1 FEATURES

1. The DN-F20R uses IC memory cards as the recording medium, achieving a highly reliable design with no moving mechanisms. 2. The set uses the MPEG format, an international standard for high compression and high sound quality. 3. The DN-F20R is also compatible with linear PCM recording (WAVE file recording). 4. The set is equipped with XLR microphone input terminals. 5. Despite being equipped with XLR terminals, the DN-F20R is a small A5 size, so it is easy to carry around. 6. IC memory cards containing recorded sources are recorded in DOS (16 bit FAT) file format, so they can be edited on PC systems (*1). (*1) Using an ATA adaptor for insertion into PCMCIA slots. 7. The audio quality (recording bit rate) can be selected according to the application so that cards can be used efficiently. 8. The DN-F20R uses LR6 (AA size) alkaline batteries that can easily be found when traveling.

2 POWER SUPPLY

2 The DN-F20R can be powered using commercially available batteries or the included AC adaptor.

About batteries

[1] Battery type
Use LR6 (AA size) alkaline batteries in the DN-F20R. Do not use manganese batteries, as they may generate heat.
[2] Inserting the batteries

Battery usage time

The set will operate approximately 4 hours on new batteries with one memory card and in the normal recording mode. When the battery power gets low, the battery mark appears on the display window. Once the battery mark appears, the set can used for about 10 more minutes. Replace the batteries with new ones soon. The usage times are rough guides, and may be longer or shorter depending on the temperature and the type of battery. Be sure to turn off the sets power and unplug the AC adaptor before replacing the batteries. If the set detects that the battery power is low within several minutes after the power is turned on, the power may turn off immediately.

8 RECORDING

2 Pay attention to the remaining time when recording on a partially recorded card. We recommend backing up the partially recorded card beforehand using a PC system (not included), etc. 2 If you wish to record on an already recorded card from which you will erase unnecessary files, erase the unnecessary files first. (See pages 25 and 26.)

Starting recording

The DN-F20R offers two types of recording onto IC memory cards: normal (relay: 1/2 or 2/1) recording and double (1 & 2) recording. Set the card recording mode beforehand in the preset mode. / / 2 Normal (relay: 1/2 or 2/1) recording This is the normal recording mode. The sound is recorded onto either the card in slot 1 or the one in slot 2. When the end of the recordable time on the card in slot 1 is reached during recording and a card is loaded in slot 2, recording continues (relays) on the card in slot 2. Start of recording Slot 1 (or 2) card full
Slot 1 (or 2) Slot 2 (or 1)

REC STOP

STOP REC
For relay recording, load the card in the other slot at least 30 seconds before the recordable time on the card currently being recorded is up. If the next card is loaded when there is little recordable time remaining on the card currently being recorded, the set may not have enough time to check the card, in which case recording will not be relayed and the stop mode will be set. If recording is not possible on the card in the next slot, recording stops once the recordable time on the card currently being recorded is up. Recording is not possible if there is no remaining recordable time on the card or if the card already contains the maximum number of files. A message is displayed in the dot matrix section if recording is not possible. Relay recording is only possible in the same directories on the cards in slots 1 and 2. Relay recording is not possible if that directory on the card in the next slot already contains the maximum number of files. 2 Double (1 & 2) recording In this mode, the cards in slots 1 and 2 are recorded simultaneously. Use this mode to make backups of audio files as you record. If audio files are already recorded on one of the cards, recording stops once that card is full. Start of recording Slot 1 (or 2) card full Slot 2 (or 1) card full

REC REC

STOP STOP
When the recording mode is set to double (1 & 2) recording, recording is performed with the same file names in the same directories of the cards in slots 1 and 2. Recording will not start unless recordable cards are loaded in both slots. To record on one card only, preset the recording mode to normal recording. With double recording, the cards are accessed at high speed, so be sure to use recommended IC memory cards of the same make, the same model (capacity) and the same cluster size (even when the cluster size has been changed on a PC, etc.). As long as the cards manufacturer and cluster size are the same, recording may be possible even if the models (capacities) are different. If recording is not possible, either recording will stop or an error message will be displayed when recording starts.

Recording formats (compression/decompression and stereo/mono)
The DN-F20R offers a choice of three recording compression/decompression formats (linear PCM, MPEG1 Layer 2, and MPEG2 Layer 2 LSF see below) and the choice of stereo or monaural recording. 2 Linear PCM Recording is performed without compression, with a sampling frequency of 48 kHz and a quantization bit number of 16 bits. This recording format offers the maximum sound quality possible on the DN-F20R, but the quantity of data per unit time is large, so it uses up much card space. Because the quantity of data per unit time is large, the card access speed must be high. Recording in linear PCM may not be possible on IC memory cards with small cluster sizes and capacities of 16 MB or less. If recording is not possible, either recording will stop or an error message will be displayed when recording starts. 2 MPEG1 Layer 2 Recording is performed with a sampling frequency of 48 kHz and a quantization bit number of 16 bits, but with compression, so that the quantity of data is about 1/6 to 1/12 that of linear PCM recordings. With this mode, the card space can be used efficiently. 2 MPEG2 Layer 2 LSF (Low Sampling Frequency) Recording is performed with a sampling frequency of 24 kHz, a quantization bit number of 16 bits, and compression achieving a data quantity of between about 1/12 to 1/48 that of linear PCM recordings. Because the quantity of data per unit time is small, the frequency response is set to about 11 kHz, reducing the frequency band of the compressed data to maintain sound quality. With this mode, the card space can be used at its highest efficiency. 2 Stereo/monaural Stereo or monaural recording can be selected for all three compression/decompression formats. With monaural recording, the file size is half that of stereo recordings. 2 Setting the recording format (compression/decompression and stereo/mono)

Press the ENTER button. The recording format mode is set.
Press the ENTER button. The selection is stored and the stop mode is set.

Recording bit rates

With the DN-F20R, the bit rate can be selected as described below for the different recording compression/decompression formats. 2 Linear PCM The bit rate is fixed to 768 kbps per channel. 2 MPEG1 Layer 2 The bit rate can be set to either 128 kbps or 64 kbps per channel. Lowering the bit rate lowers the sound quality, but also reduces the file size. 2 MPEG2 Layer 2 LSF (Low Sampling Frequency) The bit rate can be set to either 64 kbps, 56 kbps, 48 kbps, 40 kbps, 32 kbps, 24 kbps or 16 kbps per channel. Lowering the bit rate lowers the sound quality, but also reduces the file size. 2 Setting the recording bit rate

Creating index files

The DN-F20R is equipped with a function for creating and storing separate files, listing the audio files on the IC memory card. This function comes in handy for creating tables of the audio files recorded on IC memory cards using spreadsheet programs on PC systems, etc. With the DN-F20R, these files are called index files. Index files are stored in CVS format. They include the directory names, file names, file recording dates, file sizes, etc.
Select the index file create mode. Press the button to display INDEX FILE MAKE.
Press the ENTER button. A message for confirming that you want to make an index file for the card in the current slot appears.
When the current slot is SLOT1
Press the ENTER button. The index file is created and the stop mode is set.
Press the MODE button if you do not want to make the index file.
It is not possible to view the index file or its contents on the DN-F20R. Files recorded or deleted after creating the index file are not reflected in the index. If you wish to reflect these files, create a new index file. Index files can only be created for audio files located within the standard DN-F20R IC memory card directories. The index file is only created for the card in the current slot. To create index files for the cards in both slots, first create an index file for one card, then use the CARD button to switch the current slot and create an index file for the other card. It may not be possible to create index files if there is not enough space left on the card or if there is a card error. If there are many audio files, it may take 30 seconds or more to create the index file. Never turn the power off or remove the card while the index file is being created.

This is displayed when there are no more files in the direction in which you are trying to move during file searching, etc. This is displayed while an index for the card in the current slot is being created. Never eject the card while this message is displayed. There is no card in that slot. The current directory on the card in that slot already contains the maximum number of files. The card in that slot is already full to capacity. Change the directory for that slot. Due to system restrictions, it is not possible to divide the file at that point. Double recording is not possible because the cards are of different types or formats or have different cluster sizes.

Error messages

If there is an error while using the set, an error message consisting of a number (ERROR = (error number)) appears on the display. This number indicates the type of error. The error numbers are 4-digit numbers. Their meanings are described below. If an error arises, it is necessary to take some sort of action, such as turning the power off then back on, formatting the card (note that this will erase any data on the card), replacing the card, etc. Sometimes the error can be resolved by ejecting the card. The message may differ according to the situation. Description of errors 2 left digits Error no. 01 to to to 99 Description Card-related errors Errors arising during operation System errors 2 right digits Error no. 01 to 03, 30 to 59, A0 to Band and 70 to and to 69 C0 to E9 Specific 4-digit errors Error no. 0304 Description Standard DN-F20R directories cannot be created. If many files and directories (a total of over 255) are stored in the root directory using a PC, etc., the DN-F20R cannot create the directories it requires. If this happens, reduce the number of files using a PC, etc. An error is generated when: there are 1000 or more audio files in the current directory of that card. there are a total of over 1023 files, including non-audio files. If this happens, reduce the number of files using a PC, etc. File type error. (xx = any numbers) The FAT or specific files on the card are damaged. Either erase the files or reformat the card. The index file cannot be created due to insufficient card space. Make extra space by erasing some files, etc. The card has been ejected while it was being accessed. If this message appears each time the power is turned on, the card is damaged. Reformat the card. Note that in some cases the card becomes unusable when this error is generated. Description Card access errors Directory already contains the maximum number of files File type error Card full error Decoding error Data errors Microprocessor errors File over errors Memory card errors Memory card format errors

As shown above, it is possible to create the same functions as the buttons on the DN-F20R by using a 2.5 plug and external circuit. Resistance error Within 5%. Be sure to leave channel 2 open. Never apply external voltage. Doing so will result in malfunction. Normal operation is not possible when transistors, etc., are used instead of switches due to the circuit resistance. Insurate the circuit so that it cannot be touched directly. Use a structure that protects the circuit from static electricity, which will cause malfunction. Do not operate the switches at the same time as the buttons on the set.
