Behringer EUROPOWER EPQ304 Pro 300-Watt Lightweight 4/Channel Power Amplifier

The Behringer EUROPOWER EPQ304 is a professional 300-Watt light weight 4-channel power amplifier with ATR (Accelerated Transient Response) technology.

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

Accelerated Transient Response Delivers the Knockout Punch
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.

Sublimely Simple Operation
The front panel controls and indicators provide your system's vital signs at a glance. After pressing the Power button, the Power LED lights to show the amp is ready for action. All channels feature positive-detent Gain controls with Signal LEDs that light when a signal is present, as well as Clip LEDs to indicate when the signal is distorted and you need to reduce the input signal. Just as elegant as the front, the rear panel is home to the balanced XLR and 1/4" TRS Input connections, as well as the professional locking speaker Outputs. The same panel contains the switches that put the Channels 1/2 and 3/4 of the EPQ304 in Mono, Stereo (two channel mode) or mono Bridge mode.

Sound Value
The remarkable 4-channel EPQ304 power amp was built for the working musician. It is exceptionally light, packs a massive 300 Watts of output power, thanks to our Accelerated Transient Response (ATR) technology and is built rugged enough for life on the road. Plus, the EPQ304's ultra-light price tag will leave cash left over for you to get more stuff to amplify!
