FLX-E Series
Ethernet-DSP Ampliers
The FLX-E Platform is the most versatile 1/2 rack Ethernet controlled
amplier Stewart has ever produced. This compact package contains
over 300 watts of power output in various channel congurations
and impedances. At the heart of the platform is a robust, internal
full function DSP that is designed to solve a multitude of your audio
problems in just one box. The channel count varies from 1-4 channels
and the DSP allows further conguration via routing, EQ, lters,
limiters and much more. A Ethernet port makes programming, control
and load testing simple, fast and repeatable for large installations.
The RVC and RS-232 are also available for control from a wide range
of devices. In addition, the FLX-E platform has an optional factory
installed Dante™/AES67 card with 4 channels of networked audio in
and out. You won’t nd a more exible combination of power output
and processing in a comparable package on the market today.
