Professional 1,200-Watt Light Weight Stereo Power Amplifier with ATR (Accelerated Transient Response) Technology
The EPQ Series power amplifiers pack the power of Accelerated Transient Response (ATR) technology into an exceptionally lightweight package. Ample power and high-tech efficiency combine to give you a feather-light supercharged workhorse that will keep your rig kicking for 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. Thatís called Transient Response and itís the holy grail of amp designers. 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 EPQ power amps feature 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, because they are so much more efficient, run cooler and donít require huge, heavy heat sinks
BEHRINGER didnít invent this technology, but our R&D Department has been working for years to perfect our own version, creating lightweight amps that run cool and also achieve our goal of Accelerated Transient Response.Everything You Need
The simple front panel controls of these amps give you all of your soundís 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. A built-in CROSSOVER switch allow you to send low frequency content to subwoofers and other sound reinforcement speakers (CH1<100 Hz / CH2>100 Hz or FULL RANGE). Flick the LIMITER ON/OFF switch to activate the built-in overload protection, or turn it off if youíre feeling lucky
The back panels of the EPQ304, EPQ450 and EPQ900 accept balanced XLR. The EPQ450 and EPQ900 have MONO On/Off and BRIDGE On/Off switches. The EPQ304 has an MONO On/Off switch for INPUTS 1 AND 2, and another MONO On/Off switch for INPUTs 3 and 4.
