The ASK-4 #304-DV Audio Monitoring Kit from Louroe Electronics is a 4-zone audio monitoring system designed for making a direct connection to a DVR, PC soundcard or IP Network Camera. This kit consists of 4 Verifact D-V Microphones, 4 Single RCA cables for connecting to a DVR / VCR, an IF-4 Audio Interface Adapter, an AD-1 Plug-in Switching AC Adapter, and 4 RCA to 3.5 Mono Adapters for connecting to an IP Camera with a 3.5mm mono audio input.
The Verifact D-V Microphone is a low impedance, electret condenser microphone mounted to a 16 gauge stainless steel faceplate. It fits into a single gang electrical box for flush or surface mounting and is designed for areas of high vandalism. It is suitable for use in convenience stores, warehouses, booking rooms, interrogation rooms, hospital observation rooms, parking structures, casino soft count rooms, or where CCTV cameras are installed.
The Louroe IF-4 Audio Interface Adapter is designed for connecting up to 4 Louroe microphones to a DVR or other recording devices that have multiple audio inputs. The units contain RCA outputs (per microphone) for accommodating either an RCA input or a 3.5mm (mini jack) input connection to a DVR, an IP network camera, or a video server using the connector cables supplied. The IF-4 audio interface adapter provides phantom power to the Louroe microphones, and it contains a variable gain adjust per output to prevent the overdriving of the DVR.
The function of the Audio Test Switch is to indicate the presence of audio and to assure that the IF-4 Audio Interface Adapter is driving the audio signals into the input of the audio receiving device. The audio indicator LED illuminates when audio is present.
Note: Wiring Requirements: 2 conductor shielded cable, 22 gauge with a 24 gauge drain wire. Unshielded cables are not suitable for audio systems. When this equipment is used as part of an audio monitoring system, the law requires that the public be given notice of AUDIO MONITORING ON THE PREMISES. A decal notice is included with each microphone shipped.
