Linear PCM and MP3 Recording Times

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).

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.
