What to do with a Blank analog tape?

If you followed the first two parts of the series, by now you shouldhave aligned repro and/or sync (Playback) with the alignment tape. Now,put up a blank tape; set the oscillator to 10 kHz and press Record onall tracks. On a three-head machine, if the high-frequency tones wavermore than 1 dB, do NOT pass Go!

How do you set bias on analog tape?

In many cases the service manual will show how to set biasby measuring the voltage at a test point. This method works assumingyou have a voltmeter that is accurate at bias frequencies (the Fluke8060A) and that the heads are new or recently relapped.

How to record bass sweep on analog tape?

Print that tone on tape and note it on the box.Include the bass sweep if the tape becomes a mix master. On a two-head deck, record bass sweep, “PAR,” noting the peaksand dips, then select a low frequency that falls on “0 VU.” Print thattone (on tape) and note it on the box.

Which is more sensitive magnetic tape or analog tape?

Magnetic tape doesnot have the same sensitivity at all frequencies, but when adjustingbias current, high-frequency output is most affected, hence its use inachieving the most precise adjustment.

Are there any pedals that can replicate analog tape delays?

Countless modern pedals and plugins strive to replicate the unique and classic sounds of analog tape delays, and many do a fantastic job. But the subtle idiosyncrasies of tape, magnets, and reels add up to an organic sound that can never quite be replicated by modern technology.
