Doesn't look like it in photos, but this thing is small. The DS214 is really a great little device to professionally (and simply) add headphone monitoring and level adjustments for microphone inputs to DSLR's. The DS214 even includes AGC Defeat so this little black box can literally work magic for all DSLR audio shortcomings. Love the starting price point too. I'll mount it up next to a camera and show what that would look like.
