Designed for use in a wide variety of applications, including touring monitor racks, the E4-75 is a 4-channel amplifier capable of producing 750W/channel into 4 or 8 ohms.

The E4-75 has automatic impedance sensing and changes the power accordingly. Inputs are via four XLR sockets, which can be linked to the next channel via a rear panel switch providing greater flexibility to supply more speakers with the same input signal.

In addition, the E4-75 also has five-segment LED metering for each channel and an indicator to signal 4 or 8 ohm load.
