Which Tape is Right for You?

Posted on by

We are sorry that Cobalt tape is no longer available, but the other three types are very high quality. Please choose the best tape for your recording.

  1. MUSIC FERRIC tape has a frequency response of 50 Hz to 16 kHz. Ferric tape offers deep “booming” bass, “warm” mid-range and excellent high frequencies up to 16 kHz (the upper end of most people’s hearing range).
  1. CHROME tape is a special tape weighted toward high frequencies. Frequency response is 100 Hz to 20 kHz. Chrome also offers +4 db output compared to Music Ferric. Although bass performance is not quite as good, Chrome offers the same midrange and exceptional high frequency response. It is recommended for music with synthesizers, electronic “soundscapes” and other unconventional instruments.
  1. CHROME PLUS “CP-EXTRA” tape is the ultimate Type II audio tape designed for high-speed duplication. With uniform output from 50 to 20,000 Hz providing better tone balance, CP-Extra is the best choice for music recordings. CP-Extra is up to 4 decibels “hotter” than other chrome tapes.

Description of Dolby B
Dolby is an encoding of the audio intended to only reduce the tape noise on the copied tapes, while leaving the original audio (including any “unwanted noise”) unchanged. It will not “fix” the sound of the master. We do not recommend Dolby on duplication unless you are sure the listeners will have Dolby settings on their playback equipment.

To further explain:

The original master is run through a Dolby encoder that basically boosts the upper frequencies while the audio is quiet, and doesn’t boost as much when the audio is loud (relative to a set threshold). The copy tapes are duplicated with this encoding of shifted frequencies; and when played back in a deck with Dobly B engaged, the decoder reverses the boosts that were added to the original audio by the Dolby encoder according to the program levels that it senses. The result should be that the original audio sounds unchanged, but the tape noise (most noticeable in the higher frequencies) of the copy tapes has been reduced by almost 10db.
