Fluxlevel and Maximum Operating Level (MOL) Calculator
Welcome to our Flux level Page.
This page will help you to determine the highest fluxivity you can use with different types of Tape and it will make it easier to calculate a particular level with the use of a Test Tape other than 180 nW/m according to the tables below. For alignment instructions please go to the page Alignments.
The two most important terms used are:
MOL: Maximum Operating Level
OPL: Operating Level
The Operating Level can be lower than the Maximum Operating Level, but not vice versa. For a more detailed definition what MOL means please
Level to be shown on VU meter ( Make sure your VU-Meter is calibrated first ! )
How this Table Works
Select your Testtape Fluxlevel of the Tape you own or intend to buy in the left column, than read the results under the OPL (Operating Level) you want to use. The OPL is determined by the Maximum Output Level or MOL of the Tape you are using! The OPL can be equall or less than the MOL. Most People use MOL as OPL. Required that your equipment can handle the higher OPL's. Most TEAC's Playback and Record Amplifier's are to weak to handle anything beyond +3dB (250nWb/m) max. i.e. You want to use:
1) All MOL's are at 1 KHz with 1% distortion at the 3rd harmonic. 2) The glue in these Tapes disolves (breaksdown) as the result of humidity! The result is a huge built up of Tape residue on all Guideposts, capstan, heads etc. in short anything what comes in contact with the Tape, anytime when the Tape is played . The Tape will slow down and will come to a complete stand still. You will have to clean all parts with Alcohol and/or Acetone. You will have to "Bake the Tape" in order to play it back one last time. After that it can go in the trash!!!!!! Do not buy anymore of these Tapes!!!! If you need info on how to "Bake a Tape" than click here!
