DESCRIPTION
Louroe Model IF-2, IF-4 and IF-8 are audio interface
adapters designed for connecting up to two (IF-2),
four (IF-4) or eight (IF-8) 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, IP network camera, video server,
etc. using the connector cables supplied. In addition, the IF-
2, IF-4 and IF-8 receive wiring from the Louroe
microphones, provide power and contain a variable gain
adjust per output to prevent the overdriving of the DVR, etc.
All Louroe microphones are compatible with these three
units.
AUDIO TEST SWITCH
It’s function is to indicate the presence of audio and to
assure that the IF-2/IF-4/IF-8 is driving the audio signals
into the input of the audio receiving device. The audio
indicator LED illuminates when audio is present.
Between Louroe Microphone and IF-2/IF-4/IF-8:
2 Conductor shielded cable, 22 gauge with a 24
gauge drain wire.
