To clear the edited contents
Press any one of these keys.
The edited data is cleared entirely.

Peak search

This function identifies the highest peak level of the entire recording on a CD before recording the CD on the cassette deck. With this unit, after the peak level of each track recorded on the CD has been searched, the section of the music containing the highest peak level will be played repeatedly so that the recording level of the cassette deck or MD (analog recording) can be adjusted easily. This feature is particularly convenient when using a cassette deck with manual recording level adjustment which does not have the automatic recording level adjustment function. (This unit cannot perform peak search recording when used with a cassette deck equipped with the peak search function.)

PEAK SEARCH

After a high-speed search of all tracks, the searched peak level section will be repeated at normal speed. The peak level is detected by sampling the section which seems to contain the maximum level in the disc. However, it may happen that the transient maximum level is not detected. Therefore, it is recommended to set the recording level by leaving a certain margin above the detected peak level.

To cancel Peak search:

Press the 7 key.

Peak search

This function identifies the highest peak level of the entire recording on a CD before recording the CD on the cassette deck. With this unit, after the peak level of each track recorded on the CD has been searched, the section of the music containing the highest peak level will be played repeatedly so that the recording level of the cassette deck or MD (analog recording) can be adjusted easily. This feature is particularly convenient when using a cassette deck with manual recording level adjustment which does not have the automatic recording level adjustment function. (This unit cannot perform peak search recording when used with a cassette deck equipped with the peak search function.)

PEAK SEARCH

After a high-speed search of all tracks, the searched peak level section will be repeated at normal speed. The peak level is detected by sampling the section which seems to contain the maximum level in the disc. However, it may happen that the transient maximum level is not detected. Therefore, it is recommended to set the recording level by leaving a certain margin above the detected peak level.

To cancel Peak search:

Press the 7 key.
