Useful information

• What is Linear PCM (Pulse Code Modulation) recording?

Linear PCM (LPCM) recording is a digital recording method that samples analog audio signals at a certain frequency and saves them as digital signals without compression.

Music CDs (CD-DA–CD digital Audio) use PCM recording (sampling rate of 44.1kHz, bit depth of 16-bit samples, bit rate of 1,411kbps, and frequency response from 20 to 20,000Hz). PCM recordings are digitally-recorded unprocessed audio, and are supposed to be of the highest sound quality.

“WAVE” format is used to import these PCM recording files into a computer. The WAVE file extension is “.WAV”. MP3 and WMA format files are created by compressing the LPCM data.

• What is recording margin?

Recording margin is the space (margin) expressed in dB between 0dB and the most recent maximum input volume.

The unit will not display all the following indicators and items at the same time.

For information on recording preparation, please refer to the Owner’s Manual.

Recording a musical performance

Before recording, make sure that the recorder displays the recording level (that is, the ALC function is turned off) (page 13). Also, set [MICSENS] (microphone sensitivity) to [LOW] (page 13).

1. Point the built-in stereo microphone

toward the sound source, then press the [REC] button.

The unit enters recording [STANDBY] mode. The LED indicator flashes red slowly.

(Recording has not started yet.)

The level meter will move left or right in response to the sound level from the microphone.

2. Press the [INPUT/SPEED] (+/–) buttons located on the side panel to adjust the

INPUT level (recording level).

Adjust the recording level while playing music toward the microphone.

Setting the recording peak limiter

When the recording peak limiter is set to ON, the recorder reduces sound distortion by automatically adjusting excessive peaks. It is recommended that you set the limiter to ON when you record audio (page 17). However, if you want to adjust the recording level (see below), set the limiter to OFF.

■ Adjusting the recording level

You can adjust the recording level in the range of 0 through 40. When the recording level is set to “0,” silence will be recorded.

• Setting an appropriate recording level

Adjust the recording level so that at the loudest source volume the level meter will move as far to the right as possible without deflecting all the way (and so that the recording LED will NOT flash rapidly during recording).

POCKETRAK C24 Reference Manual

• If the recording level is too low:

Press the [INPUT/SPEED](+) button to adjust the recording level so that the level meter will move moderately to the right.

If an appropriate recording level cannot be achieved even if you raise the level to “40,” set [MIC SENS] to [HIGH] (page 13).
