ATR-100 is down 3dB at 35 KHz, at 15 ips no less. Mind
you it drops like a rock after that, but it means flat
phase response out to 20 KHz. --scott
Just guessing but probably the only way to obtain that sort of response @ 35
KHz is to record the tone at -10 or -20 dB, rewind the tape, and adjust the
playback head while you measure the recorder's output. Good chance that the
played back tone will have a random bounce of serveral dB.
Will you get that sort of performance if you use yesterday's adjustment of
head azimuth? ;-)
Is the so-called flat phase response from the ATR 100 as good as those shown
here?
