MICRO BR: Digital Recorder<\/strong><\/p>\n

Tracks<\/B>
Track: 4
V-Track: 32 (8 V-Tracks per each Track)
* Up to 2 tracks can be recorded simultaneously, and up to 4 tracks can be played back simultaneously.
\u25cfUseful Capacity<\/B>
SD memory card: 32mb \u0096 1G bytes
\u25cfData Type<\/B>
HiFi (MT2)
STANDARD (LV1)
LONG (LV2)
\u25cfAudio Data Type (MP3 Mode)<\/B>
MP3 (192 kbps, 44.1 kHz)
MP3 (128 kbps, 44.1 kHz)
MP3 (64 kbps, 44.1 kHz)
WAV (44.1 kHz, 16 bit)
* The MICRO BR can play the MP3 in bit rate range of 64 kbps\u0096320 kbps.
\u25cfSignal Processing<\/B>
AD Conversion:
24 bit+AF method (GUITAR IN, onboard mic)
24 bit (LINE IN\/MIC)
DA Conversion: 24 bit
* AF method (Adaptive Focus method)
Adaptive Focus is a unique Roland\/BOSS technology that allows the signal noise (S\/N) ratios of AD and DA converters to be vastly improved.
\u25cfSample Rate<\/B>
44.1 kHz
\u25cfFrequency Response<\/B>
20 Hz to 20 kHz
\u25cfRecording Time (conversion in one track)<\/B>
* The listed recording times are approximate. Times may be slightly shorter depending on the number of songs that were created.
* The number is the total for all the tracks that are used. If each of the four tracks contain an equal amount of data, the length of the resulting song will be approximately 1\/4 of the above.
* The memory capacity (recording time) decreases when the MP3 file etc. exist in the memory.
