What's a good test signal to match two decks' azimuth with?

Hi everyone

I've been using a cassette deck again for the past few months and would like to play my tapes in a couple portables I've got.

I was wondering what a good test signal is, something that will make it real easy to set azimuth by ear using just a tape with that signal and a screwdriver, as I've got no other equipment.

I find that I'm not particularly sensitive to small variations in steady tones, otherwise I'd just use a 10 kHz tone from a test tape. I've also tried using music with lots of HF content but I can never be sure if I've nailed it.


Thanks!

10Khz is fine. If you have a scope you can adjust a little bit better but I recall setting azimuth on average decks by ear with good result.

Make a record of white noise (-20dB) then playback this noise on portables and adjust their azimuth by ear for the "sharpest" noise.

Hi,

as suggested interstation noise from your fm tuner is probably best.

Yes that's it. FM interstation noise is like white noise.
