Additional Descriptions

MP3 (MPEG AUDIO LAYER-3)

MP3 is a music file format that can contain music with stereo sound quality as good as an audio CD. Compression rate is 1MB/1 minute, thus about 3-5MB for a typical 3-5 minute song. Different from an audio CD, a CD comprised of MP3s can contain over 130 songs, and playing time would be about 6 to 10 hours. The MP3 format removes high frequencies which human ears cannot hear, so it has the advantage of being able to compress the a file to 1/12 or so while maintaining sound quality equivalent to an audio CD. The size of a typical audio CD is roughly 50MB. If the same tracks are compressed to MP3s, it then becomes about 4-5

MB.

- WMA (WINDOWS MEDIA AUDIO)

WMA is a multimedia compression method developed by Microsoft Corporation® and is used to compress music exclusively used in “Windows Media Technologies.” It provides the same sound quality as MP3s using half the Kbps (64 Kpbs vs. 128 Kbps). In other words, it’s half the file size of an MP3 with the same sound quality.

Operation

1. Make sure that speakers and input/output cables are properly connected before you plug in the power.

2. Set all volumes to the minimum position before you turn the power on.

3. Be sure the AC power is the correct voltage before you plug in the power cord.

4. Ensure that the VFD displays and the unit functions when the power button is pressed.

5. Adjust the volume for each channel, as well as the master volume.

6. Adjust the mic channel EQ.

7. Please refer to the CD / FM operation method or Set Up mode section for details.
