ABOUT BALANCED JACKS

qThe balanced output connector uses a XLR connector.

wThe XLR connector for professional use is internally wired in either of the following two systems.

1. USA system (Pin 2 = COLD, Pin 3 = HOT)

COLD w q
ENGLISH	e	GND
	HOT
2. European system (Pin 2 = HOT, Pin 3 = COLD)
HOT	w q
	e	GND
	COLD

eThe SA-14 uses the USA system of 1.

When a preamp or main amplifier adopting the European system is connected using a cable with XLR balanced connectors, the repro- duced signal may be inverted of phase.

In this case, correct the wiring of the one of the XLR connectors on the extremities of the cable to the USA system by exchanging the connections of pins 2 and 3. This will make it possible to play the signal with the correct phase.

ABOUT THE FILTER

Super Audio CDs have a wide playback frequency band of about 100 kHz that is beyond the audible range: this means that their signals contain ultra-high-range components that conventional CDs do not have. A conventional amplifier is often not built to reproduce signals containing these components, and when Super Audio CD signals are output in their original state, noise may be generated, the amplifier's protection circuits may be activated and/or the speakers may be damaged.

To prevent this sort of trouble from occurring, the unit incorporates a filter for attenuating the ultra-high-range components, and the filter can be set STANDARD or CUSTOM using a switch on the rear panel. (This switch is set to STANDARD when the unit is shipped from the manufacturing plant.)

When the unit is to be connected with a next-generation amplifier that supports Super Audio CDs, loosen the screws at the side of the switch, release the protector, and set the switch to CUSTOM for use. This will ensure play with a wider frequency range.

*Use the switch at the STANDARD position if the unit is to be used with a regular amplifier. Otherwise, the amplifier and/or speakers may be damaged.

*Even when the unit has been connected with an amplifier that supports Super Audio CDs, change the switch to the STANDARD position when recording Super Audio CD sound on a tape deck, for instance.

*Do not change the switch setting while playback is in progress. Doing so could generate electronic noise that could damage your speakers, etc.

Playing CD-RW discs

This unit can play back the CD-RW (ReWritable) discs as well as ordinary music CD and CD-R (Recordable) discs.

*The CD-R and CD-RW discs should contain properly-recorded TOC information so that they can be played back. With the CD recorder system, writing the TOC information in a disc is referred to as finalizing the disc. A disc cannot be recognized as a CD disc and played back unless it has been finalized properly. For details, please read the instruction manual provided with a CD recorder.

*TOC stands for Table Of Contents and contains information such as the total number of tracks and total playing time of the disc.

*This unit can play only the discs recorded in the CD-DA format designed for music reproduction. Do not attempt to play a disc containing other data, such as a CD-ROM for PCs, on this unit.

*As the playback of a CD-RW disc necessitates partial change of the player setup, it may take longer time for reading the TOC information than when a music CD or CD-R disc is played.

*The format for CD-R and CD-RW discs is stipulated in the Orange Book, Parts II and III.

Although the two formats are designed to be compatible, some portions may not capable of being played back, depending on the recording unit, the media, and the playback unit.
