Perhaps a bit of finessing of the frequency choice there will yield even better results. It was up a bit at 50, which wasn't too surprising. LF-wise, it was flat at 100 Hz, which is where I'd generally cal it, so I left that alone.
No more HF peakiness (or at least only a little). So I adjusted the HF EQ cal pots to fix it and - voila. So I fixed that, then checked 1K for level, then 10K again, and it was still a bit up. So first I checked bias (cool that they give you complete alignment controls!) and it was, also unsurprisingly, set too low (if we assume the usual 3 db over 10K ips thing). In PT I set up a 'signal generator' plugin to feed the stereo aux that had the ATR plug on it, and was not too surprised to see that it was up about a db at 10K. (I should add that I'm a long time analog guy, and used ATR 102s many times back in the day - it was my absolute favorite mixing deck.) So I did what I'd do with any tape machine: I calibrated it with tones. The LF could certainly be explained by head-bump emulation, but not the top. Using the default settings, except for turning off the noise and crosstalk (456, +6, 1/2") I was again surprised, as I had been in previous, more informal trials of it, that it sounded quite hyped in both top and bottom. I'm still demo-ing the ATR plugin (3 days left), but tried it yesterday for the first time on a new mix I started from scratch.
