How it helps
Use it for a focused task
A practical, searchable reference for tape formulations and their typical bias, equalization, and recording levels. Pick a tape or choose a machine first, then read guidance, save personal notes, or print a wall sheet.
Start by selecting a tape formulation from the list or typing to search. Use the machine filter to narrow results to your recorder.
Read the bias, level, and EQ notes for your selection, then save any personal calibration notes to your browser or print the reference card. Tape bias, level, and EQ settings are scattered across old manuals, forum threads, and half-remembered advice.
