In the meantime, I'm trimming the shafts on the pots down so that the knobs sit at the proper height, and I wired the cue select LEDs. I'm not sure which knobs I'll be using for volume yet, so I am waiting to cut those down. One thing I discovered is that it's extremely difficult to cut something that rotates with a hacksaw, especially if you don't have a vise. The cutting wheel on my Dremel made quick work of the shafts though.
The cueing will be 1 channel at a time, with a blend between cue and master. The channel is selected via a rotary knob. Here's a shot of the LEDs in action, but obviously no audio yet (but at least I'm on track). This is the first visible sign of life from the mixer.
Hey man, did you ever finish this mixer? Thinking of doing my own but finding it very daunting!
ReplyDeleteHi Nick! The mixer is functional now, but not complete. It got shelved about a year ago when I moved, and I haven't dived back into it yet. Right now it's got 4 functioning channels, 2 of which have a phono preamp and high-pass filters (the bass is cut), the other 2 are just line-in (when I started building this the HPF kits were not available yet and I didn't know how big they'd be, and didn't budget the right amount of space). The "vu" LEDs are not in yet either, although they are ready to go so it's a relatively simple matter.
ReplyDeleteAll in all, it was a good learning experience. The hardest part is all the friggin' wiring. The guy who made the kits did an awesome job on the boards but the information on how to wire everything up (board to board, board to connector) is vague at best, and there was quite a lot of that.
I was also surprised by how much I ended up spending on all the little bits and pieces - it ends up adding up. Still a lot less than a Urei or E&S rotary mixer but nonetheless mildly surprising. Of course, once you start building it, it'd be silly to quit before it's functional :)
I'll update the blog with a video of it in action. Still has a couple bugs.
