72 GB voice recorder for lectures

The Xelarvex REC-1120 stores up to 4800 hours of WAV audio at 192 Kbps on its 72 GB internal memory. Voice-activated recording begins only when sound is detected, removing silent gaps and extending usable capacity. It connects via USB-C for file transfer and charges fully in 1.5 hours.

Sustained recording with AI noise reduction

The lithium-ion battery delivers 48 hours of continuous recording on a full charge, with each session limited to 2-hour auto-saved files. An AI sound-processing chip reduces 97 % of ambient noise during long sessions, keeping clarity consistent without manual gain adjustments. Low-battery protection secures every file before shutdown.

Replaces smaller recorders and phone apps

The jump is worthwhile when 72 GB of local storage and 48-hour battery life remove the need for frequent offloading or cloud reliance. Buyers who need real-time streaming, multi-track capture, or expandable media slots will not find those functions here. The 0.132 kg body clips to a lanyard or bag for hands-free use.

Questions about this item

Does the 72 GB recorder get warm or make noise during a full 48-hour session?

The unit weighs only .132 kg and has no moving parts, so it runs silently and stays cool even after 48 hours of continuous recording.

What cable or adapter must I already have to move WAV files off the USB-C port?

You need a USB-C cable — either USB-C to USB-C or USB-C to USB-A — to connect the recorder to your computer for file transfer.

Will the 3.5 mm headphone jack work with my older wired headset without an adapter?

Yes, the built-in 3.5 mm connector accepts any standard 3.5 mm headphone plug directly.
