Menu setting method Rec Mode The recorder can record in the linear PCM format. High resolution recording at a high sampling rate and high bit rate equivalent or superior to that of a music CD is possible. Moreover, it also supports the MP3 and WMA formats. 1 Select the recording format. [PCM]: This is an uncompressed audio format which is used for music CDs and the like. [MP3]: MPEG is the international standard established by a working group of the ISO (International Organization for Standardization). [WMA]: This is an audio compression encoding method that was developed by the Microsoft Corporation in the US. 2 Select the recording rate. When [PCM] is selected: [96 kHz/24 bit] to [44.1 kHz/mono] When [MP3] is selected: [320 kbps] to [mono] When [WMA] is selected: [128 kbps] to [mono] • If the directional microphone function is used, you cannot change [PCM] setting in [Rec Mode] to one other than [44.1kHz/16 bit]. You can use the all modes in [MP3] or [WMA] of [Rec Mode]. • When [mono] of [MP3] is selected, the recording rate will be set to 64kbps. • When [mono] of [WMA] is selected, the recording rate will be set to 8kbps. • To record a meeting and lecture clearly, set [Rec Mode] to a position other than [mono]. • When the external monaural microphone is used while [Rec Mode] is set to a stereo recording mode, it enables recording only with the L channel microphone. Rec Level You can set the device to automatically or manually adjust the recording level. 1 Select [Manual] or [Auto]. [Manual]: Recording is performed by manually adjusting the recording level. [Auto]: Recording is performed by automatically adjusting the recording level. This is useful for when you will be recording right away. • If you select [Manual], proceed to the operation of step 2. Menu setting method 2 Select limiter function. [Limiter ON]: 4 This function will adjust the input level when sudden high volume is encountered. This will prevent sound distortion. [Compressor ON]: This function will adjust the level variation when high- and low-volume input signals are mixed. The input level will be generally equalized to a listenable sound. [Limit/Comp off]: Use this position when adjusting the input levels without using the correction function. Adjust the recording level: 1 Press the 9 or 0 button while the recorder is recording or paused to adjust the recording level. • Distorted sound will be recorded while [OVER] is displayed. Adjust the recording level so that [OVER] will not be displayed. If sound distortions do not disappear even after the recording level has been adjusted, change the setting for microphone sensitivity (☞ P.50) and adjust the recording level again . EN 51
