that's -7dbv

well; I am trying to lock my meters at +3; because 250 nwb/m is standard for my machine but my tape is 355 nwb/m. did I do this right?

it depends on what calibration tape you are using. it will say ate the beginning what level the tones were recorded at

okay;

my manual says to have a 250 nwb/m test tape; calibrated tp 0 db on the VU meters, and .3 V on the output.

but the USR website said for 456 to get a 355 nwb/m tape. so if you have a 355 nwb/m tape, according to the thread I referenced above, you want the vu meters to say +3.

what should the volt reading be on the output?

I think I need a refresher on how to add dBs and convert to voltage.

Gosh, guy! Y'gotta go with the manual, & the website, although well intentioned,... is wrong! I've mentioned that before.;)
 
Ps:...

... and this also shows your deck is running at -10dbV line level.;)
 
one more question - if you bias a machine; can you record over the tape you were using or is it now shot? like, can a strip of tape become overbiased and non-useable?
 
No. Just rerecord over the same tape.

...........;)
 
thanks dave,

ever messed with those bias traps?? I couldn't get a reading on my meter...? the manual doesn't even say what you should be looking for...its pretty vague..
 
yep i have the same problem. my mm says 0.005 or something and nomatter how i change it there is no difference.





wow two threads hijacked with the same issues... not bad going hey...
 
While you were at MRL did you happen to ask them for a quote to do a maintenance on your Otari?
