I have a small complaint about the GL2800 after tonights gig, and I noticed it is common among several over A&H boards.
The GL2800 and other A&H boards have sides on them that are just the sheet metal from the bottom bent up. This creates a problem. When you go to pick it up and set it down you have to hold it from the bottom, but when you need to set it down there is nothing to grab onto so the only way to put it down is lower it down with your fingers getting scrushed between the table and the board, and then slide your fingers out and let the board drop.
Picking it up presents a similar problem, There is nothing towards the back of the board to get your hands under to pick it up.
This seems like a petty complaint but it is kind of an inconvenience. Presumably most people will have it in a flight case but if it is ever pulled out it is hard to move. My soundcraft lx7ii has molded plastic sides with a little recess to get your hands into to pick it up. Much easier to sling it around.
Plenty of handles on a piece of pro-audio gear is always a good thing.
