analog for the people!
Because their target market was high-end professional machines which can handle a very high operating level (ATR tape was originally specced as +11 tape IIRC), e.g. Studer, Ampex and Otari multitracks or stereo mastering decks.
Not all machines can actually bias up that high and the TASCAM machines like the TSR and MSR series were intended to run +6 tape (456, SM911 or other equivalents). Maybe the MSR-24 can run at nearly double its factory specified operating level, maybe not. You'd likely get a lot more crosstalk if you did.
Alternatively, you could just leave the machine set to +6 and see what happens if it's fed ATR tape. It might work quite nicely, but I don't think that's how the tape is designed to be used
Nonsense, ATR works fine at +6, though you get a little higher noise floor of course. ATR runs quiet in my experience and you can get away with +6. It's not like the analog world will end if you run a tape a few dB below what it's optimized for. ATR also claims a broad bias tolerance as well. I like to hit it at +9 (I'm using a pro wide track MCI machine) and on my machine at 15ips +9 I like about 3.5db overbias. They claim +10.5 capability but I wouldn't necessarily suggest going that high with a loud percussive source or if there's any risk of your levels getting away from you due to the risk of print through even if the stuff is meant to allow good headroom, may as well go +9 and not have to nanny the levels quite so much. Actually, ATR claims to work well at a variety of levels, that's one nice thing about it. If you're wanting a tape you can smash and get all compressy then ATR probably isn't your top dog anyway, it's pretty clear, spit-shined sounding stuff. Bottom line is if TASCAM MAN is calibrating and biasing for 499 with no prob on his machine then ATR shouldn't be an issue as far as operating level or biasing is concerned.
It's the excessive oxide schmear that you have to worry over. YMMV on that but it's been a problem for me, way too much "hang on guys, the high freqs are getting dull, I have to clean the tape path...again..." I shall be having another word with His Spitzness before I endeavor to roll any more ATR on my machines, what a shame, very nice guy and his tape really does sound superb when the path is clean. Maybe he ought to call it +9 tape and ease up on the freakin' oxide slatherfest, I dunno lol!
But yeah, if you want to run +6 on a tape that's intended for no more than +6 on a +6 machine then SM911 would be the currently produced tape for that.
