Test and calibration tapes for tape recorders – manufactured in Hamburg

🔔 We will be closed for company holidays from March 11–26, 2026 · Your orders will be processed starting March 27 · Thank you for your understanding!

We produce and sell high-precision alignment, test, and calibration tapes for reel-to-reel tape decks, and support you with practical tips and tools for proper calibration.

With our products you can align and calibrate tape decks of all brands, for example AKAI, AMPEX, BALLFINGER, FOSTEX, GRUNDIG, NAGRA, OLIMP, OTARI, PHILIPS, PIONEER, REVOX, SONY, STELLAVOX, STUDER, TANDBERG, TEAC/TASCAM, TECHNICS, TELEFUNKEN and others.

Production is carried out on a highly precise and modified full-track tape machine with extra-wide full-track heads and very low wow & flutter values. Our test tapes are suitable for the alignment of tape decks with different track widths, such as full-track, ½-track or ¼-track, as well as tape decks with different channel counts, such as mono, 2-channel, 4-channel and 8-channel.
 
Selected batches of BASF/Emtec PER368, SM911, PER528, and a very high-quality Quantegy are used for production. In addition, all test and adjustment tapes are individually checked after manufacture.
