i felt like i was hijacking too bad so i started a new thread. I ran into a problem.
First I did MCI2424's azimuth test and everrything looked good. Then I followed the instructions in the manual. I am trying to set up my machine for 456 and I have a 355 nwb/m tape. So, I think I need to be referencing the tape playback to +3 db on the VU meters, which I think is .446 volts.
So I have adjusted the tape playback to read .446 on both channels on both the sync and repro heads. I then adjusted my meters to read +3 on the same playback. This was all with the 1khz tone. I then adjusted the repro and sync playback eq to +3 on the VUs using the 10k tone.
The next part is where I got stuck. I am sending a tone out of my PC to check the input level calibration. The manual says to use 400 hz but I have tried 400 hz and 1khz with the same results. I have measured the tone coming out of my soundcard to be at .3 volts. When I input it to either channel of the machine, set to monitor the inputs, both channels read 0 on the VU's. perfect. The L output also reads .3 V as it should. But the R output is reading closer to .4 V (about a 2 db difference)
The manual had said to set the input level by either looking at the VU's OR checking the output voltage. The first one is working and the second one isn't. so I am concerned something is off. I went back and started all over again and everything is the same. and I did start off by cleaning and demagging so I can't think of the problem.
