The “Relay Red Mode” is set when anything but “OFF” is selected for “Preset RelayRec” 19). When a disc is loaded, the REC monitor mode is set automatically.

Once recording on the first DN-M991R (DN-M991R-1) starts and the disc’s remaining recording time reaches the time specified with the presettings, an REC E.O.M. tally is output and recording starts on DN-M991R-2.

Thus, it is possible to record continuously on multiple DN-M991R’s.

NOTE: The REC E.O.M. tally is output even if an error occurs on the recording component and the component stops.

2. SERIAL REMOTE

3 ABOUT MINIDISCS

2MiniDiscs allow a maximum of 74 minutes (stereo) of recording and playback in a compact size.

There are two types of MiniDiscs: those for playback only, and those for recording and playback.

Playback only MiniDiscs

•These discs are for playback only. Commercially available music MDs are of this type.

•These are laser discs, like regular compact discs.

•Tracks on such discs cannot be edited.

Recordable MiniDiscs

•These are magneto-optical discs on which both recording and playback are possible. Recording is performed through magnetic modulation.

•Re-recording is also possible.

Accidental erasure prevention tabs

These tabs protect recordable MiniDiscs from accidental erasure.

To avoid accidentally erasing the recording, open the tab so that the hole is exposed. (See the diagram below.) When this is done, “Protected” is displayed if you attempt to record, erase or otherwise edit the disc, and the recording is protected. To record or erase the disc, set the tab back to its original position (with the hole covered).

Hole exposed

Recording on discs

MiniDiscs include a section in which the audio signals are recorded and a section in which such data as track numbers and track titles are recorded.

Section in which track numbers and track titles

are recorded (TOC) Section in which audio signals are recorded

2The TOC

With MiniDiscs, after the audio signals are recorded, data used for checking the tracks (TOC–Table of Contents) is also recorded on the disc. This TOC data is used when playing the disc. In addition, editing is performed by rewriting the TOC data.

When TOC writing starts, the “ TOC ” indicator flashes. Do not shake the main unit, press the main unit’s power button or unplug the power cord while the TOC is being written. If the data is not recorded properly, it will not be possible to play the disc.

2Handling MiniDiscs

MiniDiscs are housed in cartridges, so there is no need to worry about dirt and scratches. However, dirty or warped cartridges may cause malfunction. Be careful of the following to ensure long-lasting, high quality sound:

•Do not touch the disc surface directly.

•Do not open the shutter by hand.

•Do not place MiniDiscs in dusty, dirty or humid places.

•Do not place MiniDiscs in places exposed to direct sunlight or high temperatures.

Cleaning

Use a dry cloth to gently wipe dirt or dust off the cartridge. Do not apply excessive force.
