The TRACK E Timecode Audio Recorder can easily fit in your pocket for recording on the go. This allows mobile operation for example as a recorder for a clip-on microphone eliminating the need for a radio-link. This means that the TRACK E will work in environments where regular wireless transmitter fail. 

Controllable through the Setup App for iOS or Android, it seamless integrates into the Tentacle Sync eco system. The app lets you synchronize timecode and operate as many Tentacle devices as you need via Bluetooth. You can monitor audio wirelessly and will be notified immediately by the app if something doesn’t go as planned. For even more convenience, you can sync, start and stop your TRACK E devices from your Apple Watch.

TRACK E features 32-bit floating point technology for a significantly extended dynamic range. 32-bit floating point also means that no digital clipping will occur, making the TRACK E a versatile set-&-forget-device that will always deliver high quality audio. With the TRACK E users can treat audio in a similar way as photographers use the RAW camera photo format – all details can be adjusted in post production, significantly reducing the preparation time before you start shooting. In addition, regular 24-bit recording is supported as well.

The TRACK E uses its included 16 GB microSD card for recording. An input limiter and a high-pass filter guarantee for pristine recording quality. A 3.5 mm locking connector offers a secure connection for your microphone. In addition to wireless sync, TRACK E features standard SMPTE timecode input/output so you can also connect to other timecode devices. A free license of Tentacle Sync Studio (Mac) is included with every TRACK E purchase.
