Is there such a thing as a portable, standalone, reasonably inexpensive (< $500), DC-powered word clock? I've Googled without much success, but perhaps I'm using the wrong keywords or some such.
Reason I ask: I'm evaluating options for multi-channel (well, really dual stereo) recording, and leaning heavily towards an R-4. But I wonder whether I could run 2 x V3 as long as I'm able to sync them to the same word clock, thereby enabling easy mixing in post.
