POCKETRAK C24 Owner’s Manual

Introduction

Estimated available recording time (with internal 2GB memory)

* If you record multiple files, the total available recording time will be shorter than those estimated above.

* When you purchase the recorder, the manuals are stored in PDF format in the internal memory. Therefore, the actual

available recording time is less than estimated above.

* The largest available recording space (for continuous recording) in one file is 2GB.

■ About the ALC (Auto Level Control) function

The Auto Level Control function automatically adjusts the recording level in response to the

source level so that the resulting recording will be tighter dynamically.

■ Microphone sensitivity

You can set the microphone sensitivity level to high or low to accommodate the recording environment.

If the recorded audio level is too low or too high, change the microphone sensitivity setting.

Setting the microphone sensitivity

Press the [MENU/FOLDER] button while the main screen is displayed, select [REC MENU] → [MIC SENS], then

select [HIGH] or [LOW]. If the volume level is too low, select [HIGH]. If the volume level is too high, set [MIC

SENS] to [LOW].

■ Recording peak limiter

When the recording peak limiter is set to ON, the recorder reduces sound distortion by automatically adjust-

ing excessive peaks. It is recommended that you set the limiter to ON when you record audio.

Setting the recording peak limiter

Press the [MENU/FOLDER] button while the main screen is displayed, select [REC MENU] → [REC LIMITER],

then select [ON]. The peak limiter is available only when the ALC function is set to OFF.

Feature

The recording will accurately rep-

resent the original sound, and

maintain sound dynamics as is.

The recording dynamics will be adjusted. Louder sounds

will be quieter and softer sounds will be louder. This setting

will reduce distortion and is better for recording dictation.
