Please click on the blue product titles below 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,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

The "standard tape stock" option for the below listed tapes is RMGI SM900 or SM911 tape stock and they are shipped directly to you from MRL Lab in California. Each tape also has an option for using ATR Master tape at a slight premium.
