Smart & Connected
The FLX-E(pronounced FLEX-E) Series of amplifiers is the most versatile 1/2 rack amplifier Stewart has ever produced. The FLX-E-80-4-LZ provides 80 watts from each of the four output channels into a 4 Ohm or 8 Ohm load. At the heart of the amplifier is a robust, internal, full-function DSP designed to solve a multitude of your audio problems in just one enclosure. The DSP includes a full cross-point mixer, EQ, filters, limiters and much more. An Ethernet port makes programming simple, fast and repeatable for large installations. The Ethernet, RVC, and Rs-232 interfaces allow volume control from a wide range of devices. You won't find a more flexible combination of power output and processing in a comparable package on the market today.
