To change a menu value, turn the MULTI DIAL (main

unit) B or press the SKIP keys (remote control) I.

The value will change immediately.

To return to the previous screen (before the menu

was entered), press the MULTI DIAL (main unit) B

or press the ENTER key (remote control unit) 8.

Default settings

The default settings when the CD-RW4U is shipped

from the factory are given below.

Signal (trigger or threshold) level

The signal level which may be used with synchro-

nized recording operations (here called the “trigger

level” or “threshold”, is set as below:

1With a recordable disc loaded, press the

MENU key (E or 7) until the display shows:

S_LVL> xxdB, where xx is the cur-

rent value.

2Turn the MULTI DIAL control B or use the

SKIP keys Ito change the value between

MIN L, DD, -24, -30, -36, -42, -

48, -54, -60, -66, and -72 dB.

Low numerical values of this setting (towards –24)

mean that it takes a louder signal to trigger the start

of the synchronized recording. A high numerical

value (towards –72) means that a relatively quiet sig-

nal will trigger the start of recording.

The MIN L is a special case. It means that any

non-zero digital levels (that is, any sound over the

zero level) will act as the trigger signal. It also

applies to analog sounds passed through the AD

converter.

The DD setting is also a special case. It is not a sig-

nal level, but refers to the start of a track, as encoded

in an SPDIF digital audio signal. It is therefore only

used when a digital input is received on the digital

inputs.

NOTE

If the CD-RW4U is used to record a digital audio source

which is connected using analog connections, even if the

setting above is made, the trigger level will automati-

cally be set to

-54

dB.

Also note these points when making digital recordings from

a CD player or a DAT player when using the

setting.

Since the

setting pays no attention to the sound level,

but only to received subcode, it is possible that when the

CD-RW4U is in record ready mode and a CD is selected as

the digital recording source, and the source CD is

changed, when the source player reads the TOC of the

source disc, when the first track is read, a spurious signal

will be sent to the CD-RW4U, which will start recording.

Also, when a digitally-connected DAT is used as the

source, and the tape is wound fast (forward or backward) to

cue the source tape to the start of the desired track, you

should remember that START IDs will be sent from the DAT

deck while the fast wind is proceeding. These START IDs

will also trigger recording if the CD-RW4U is in record

ready mode, and the

setting is selected.

For these reasons, we suggest that you only switch on the

setting when the source CD player or DAT deck is in

STOP mode.
