Capture every meeting in excellent, noise-free audio quality. Simply place the 360? meeting microphone on the table and press record to capture all speakers, from every angle. Capture and store up to 88 days of continuous recording thanks to the 8 GB of internal memory. A micro SD memory card slot for up to 32 GB of additional memory guarantees virtually unlimited recording capacity. The high-capacity Li-ion polymer battery can be easily charged through a standard USB C jack. This guarantees extended battery life for extra-long recording up to 36 hours, ensuring that your recorder will always be ready to work when you are. Control your audio recorder using your smartphone, even from a distance. The Philips Voice Tracer app makes recording events such as lectures much easier and more convenient. You can place your recorder in the front of the room near the speaker, take a seat at the back, and still control recording comfortably and without interrupting the lecture. The Philips Voice Tracer app can be downloaded for free from the Apple App Store or Google Play Store.
