Description
The Holy Grail of Power Amps
You've heard power amps a thousand times before. The Behringer EPQ304 is here to challenge everything you've come to expect. Discover more power, sweeter tone, and pristine signal integrity from a unit that can fit into any sized rack.
Since their inception in 1962, Behringer have gone from strength to strength. The EPQ304 builds upon their legacy of excellence, tightening your sound for a crisp audio experience.
Perform with confidence thanks to Accelerated Transient Response. This advanced technology enhances your natural sound by reacting instantly to electronic bass impulses. The result is less latency, and more punch.
Built for Professional Use
The EPQ304 promises powerful amplification without compromise. Your audio will prove interference-free, utilising an efficient power supply and high-calibre circuitry.
Never worry about stopping the show. The EPQ304 comes prepared for the most demanding environments. The power amp prevents overload at high volume with independent limiters. This means reliable protection, always.
Balance everything with ease. The Behringer EPQ304 makes monitoring simple with power, signal, and clip LEDs. You'll always manage your outputs with precision, even when you're low on time.
