BEHRINGER EUROPOWER EP4000 Power Amplifier

One amplifier, three ways to drive your speakers.

The mixer is set and the speakers stand ready. The EP4000 is the power between them, in two units of a 19" rack. MODE switches on the rear panel set the operating mode, the limiters and the high-pass filters.

Stereo, parallel or bridged

In 2-channel mode, each channel has its own input signal. Parallel mode feeds one input into both outputs. Each channel then keeps its own amplification, filter and limiter settings. Mono-bridged mode adds the voltage of both channels to drive a single 8 or 4 ohm load. Never apply a 2 ohm load when bridged.

Filters and limiters on each channel

Each channel has a clip limiter that you engage or disengage. It lowers amplification until distortion is reduced to a tolerable level. A high-pass filter removes frequencies below 30 or 50 Hz. The 30 Hz filter suits subwoofer operation. With broadband speakers, engage the 50 Hz filter.

Connections and cooling

Each channel takes balanced XLR or ¼" TRS. Speakers connect through two speaker connectors or two pairs of touch-safe binding posts. Fan speed adjusts automatically, and hot air leaves at the front to relieve the rack. A BREAKER replaces discardable fuses: clear the fault, switch off, press it and power up again.

Features

• Stereo power amplifier: with ATR (Accelerated Transient Response) technology
• Rack mounting: installs in a 19" rack and takes two rack units
• Rear-panel MODE switches: set the operating mode, the limiters and the high-pass filters
• Stereo mode: both channels work independently, each with its own input signal
• Parallel mode: one input feeds both outputs, with independent amplification, filter and limiter per channel
• Mono-bridged mode: adds the voltage of both channels to drive a single 8 or 4 ohm load
• Clip limiter: can be engaged or disengaged and lowers amplification until distortion is reduced to a tolerable level
• High-pass filters: remove frequencies below 30 or 50 Hz, with 30 Hz suited to subwoofer operation
• Balanced inputs: XLR and ¼" TRS jack inputs on each channel
• Speaker outputs: two professional speaker connectors and two pairs of touch-safe binding posts
• Front-exhaust cooling: fan speed adjusts automatically and hot air leaves at the front to relieve the rack
• Breaker instead of fuses: after the fault is cleared, press the BREAKER and power up again
