Which calibration tape?

Well Victory Pete, If you are willing to do that for me, I would very much appreciate it. I can load up the original Teac YTT 1144 reel with 10 minutes worth of EMTEC SM911, mail it to you (I will include a postal money order for return shipping). What do you think? If you agree, P.M. me with you address, and I'll get the ball rolling.

Yes well, laziness (and a flight of stairs) forced me to come up with another solution! I have a recently calibrated MS-16 with the same type test tape. I could play back tracks 1-4 and 13-16 to reform the "Fringing Compensation" symmetry. I think that would be just as accurate.

Okay, I dont think we need 10 minutes of tape. These are the short tapes, they work well. I will see how long they actually are.

A 5 minute tape would be good. The test tape is only 2:43 but it is good to have blank tape at each end so it doesnt run off the reels. The MRL tape is cut too close to the ends and it frequently runs off, very annoying. I have recorded the MRL to "Reaper" but cant seem to "Attach" the file, could it be because I am using the 30 day trial period?

VP
 
I am going to try to attach it using the program that came with my HP. not working, I guess you cant attach audio files?

What's the best way to get calibration tape for 8-track Fostex-machines?
Would love to learn the art of calibrating soon.

What do you mean by calculate the appropriate bias? To clarify, bias setting is not something you do with a calibration tape.

I think he is talking about the type of tape the machine uses for recording in general. Such as 456 and 911 are compatible. Then you can select the MRL tape needed for that tape and reference level. This is the procedure I followed for my fleet of Tascams.

VP
 
I meant calculate for the correct reference fluxivity...don't know why I said bias.
There are charts on the MRL website, so even if you don't have the correct tape, you use the charts to calculate/adjust levels to fit your deck or desired fluxivity.
 
Sure. For years I've used the reference on a 185 (O) tape and just calculated the extra db's for a higher level from that.

Waiting for 5 minute blank tape to arrive. I am looking forward to doing this "Experiment". I guess if I can play the tape back on my 2nd calibrated TSR-8 and I get good levels we have a fairly accurate copy of the original test tape.

I recieved the blank tape today, getting ready to procede with this experiment. I am going to make the tape from my recently calibrated MS-16 and record to the TSR-8. I will use tracks 1-4 and 13-16 to reproduce the symmetry of the fringing compensation.

VP
 
There seems to be some minor discrepancies between my MS-16 and TSR-8. I want this to as accurate as possible so I am going to realign both of my machines, I have both teat tapes loaded and I am letting the machines warm up for a while before I procede. I also realized fringe compensation is only necessary when you have a full track width test tape, because I am making a specific 8 track test tape it is not needed. I just have to make sure all levels are 316 mv for all 8 tracks. Apparently when you have a full track tape and you use it for many different track formats you have to compensate the edge tracks. I will keep tweaking until my final copy is 0db across the board.

VP
 
Experiment continues. Apparently the tape stock that was sent is EMTEC 911. I cannot get 0db playback levels, they are down about 3 db. Just goes to show how tape formulations can change widely. I have no experience with EMTEC. I went from 456 to RMGI 911, and that is what is on my test tapes.
