Features and Construction
The recorder is designed for straightforward use in professional and personal settings. Each feature is selected to improve ease of use and reliability during recording sessions.
Material and Build
The shell is made from metal and zinc alloy, offering resistance to drops during everyday handling. The unit measures 70 by 23 by 8 mm, allowing it to attach easily to a keyring. Black and silver colour options are available.
Recording and Playback
The ATJ3315D chip records in WAV format at 192 kbps and a sampling rate of 48 KHz. Voice control induction recording starts automatically when ambient sound crosses a preset threshold. The AGC function adjusts sensitivity to reduce background noise. Playback supports WMA, WAV, MP3, and OGG formats via headphones plugged into the USB jack.
Storage and Battery
Available in 32GB or 64GB versions, the recorder saves up to 188 hours or 376 hours of recording time respectively. The built-in 150 mAh rechargeable lithium battery provides about 15 hours of recording or 10 hours of playback. Charging takes approximately 2 hours.
Uses and Placement
The keychain form factor means the recorder is always accessible for spontaneous recording needs. It suits environments where quick, hands-free capture is valuable.
Meetings and Lectures
Place the recorder on a table or clip it to a lapel to capture lectures, meetings, or presentations. Voice activation conserves storage by recording only when speech is present.
Interviews and Research
Journalists and researchers can use the device to record interviews without needing to operate a main recording device. Password protection keeps sensitive files secure.
Everyday Reminders
Use the one-key record/save button to capture quick voice notes, reminders, or shopping lists. The timestamp feature automatically names each file by date, simplifying later retrieval.
Benefits and Buying Value
The recorder offers multiple functions in a single device, reducing the need for separate tools. Long battery life and automatic features make it convenient for regular use.
Reuse and Low Maintenance
The rechargeable battery eliminates the need for disposable cells. The USB 2.0 interface allows easy file transfer to any computer running Windows 2000 or later. Auto-save on low battery prevents data loss.
Why Choose This Product
The metal and zinc alloy construction provides drop resistance that plastic-only recorders may lack. Password protection adds a layer of security for private recordings.
