The ASK-4 #601 Audio Monitoring Kit from Louroe Electronics is a single-zone audio monitoring system with a wall mounted mute switch. This system is designed to interface with a DVR, VCR, or other recording devices that accept line level input. It consists of a Verifact A Microphone, a MS-1 Mute Switch, an APR-1 Audio Base Station, an AD-1 Plug-in Switching AC Adapter, and a Dual RCA Cable for connecting to a DVR / VCR or other audio devices that accept line level input (0 dB @ 600Ω). It is suitable for use in convenience stores, police interview rooms, booking rooms, fast food restaurants, casino soft count rooms, speech therapy labs, or anyplace where CCTV cameras are installed.
The APR-1 Audio Base Station is a single-zone, non-alarming audio monitoring base station. As a system (with a Louroe microphone), it provides one-way live audio with a built-in 3" (7.62cm) speaker. It features input / output jacks for connecting to a DVR / VCR that accept line level input for audio recording and playback. Other features include adjustable volume control and a 3.5mm headphone jack. A mute switch is also provided to mute the audio heard on the speaker of the headset. The distance between the APR-1 and the microphone can be up to 1,000' (305m).
The Verifact A Microphone is an omni-directional, low-impedance, electret condenser microphone with a built-in preamp for producing line level output. 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 MS-1 Mute Switch is an accessory to Louroe Audio Monitoring / Audio Surveillance systems when microphone muting is required. It contains a built-in rocker switch mounted to a single-gang stainless steel face plate. When the top part of the rocker switch is pressed IN, the rocker switch illuminates with a red light to indicate that the microphone is live and active. When the lower part of the switch is pressed IN, illumination of the switch turns OFF, indicating that power to the microphone is cut off and the microphone is disabled. The MS-1 Mute Switch fits into a single-gang backbox (sold separately) for mounting to a wall or flat surface.
The UL listed AC adapter supplies 12VDC to the base station and microphone.
