ETS SM5-EQ-PSSE-LN SMEQ-1 Seven band Equalizer DVR interface, SM1-PSSE Low noise Microphone

The SM5-EQ-PSSE-LN from ETS is a single zone audio surveillance system designed for DVRs and I/P cameras, ideal for acoustically challenging environments. Its seven-band equalizer allows +/-12db sound emphasis or de-emphasis across frequencies from 60hz to 15khz, enabling users to minimize background noise while emphasizing target sound sources. The included SM1-P ultra low noise microphone further enhances performance with adjustable automatic gain control, making this kit perfect for police booking and interrogation settings.
