Onix Rocket Digital Equalization System (R-DES) Introduction

I'd seen pictures of the R-DES on the AV123 website but I still wasn't prepared for it when it arrived. It was so - small. And light. I almost shook it to see if there was anything in there. The case has an industrial look that I find very attractive. There are two buttons in the front and six lights. The button to the far left switches the unit between on and standby (when it is in standby mode, the sub is disengaged). The far right button switches between the four presets and the bypass mode. In between the two buttons are the lights to indicate which mode you are currently using (in order from left to right - Bypass, Preset 1, 2, 3, and 4). The aluminum body has inset lines running the depth of the unit on the sides but not the top and bottom. The black rings around the unit near the front and back plates are made of a hard plastic.
