HINT

The above setting is stored as part of the stereo mode settings.

Converting WAV files into MP3 files (stereo mode only)

You can convert a WAV file recorded in stereo mode into an MP3 file. Compared to a WAV file, the file size of an MP3 is much smaller, because the content is compressed. This is convenient for example to place recorded content on a web site or send it by e-mail.

NOTE

Depending on the type of card and the recording format, the conversion process may take about as long as the recording time of the source file. The unit should therefore be powered from the AC adapter during the conversion. Sufficient free space will also be needed on the card.

1. At the stereo mode top screen, press the center of the [MENU] key.

The main menu which gives access to various H4 settings appears.

2. Move the jog dial up/down to bring the cursor to "FILE". Then press the jog dial.

The FILE menu for selecting various operations for recorded files appears.

3. Move the jog dial up/down to bring the cursor to "MP3 ENCODE". Then press the jog dial.

The MP3 ENCODE screen for selecting the source WAV file appears.

4. Move the jog dial up/down to select the WAV file to convert. Then press the jog dial.

A screen for specifying the bit rate (amount of information per second of the MP3 file) and the file name appears.

5. To change the bit rate setting, move the jog dial up/down to bring the cursor to "BIT". Then press the jog dial.

The bit rate setting can now be changed. Move the jog dial up/down to select one of the following settings, and then press the jog dial.

- Available bit rate settings

48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps), VBR

The higher the bit rate setting, the better the sound quality. The setting "VBR" stands for "Variable Bit Rate". With this setting, the bit rate adapts to the amount of information that is to be

encoded. This method makes it possible to achieve fairly small file sizes without excessive degradation of sound quality.

6. To change the file name, move the jog dial up/down to bring the cursor to "NAME". Then press the jog dial.

The cursor disappears and a character is underlined. This indicates that the character can be changed.

Specify the name, using the same procedure as described on page 47 of the H4 Operation Manual.

7. To carry out the MP3 file conversion, move the jog dial up/down to bring the cursor to "OK". Then press the jog dial.

The conversion process starts and the indication "Please Wait" appears. When the conversion is finished, the indication "Complete!" is shown, and the file selection screen of step 3 appears again.

NOTE

If a file with the same name already exists in the current project folder, the message "This file name already exists" appears. In this case, pressing the jog dial will cause the indication of step 6 to appear again. Change the file name and repeat the procedure.

8. To return to the stereo mode top screen, press the center of the [MENU] key repeatedly.

Using the auto recording function (stereo mode only)

The auto record function makes it possible to have the H4 start and stop recording automatically, according to the input signal level. When the level exceeds a certain threshold, recording starts, and when it remains below the threshold for a given length of time, recording stops. This is convenient to record only spoken comments at a meeting or interview or similar.

To use the auto recording function, proceed as follows.

1. At the stereo mode top screen, press the center of the [MENU] key.

The main menu which gives access to various H4 settings appears.

2. Move the jog dial up/down to bring the cursor to "AUTO RECORDING". Then press the jog dial.

The AUTO RECORDING screen for making settings for the function appears.

Settings available from this screen are as follows.

START

Turns the auto record function on.

- START LV (Start level)

Sets the threshold level for automatically starting to record.

STOP LVL (Stop level)

Sets the threshold level for automatically stopping to record.

- AUTO STP

Controls the auto stop on/off setting and the number of seconds until actual recording stops. When the signal drops below the specified stop level, recording will stop after the number of seconds set here.

3. To set the start level, move the jog dial up/down to bring the cursor to "START LV". Then press the jog dial.

A screen with an input signal level meter appears on the display. The currently selected start level is indicated with a symbol.

While this screen is shown, the input signal can be monitored via the [LINE OUTPUT]/[PHONES] jacks.

While watching the input signal level on the display, move the jog dial up/down to set the start level to a suitable point. When the setting is complete, press the jog dial. The AUTO RECORDING screen appears again.

The AUTO STP setting can now be changed. Move the jog dial up/down to select one of the following settings. Then press the jog dial. The AUTO RECORDING screen appears again.

0FF	Auto stop function is disabled (Recording must be stopped manually.)
0sec	Recording stops immediately when input signal level falls below stop level.
1 – 5sec	Recording stops after 1 – 5 seconds when input signal level falls below stop level.

6. To enable the auto recording function, move the jog dial up/down to bring the cursor to "START". Then press the jog dial.

The input signal level meter appears on the display, and the indication "Wait For Signal..." is shown. This means that the H4 is in the auto recording standby condition.

In this condition, recording will start when the input signal exceeds the start level, and the name of the file will appear on the display.

NOTE

While this screen is shown, all controls except for the [REC] key and [MENU] key are disabled.

If the auto stop function is enabled, recording will stop automatically after the signal below the stop level, either immediately or after the selected number of seconds have elapsed. The H4 then returns to the auto recording standby condition and the indication "Wait For Signal..." is shown again.

HINT

• Even when the auto record/auto stop functions are on, recording will start immediately if you press the [REC] key while the first screen of step 7 is shown. If you press the [REC] key once more during recording, recording will stop immediately.

• If the signal again exceeds the start level while the H4 is in the auto recording standby condition, a new file will be opened and recording starts again.

• To return to the stereo mode top screen, press the center of the [MENU] key repeatedly.

Dividing a file (stereo mode only)

In stereo mode, the H4 version 2.0 can split an existing file into two parts at any specified point. If you have recorded a live performance, this lets you create separate files for each song.

NOTE

Depending on the type of card and the recording format, the dividing process may take about as long as the recording time of the source file. The unit should therefore be powered from the AC adapter during the process. Sufficient free space will also be needed on the card.

1. At the stereo mode top screen, press the center of the [MENU] key.

The main menu which gives access to various H4 settings appears.

2. Move the jog dial up/down to bring the cursor to "FILE". Then press the jog dial.

The FILE menu for selecting various operations for recorded files appears.

3. Move the jog dial up/down to bring the cursor to "DIVIDE". Then press the jog dial.

The screen for selecting the file to divide appears.

4. Move the jog dial up/down to bring the cursor to the source file. Then press the jog dial.

The screen for specifying the division point appears. In the lower part of the screen, a scissors icon indicates the approximate currently selected division point.

5. Use the [MENU] key to move the division point.

While the above screen is shown, you can use the [MENU] key to move the division point (current position), as follows.

Top (II) of [MENU] key

Start/stop playback

- Left part (▲) of [MENU] key

Shift position by 1 second towards beginning of file

Right part () of [MENU] key

Shift position by 1 second towards end of file

HINT

Alternatively, you can move the jog dial up/down as at the top screen to bring the cursor to the desired digit, and locate the position numerically.

6. When you have reached the intended file division point, move the jog dial up/down to bring the cursor to "OK". Then press the jog dial.

The message "Are You Sure?" appears for confirmation.

7. Move the jog dial up/down to bring the cursor to "DIVIDE". Then press the jog dial.

The division process starts and the indication "Please Wait" appears. When the division is finished, the indication "Complete!" is shown, and the file selection screen of step 3 appears again.

Two new files will be created in the stereo mode folder, with "A" (file containing data up to division point) and "B" (file containing data after division point) appended to the original file name.

If a file with the same name as would be created by the above procedure already exists in the folder, a file name change confirmation screen appears. Move the cursor to "OK" and press the jog dial to change the file name, or move the cursor to "CANCEL" and press the jog dial to cancel the file division process.

HINT

If you move the cursor to "CANCEL" and press the jog dial in step 6 or 7, the operation is canceled and the screen of the preceding step appears again.

8. To return to the stereo mode top screen, press the center of the [MENU] key repeatedly.

Raising the overall file level (normalize function)

Normalizing refers to an operation whereby the overall volume level of a file is raised so that the maximum level is 0 dB (maximum level possible without distortion). This is useful if you have finished a recording but find that the volume level is low.

NOTE

Depending on the type of card and the recording format, the normalizing process may take about as long as the recording time of the source file. The unit should therefore be powered from the AC adapter during the process.

1. At the stereo mode top screen, press the center of the [MENU] key.

The main menu which gives access to various H4 settings appears.

2. Move the jog dial up/down to bring the cursor to "FILE". Then press the jog dial.

The FILE menu for selecting various operations for recorded files appears.

3. Move the jog dial up/down to bring the cursor to "NORMALIZE". Then press the jog dial.

"Please Wait" is shown. When the operation is finished, the indication "Complete!" is shown, and the file selection screen of step 3 appears again.

HINT

If you move the cursor to "CANCEL" instead of "NORMALIZE" and press the jog dial, the operation is canceled and the screen of the preceding step appears again.

8. To return to the stereo mode top screen, press the center of the [MENU] key repeatedly.

NOTE

Normalizing can only be performed for WAV files.

Cutting the input signal off in USB audio interface mode

When using the H4 as a USB audio interface, the input signal can now be cut off.

To do this, first have the H4 recognized by the computer as an audio interface. (For details, see pages 80 - 81 of the H4 Operation Manual.) Next, move the jog dial up/down to bring the cursor to "INPUT". Then press the jog dial.

In this condition, you can select the input signal type. Move the jog dial up/down to bring the cursor to "OFF". Then press the jog dial.

NOTE

While "INPUT" is set to "OFF", the "LEVEL" and "TUNER" setup screens cannot be selected. To use these functions, set "INPUT" to a position other than "OFF" first.

Backwards compatibility of 4-track mode projects

4-track mode projects created with the H4 Version 2.0 or later will not be recognized properly by a H4 Version 1.40 or earlier.

To solve this problem, copy the project folders (PROJxxx) temporarily to a computer. Then delete the folders from the SD card. Finally, copy the folders from the computer back to the SD card.
