Yamaha POCKETRAK 2G Brochure & Specs page 5

Only 1.7 Ounces and 1/2 Inch Thick
—Take it Everywhere!
The POCKETRAK 2G is so light and compact that there's
no reason not to take it with you wherever you go. In addition
to recording rehearsals and lessons for later review and study,
you'll always be prepared to capture the sounds of nature or the city,
samples for audio production, meetings, lectures, and much more.
2 GB Memory for High Audio Quality
and Extended Recording Times
The POCKETRAK 2G features a capacious 2 gigabytes of memory built in so that it can
deliver outstanding sound quality as well as extended recording times as required.
When you want maximum sonic quality in stereo you can record using the linear PCM
mode for up to 3 hours and 10 minutes with full CD quality (44.1 kHz, 16 bits).
Linear PCM and MP3 Recording Times
Record Mode Frequency (Hz)
Linear PCM 40~20000
XHQ 40~15000
MP3 HQ 40~7500
SP 40~3500
Note: Due to the characteristics of the internal memory, recording times may be slightly shorter in some cases.
High-sensitivity Tilt-up Microphone
In addition to superior basic performance, the built-in
stereo microphone can be tilted upward when the
POCKETRAK 2G is placed on a desk or table to minimize
sound degradation due to reflection
from the surface as well as pickup
of mechanically transmitted noise.
This high-performance microphone
delivers excellent sound quality and
signal-to-noise performance in a
variety of recording situations.
Level Meters and ALC for Optimum Record levels
For maximum quality when recording music you'll want to set the
record level manually. In manual mode the record level can be adjusted
in 31 steps (0-30), and the POCKETRAK 2G has level meters and a peak
indicator that make setting optimum levels quick and easy. For speech
you can let the POCKETRAK 2G set the record level for you automatically
by simply switching the ALC (Automatic Level Control) function ON.
When ALC is ON the POCKETRAK 2G will automatically maintain the
best recording level for maximum clarity and intelligibility.
