The ASK-4 #200 Audio Monitoring Kit from Louroe Electronics is a single-zone audio monitoring system designed for making a direct connection to a CCTV monitor with a built-in amplifier and speaker. This kit consists of a Verifact A Microphone, a MA-1 Interface Adapter, a Single RCA Cable, an AD-1 Plug-in Switching AC Adapter, and a Dual RCA Cable for connecting to a DVR / VCR. It is suitable for use in convenience stores, fast food restaurants, booking rooms, interrogation rooms, day care centers, sleep disorder centers, therapy labs, cashier booths, gas stations, or anyplace where CCTV cameras are installed.
The Verifact A Microphone is an omni-directional, low impedance, electret condenser Microphone with a built-in preamp for producing line level audio. It is housed in a high impact ABS dome designed for ceiling or wall mounting. The normal pick-up pattern is approximately 15' (4.57m) from the microphone location towards all directions, or within a 30' (9.14m) diameter circle.
The MA-1 Audio Interface Adapter is designed for connecting a Louroe microphone directly to a CCTV monitor with a built-in audio amplifier. It contains a terminal block for receiving the microphone signals and amplifies it for input to the CCTV monitor. It also supplies 12VDC phantom power to the microphone. The MA-1 Audio Interface Adapter also has RCA audio out in jacks for audio recording and playback. Audio playback is done through the CCTV monitor.
The Dual RCA Cable allows connection to DVRs / VCRs or other audio devices that accept line level input. The UL listed AD-1 Plug-In Switching AC Adapter supplies 12VDC to the IF-2 Interface Adapter and Verifact A Microphone.
