Tentacle Sync TRACK E - pocket audio recorder

Easy integration into your workflow.
One app. Countless possibilities.

Our Tentacle Setup App – which remotely controls everything except the weather – helps you enjoy seamless integration into your current workflow. Setup, control and monitor your TRACK E's audio via Bluetooth® on your mobile device. One screen. All the information you need.

Everything you need to get started. Straight out of the box.

Unbox your TRACK E and you can be ready to go in just three minutes. Here’s what you get: One pocked-sized TRACK E audio recorder, a multi-purpose lavalier microphone and a 16GB microSD card. The lockable mic input is compatible with any lavalier mic, that you might already call your own. Monitor and playback your recordings via headphone out, charge your unit and transmit your data through the USB-C port really fast. It even comes with a funky black belt clip to free up your hands while recording.

32-bit floating-point technology.
Hit record and start creating.

Say goodbye to leveling and digital clipping. The TRACK E with its significantly enhanced dynamic range is a versatile, set-&-forget device that always delivers high quality audio. Users can treat audio like photographers use the RAW camera photo format. You don’t need to worry about the gain of the recorded audio. All details can simply be adjusted in post-production, significantly reducing pre-shoot preparation time. Recorded too low? Simply raise the volume without raising the noise floor.

100% lavalier microphone compatibility. Just clip and go.

The TRACK E comes packed with its very own broadcast-ready lavalier microphone. Yet, if you still prefer to use your own mics, you can – we also offer a range of suitable adapters to give you the flexibility you’re looking for. The microphone plugin power is 5 volts, so even more microphones are compatible.
