Audio Monitoring kits multi-function audio monitor head

-Integrating with video surveillance or set up seperatelly! This multi-function audio monitor head is the production of highly sensitive monitoring products.using advanced integrated circuit from U.S.A, with high sensitivity, super-mute function of monitoring an area of about 100 square meters.It makes use of the most advanced circuit design, super-mute, anti- Scream features, built-in automatic gain AGC circuit to enhance long-distance voice, unique DSP audio output mute, so that the effect of exceptionally clear audio playback. Widely used in banks, prisons, police, justice, security checks, and other hospital departments, such as hard disk video recording environment.

1. German import program A7-audio static noise level of professional sound environment for pickup (first monitor). 
2. imports from the United States IC, with the professional circuit to deal with the pickup, clear voice, no noise.
3. import large Diaphragm Condenser Microphone, anti, anti-environmental noise, wide-angle acquisition voice, without a corner, listening area of 100 square meters.
4. built-in dynamic audio processing circuit, and other non-voice for the voice amplification for treatment, the total elimination of environmental noise.
5. built-in automatic gain AGC circuit, far from close range to eliminate the voice of the differences so that a more realistic playback.
6. semi-circular enclosure, the installation of accessible and user-friendly tone pinhole into the mouth, wide-angle sound mining, non-reflective tone.
7.shallow convex surface, anti-echo, to reduce obstacles in the acoustic more realistic, echo smaller, to achieve the ideal state.
8. high output impedance, low-transmission cable, audio output intensity, strong drive for a variety of recording equipment.
9. internal circuit-MIC, preamplifier, AGC circuit, dsp the elimination of noise (noise attenuator) circuit, power amplifier.
10. A7-audio monitoring head for the bank, police, inspection, judicial, military, and other national security department uses the voice of the acquisition.
11. transmission cable core with the use of a shield line, or the common core of the two power lines, transmission distance in accordance with the decision diameter size, as far as possible to avoid high-voltage transmission line audio cable layout.
