The APR-1 Desktop Audio Base Station is a single-zone, non-alarming audio monitoring base station. As a system (with a Louroe microphone), it provides 1-way live audio with a built-in 3" (7.62cm) speaker. It contains 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 RN-2 Audio Mixer is used for combining 2 Louroe microphones or speaker / microphones for the purpose of expanding the area to be audio monitored. It has an input side (terminal block) for accepting 2 microphones and an output side (terminal block) for home running back to a Louroe Audio Base Station or to other audio receiving devices. The RN-2 Audio Mixer contains a potentiometer for microphone balance control. The RN-2 Audio Mixer receives phantom power from the Louroe Base Station.
