Please click on the blue product titles above for more details and the order button. We feature Magnetic Reference Laboratory calibration tapes which are simply the best around. Every studio should have these tapes to make sure the decks are aligned to international standards and are operating at the best possible performance levels. If you're unsure what operating level you're actually recording at or if you're questioning if your deck is really tweaked to perfection or not, you need these tapes. There's no other reliable way to do it.

Use 250 nWb/m tapes for AMPEX/Q 406, 407, 478 and 480. Use 355 nWb/m for AMPEX/Q 456, AMPEX/Q 499, RMGI-EMTEC SM911, SM900. For RMGI SM900, ATR MDS-36, ATR Master Tape, AMPEX/Q 499 and GP9 set repro level to -3 for initial operating level calibration.

Each multi-frequency tape contains  the following contents in this order: Reference Fluxivity: 1000Hz Azimuth, Phase & Prelim Response: 500Hz, 8kHz, 16kHz Amplitude & Frequency Response: 32Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 10kHz, 12.5kHz, 16kHz, 20kHz Reference Fluxivity (final): 1kHz

All our MRL calibration tapes are now shipped on ATR Master Tape stock due to its reliability but, of course, you can record on any tape you want. ATR sets the standard.
