The Technical Pro L4Z4001 4-Channel Power Amplifier is a 2RU 19" rackmountable amplifier that delivers 4000W of peak power for live sound reinforcement applications. Each channel is rated to 1000W at 2Ω, 660W at 4Ω, and 350W at 8Ω. The unit is bridgeable from four to three or two channels for distributing the power as the application requires. The front panel of the unit features a power on/off switch, four gain knobs, and four sets of blue LED meter clipping indicator lights.
The unit features both 1/4" TRS and RCA inputs on each channel. For outputs, each channel features a pair of banana binding posts and a Neutrik Speakon connector. Channels 1 and 2 as a pair and channels 3 and 4 as a pair can be set to stereo or bridged mono mode using the two stereo/bridged mono switches on the back of the unit. A ground/lift switch can be turned on or off to eliminate the effects of ground loops.
