5 Highlights
• -10 dB Pad
Attenuates the microphone input to allow for the recording of loud sounds
without clipping.
• 75 Hz/150 Hz High Pass Filter
Reduces low frequency and infrasonic rumble from HVAC systems indoors or
street traffic outdoors from over-powering the recording.
• High Frequency Boost
Restores some of the high frequency content that is often lost when a blimp or
furry windshield is placed over the microphone and improves the intelligibility of
recorded speech.
• Rechargeable built-in Li-ion battery
The built-in battery supports at least 150 hours operation.
