The R6 500 Series chassis features a solid steel construction with an internal power supply that delivers 150% of the power you'll ever demand. With a plethora of connections available, the R6 back panel is practically a patchbay on its own. The R6 features 8 channels of balanced I/O options including DB-25, XLR and TRS that may be used interchangeably. Because the R6 is built to 500 series specifications, it will work flawlessly with any properly-designed 500 series module you wish to include in it. To help accommodate modules that are slightly out of spec, the R6 has variable-position screw holes to help make the installation process as smooth as possible.
