Track Format and Tape Recommendations
Tape Type
The Portastudio 414 MKII is internally adjusted for HIGH BIAS Type II tape. This means that for best results, you should only use tapes of this type. TDK SA, Maxell XL-II or equivalent formulations are recommended. We strongly suggest that you select one good quality brand and use it exclusively. The time you spend creating your multitrack master is much more valuable than the money you save by buying inferior tape. The cassette shell essentially becomes a part of the 414 MKII's transport. Poor quality shells can cause wrinkles, snarls and shredding of the edges of the tape with use. Even small scratches on the tape oxide can cause "dropouts" (temporary loss of signal) on one or more tracks. High quality tapes are less likely to cause problems in the long run.
Accidental Erase/Record Protection
To protect a finished master tape, it is necessary to punch out both record protect tabs. Even though you are recording in only one direction, the 414 MKII uses the entire width of the tape. If, for example, you remove only one of the tabs, you could accidentally insert the cassette into the 414 MKII backwards and erase all four tracks of the master.
Tape Length
Use the shortest possible tape for a given work. It is not unusual to play a tape 100 times before you are finished, so select a cassette length that is as close as possible to the length of the program you plan to record. Cassettes C-60 length and shorter are often made from thicker stock than longer cassettes.
The tape used in C-120 cassettes is extremely thin and can cause winding problems, crimping, wrinkling, and other damage to the oxide coating of the tape which will destroy your work. Don't use C-120s in the 414 MKII.
Remember that with twice the normal speed and the "one-side-only" 4-track single direction format, you have only one quarter of the normal play time:
Cassette | Play Time |
| |
C-46 | 11.5 min. |
| |
C-60 | 15 min. |
| |
C-90 | 22.5 min. |
