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 designers. By carefully selecting transistors with extremely high slew rates and optimizing other proprietary parts of the circuitry, Behringer 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.
The simple front panel controls of these amps give you all of your sound's vital signs at a glance. After pressing the Power Button, the POWER LED will light when the amp is ready for action. Both channels have independent gain dials as well as clip LEDs that indicate when the signal is distorted and you need to reduce the gain. There are also SIGNAL LEDs that light up when a signal is present at the input.
On the back panels of the EPQ2000 and EPQ1200, the INPUTs accept balanced XLR, 1/4" TRS, and unbalanced 1/4" TS and RCA connections. Take your pick of professional locking speaker outputs or touch-proof binding posts to securely connect speakers. The same panel contains the switches that allow you to put these amps to work in either mono, stereo (two channel mode) or mono bridge mode. Flick the LIMITER ON/OFF switch to activate the built-in overload protection, or turn it off if you're feeling lucky.
