Voice recorder with 16 GB storage

The Shenzhen Gosun GX-20 is a compact digital voice recorder offering 16 GB of internal memory for capturing meetings, lectures or personal notes. It records in WAV format and doubles as an MP3 player for playback through the built-in 20 mm speaker or supplied earphones. A rechargeable lithium battery powers the unit.

250 hours recording time and VOR

Four selectable modes — SP, LP, SP VOICE and LP VOICE — let users balance quality against capacity, with a maximum bit rate of 384 KBPS. Voice-operated recording starts automatically when sound is detected and pauses during silence, extending the effective 250-hour runtime. The battery delivers up to 20 hours of continuous use per charge.

USB 2.0 interface and telephone adapter

A standard USB connection provides driver-free file transfer to a PC and charges the battery. An included telephone adapter enables recording of landline conversations by connecting the recorder between the handset and base. The package also supplies an external microphone and audio cable for additional input options.

Questions about this item

Can I plug the GX-20 straight into my older Windows 7 laptop via USB without installing a driver?

How do I confirm the VOR voice-activated mode is actually triggering on sound?

Set VOR to ON, press REC; the red LED flashes when recording starts and pauses when silence returns.

Does the package include everything needed for telephone recording or must I buy an adapter separately?
