Description
VBF-4: 4 Channel Voice Band Notch Filter and DVR Interface Box
The VBF-4 is a versatile and cost-effective solution for background noise reduction and improved speech intelligibility. Designed for use with ETS microphones and DVRs, this four-channel module provides a boost of frequencies in the human voice band (1.7kHz) and 10dB per octave attenuation on both sides of the bandpass.
Enhanced Speech Clarity
With the VBF-4, you can significantly reduce background noise, allowing for clearer and more intelligible speech. By boosting the frequencies in the human voice band and attenuating unwanted noise, this device ensures that important audio information is not lost in a sea of distractions.
Flexible Options and Easy Installation
The VBF-4 interface box is designed to be conveniently located next to a DVR or IP camera. It requires a 120VAC power source within 3 feet of its location. However, if this is not feasible in your application, you have the option to splice in up to 100 feet of 22 AWG, 2 conductor cable to extend the distance between the AC power source and the vbf-4. Additionally, for added convenience, you can choose to add a -3.5mm or -FL (flying leads) output cable to the vbf-4 by specifying the appropriate part number. Experience improved audio quality and enhanced speech intelligibility with the VBF-4 four Channel Voice Band Notch Filter and DVR Interface Box. Invest in this low-cost solution today and enjoy clearer communication in your audio recordings and surveillance systems.
