 x 50 Watts @ 8 Ohms) and high-tech efficiency combine, giving you a feather-light, supercharged workhorse that will keep your rig kicking for years and years to come.

It takes huge pulses of energy (current and voltage) to propel a woofer cone out fast enough to match a bass beat. That’s called Transient Response and it’s the holy grail of amp design. By carefully selecting transistors with extremely high slew rates and optimizing other proprietary parts of our circuitry, our amps are able to react instantly to even the most demanding electronic bass impulses. If the woofers in your PA system can keep up, your audience will hear a tighter, crisper, more natural sound. Instead of operating relatively continuously like most power amps, the EPQ304 features rail tracking for effectively modulating the power supply rails with only the peaks of the input signal. This technology has revolutionized pro audio amp designs with its outstanding performance and efficiency. When combined with switching-mode power supplies that do away with heavy toroid transformers, our new designs provide more dynamic punch and, since they are so much more efficient, run cooler and don’t require huge, heavy heat sinks.
