For sensitive situations such as legal hearings, investigations, news gathering, and team meetings, the Marantz PMD-661 MKIII portable handheld recorder is designed to securely capture two tracks of high-resolution audio with password-protected file encryption. Use the onboard stereo condenser mic array or connect the included omnidirectional boundary microphone to record clear, intelligible speech without having to transport external mics, cables, and stands.
Run the PMD-661 MKIII for up to seven hours via four AA batteries or power it for extended events using an AC adapter. Multiple inputs including 3.5mm, XLR-1/4″, and coaxial digital jacks allow you to record analog mic- or line-level signals or a stereo digital source. High- and low-pass filtering, manual or automatic level control, and a selectable mono safety track mode empower you with the tools you need to realize clear recordings free of distortion.
Power the PMD-661 MKIII for up to seven hours of stereo recording time at 16-bit / 44.1 kHz resolution via four AA alkaline or NiMH batteries. The switchable beep alarm alerts you when the battery power is low, and battery life can be conserved by setting the automatic power-off function to turn off the PMD-661 MKIII after 5, 15, 30, or 60 minutes. Also, the display can be switched off automatically after 30, 60, or 90 seconds without a button press.
For extended recording time, the PMD-661 MKIII may be powered through the included AC adapter. If the AC adapter plug is inserted while using the recorder on battery power, the recorder will automatically switch to adapter power. Upon removing the AC adapter plug, the recorder will automatically switch to battery power.
The PMD-661 MKIII offers several recording functions that simplify your workflow. Enable the pre-record function to put the PMD-661 MKIII in record pause mode, which continuously buffers two seconds of audio. Once the record button is pressed, the PMD-661 MKIII writes the buffered audio to your media card and continues recording.
Turn on Silent Skip to automatically pause the recording during periods of silence and resume recording when the silence ends. The threshold that defines silence may be set to -60, -54, -38, or -20 dB.
