Accelerated Transient Response

Transient Response is paramount when it comes to amplification design. By selecting the appropriate transistors with high slew rates, the speed that electricity is served to the woofer cone improves dramatically. It takes a lot of electric energy via the current and voltage to propel a woofer cone to match the bass beat as its triggered. The ATR (accelerated transient response) technology is designed to improve the speed of the pulse, giving your amp the fast response it needs to provide a thick, pulsing low-end. It works by modulating the power supply rails with only the peak of the input signal, instead of operating continuously like most other power amps. This design provides more dynamic punch and improved efficiency, resulting in a cooler running unit because it doesn’t require heavy heat sinks.

Exceptional Audio Quality

The EPQ304 was built with audio professionals in mind, delivering a lightweight yet powerful amplification system that doesn’t compromise on functionality. The amplifier features an array of professional components designed to offer the highest quality audio possible. The ultra-low noise switch-mode power supply delivers noise-free audio and superior transient response, resulting in lower power consumption. There are also independent limiters for each channel offering high volume levels with reliable overload protection. Monitoring is provided by the Precise Power, Signal and Clip LEDs, allowing you to easily check your levels on the fly. Detented gain controls have also been featured for precise setting and matching of sensitivity, giving you even more control over the output level.
