On Reel to Reel both bias and EQ are record only functions and these switches on your deck have NO effect on playback.
On Cassette bias is a record only function however Cassette has two playback EQ settings: 70ms and 120ms, choosing the incorrect one will make the recording sound either too dull or too bright.
Basically if a pre-recorded Chromium dioxide cassette says �Compatible Chrome�, �120us Chrome�, or just �Chrome� with only the small notch removed on the top of the headshell it is 120us EQ (Normal).
If a pre-recorded Chromium dioxide cassette says �70us Chrome�, or just �Chrome� with the large notch removed on the top of the headshell it is 120us EQ (Chrome/Metal).

it's NOTus or uS - docw 10:17:40 01/05/07 (1)
but muS--lowercase μ and here refers to microseconds
Mu is the 12th letter of the Greek alphabet.

  to: 70μS and 120μS.
  Maybe it thought it was "ms" because it stands for microseconds?

NOTE: "ms" should read "uS", thanks for the correction Mike! - Teresa 20:04:57 01/01/07 (0)
I think I have been calling it "ms" for decades when my cassettes clearly say "uS" or "us". I don't know where the "ms" comes from other than my salutation.
Please if anyone sees any errors or typos on my web site me know at info@analoglovers.com.
Thanks,

I hope it is only a typo. If a pre-recorded Chromium dioxide cassette says " 70uS Chrome " or " Duplicated on Chromium Tape, Requires 70uS Eq " with the large notch removed on the top of the headshell it requires 70uS EQ ( Chrome/Metal ) setting during playback in your deck.
Correct me if this is not true.

Regards,
Mike
- Thanks it is "uS" not "ms", I just confirmed looking at my pre-recorded cassettes - Teresa 19:27:15 01/01/07 (0)
  I will change all reference on my web site from "ms" to "uS", great catch.
  I found another error the other day I have "Direct to Tape Recording Company" listed as "Reel to Real recording company". Reel to Real was a company that sold pre-recorded Reel to Reels.
  If anyone else sees typos or errors please email me at info@analoglovers.com.
