Alignment tapes, aka calibration or reference tapes, are required to properly set play back on any given tape deck. The alignment tape contains various signals, and array of frequencies, that let the operator setup a tape deck for playback prior to record alignment. We are an authorized dealer of MRL Tapes, which are very reliable. Please consult our resident experts if you have a question as to what alignment tape you should be using for your deck.

This alignment tape is custom recorded on RTM SM911 by MRL. If you want a different tape, this can be made on another tape, but there are only certain choices.

We can also make longer duration tapes by special order.

PLEASE LET US KNOW IF YOU WANT SOMETHING OTHER THAN WHAT IS MENTIONED ABOVE!
