• Frequency Response: 500Hz ~13Khz
• Cut-Filters: Hi-Cut/Low-Cut to Reduce Background Noise (900~6Khz)
• Amplifier: Low Noise MOSFET
• Audio Output: Jumper Selectable for Line-Level (0db) or Microphone Output (30dB)
• Peak Limiter: 5 Sec Response Time
• Output: 100 Ohm unbalanced output
• Operating Temp: -40ºC to +105ºC

Disguised as a typical smoke detector, the unit features a built-in limiter circuit which automatically lowers the output level during loud sound intervals. Selectable cut-filters also limit background noise. Suitable for ceiling mount, one can connect the unit to the E-AUD-SMEA-1HP accessory when implementing an IP PoE powered surveillance system.
