Super Sensitive Amplifies Normal Hearing up to 37 Times! Hear a conversation up to 100 Yards
Flashlight-sized electronics is interfaced with a 12" lightweight plastic parabolic reflector, providing over 30 db of pick up gain! The parabolic dish gathers sound and focuses it to an amplifier which further increases sensitivity, resulting in an impressive boost beyond normal human hearing. Includes parabolic dish with built-in handle and amplifier mount, a hi-gain microphone/amplifier, and headsets with adjustable volume for each ear. Runs on a 9v battery which lasts ~40 hours (not included). Field-use weight is 13 ounces (shipping weight is greater due to packaging).
SMAT815R - Shotgun Directional Microphones |
Intended for Long Range Nature Listening and Video Recording. The advantage of shotgun microphones is their ability to "hone in" on a sound source and reduce the amount of background noise. Many variables effect the transmission of sound at long distances -- whether the source is facing you, the air density and temperature, the amount of background noise, and of course the source volume. The ability to hear your target can be greatly effected by any one of these. |
Professional Performance Shotgun Microphone
Designed for video production and broadcast (ENG/EFP) audio acquisition, the SMAT815R provides the narrow acceptance angle desirable for long-distance sound pickup, along with excellent sound rejection from the sides and rear of mic. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.
This is for the microphone only; does not include stand or cable.
- Size: 18.5 X .83"
- Weight: 9 Oz.
- Sensitivity: 12.6mv / 10 microbars
- Power: External
- Acceptance: 40 Degrees
- Can hear normal conversations from ~100 yards away
