Kenwood DX-7 instruction manual Subcodes, ST-IO Start

Subcodes

With OAT tapes. in addition to the recorded music signal. various subcodes are recorded on the tape to aid in music selection and editing.

With commercially available OAT music tapes. subcodes are prerecorded on the tapes. With blank tapes that you record yourself. subcodes are automatically recorded during recording and can also be recorded manually during editing.

• ST-IO (Start 10)

This signal is recorded at the beginning of each tune. By searching for this signal, the unit can lo- cate the beginning of a designated tune.

Also, the tune number for each tune is written on the tape at the same position as the ST-IO. There- fore, if the ST-IO is not written at the proper pOSition, the tune number will not be displayed correctly.

•The ST-IO is automatically written on the tape during recording in the following cases:

1.When sound is detected again after a blank section of 2 seconds or longer occurs during recording.

2.When recording starts and sound is detected after recording was stopped or paused.

•Depending on the contents of the source being recorded, ST-IOs may not be written correctly on the tape (in cases such as when there is excessive noise between tunes, when the interval between tunes is short, when the sound stops and then starts again in the middle of a tune, or when a tune contains a section of extremely low level sound!. In such cases, you will need to edit the subcodes later. (See page 24.)

•A ST-IO cannot be written within 9 seconds after the previous ST-IO.

•ENO-IO

This signal is recorded to indicate the end of the recorded contents. The unit stops automatically when this signal is detected during playback or fast-forwarding.

This signal is also handy for quickly locating the end of a recording when continuing a recording from the end of the previously recorded contents.

•If recording is continued from the end of a previous recording that has no ENO-IO, the total elapsed time may not continue into the newly recorded section.

In such a case, the total elapsed time for the newly recorded section will not be displayed and the tune search function may not operate correctly. Always write an ENO-IO at the end of a recording.

•Make sure there is at least 9 seconds between the last ST-IO and the ENO-IO.
