(None of this is anything to worry about unless you are dealing with music and people with perfect pitch. The nominal line up tone frequency is usually 1kHz so, if your calculations are correct, either the Nagra was running a little slow, your machine is running a little fast or the tone oscillator was a fraction off. I can't be bothered to do the maths but I think that equates to 0.2 mS at 10kHz (which is the point at which azimuth is usually checked.) From that you can work out the phase error if your brain works that way.Īll you are doing with this adjustment is removing the difference in azimuth between your machine's replay head and the Nagra record head. To be honest, with that small an error you are unlikely hear a difference. Your post implies you are playing a full-track (ie 1 track) tape back on a 4-track machine :confused:
