Locating the Loudest Portion of__
the Disc - Peak Search Fi
The unit will scan a disc from beginning to end and
determine the loudest portion (peak level) of the disc, and
then play that portion repeatedly. This function will make it
easier for you to adjust to the optimum level when
recording on tape. You can use this function in the
continuous or shuffle play mode only for a disc which is in
play position currently, and in the program play mode for
the selections of the entire program.
To set peak search
Press PEAK SEARCH in the stop mode. “PEAK” flashes
in the window. The entire tracks in a disc or program will
be searched automatically. “PEAK” lights up and the
loudest portion will be played repeatedly for 4 seconds.
Adjust the recording level on your tape deck according to
the peak level.
Note
To go to another disc press DISC SKIP button during stop.
To stop peak search
Press E.
Press Îl to pause at the first selection.
To start play immediately

Note on peak search function
The unit determines the loudest portion (peak level) of a disc
by searching it at fixed intervals. As a result, the portion
searched may differ from the actual peak level. In addition, this
function may determine different portions as the peak level for
the same disc. However, the difference between the portion
searched and the actual peak level is insignificant and will not
present any problem in adjusting the recording level.
