The AP-4 Audio Base Station is a non-alarming audio monitoring base station that provides 4 audio zones. The AP-4 Audio Base Station accommodates 4 Louroe microphones and has 4 line level audio outputs. It contains a 3” (7.62cm) built-in speaker for producing live audio and audio playback from a DVR. In addition, it also contains a selectable RCA audio output for interfacing with a DVR with only one audio input, or with a VCR. You can select a zone by using the pushbutton.
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 up to 15' (4.57m) from the microphone location towards all directions, or within a 30' (9.14m) diameter circle.
