Manual

INSTALLATION TIP: If area to be monitored for audio is noisy or has background disturbances, the
microphone should be positioned close to the subject as possible. Also, the microphone sensitivity
switch can be moved from “N” position to “L” position to help reduce background noise.
“N” is normal,” L” is low.
Verifact B connects directly to any Louroe Base Station or Louroe Audio Interface Adapter(IF-1, IF-2, IF-4
or IF-8). The Base Station or Interface Adapter provides phantom 12Vdc power to the Verifact B
Microphone.

Black wire (audio out) to terminal B 2. connects of microphone terminal block
3. Bare wire (ground) connects to terminal C of microphone terminal block
NOTE: If using wiring with a different color code, be sure they are properly matched
between the microphone and Louroe Base Station or Interface Adapter.
A represents +12 Vdc power
B represents Audio Output
C represents Ground
A 3-pin terminal block is located on the back of the microphone housing, marked A, B, C.
CONNECTING VERIFACT B MICROPHONE TO A LOUROE BASE STATION OR AUDIO
INTERFACE ADAPTER
All Louroe audio base stations (except the ALA-4/8 series) and Interface Adpaters have corresponding
terminal blocks marked A, B, C. Connect other end of cable as follows:
1. Red wire from microphone connects to pin A of Base Station or Interface Adapter (12Vdc)
If base station is ALA-4/8 series, please refer to installation instructions for the specific model.
2. Black wire from microphone connects to pin B of Base Station (Audio Output)

CONNECTING VERIFACT B MICROPHONE TO OTHER AUDIO DEVICES.
If a Louroe audio base station is not used and microphone is being connected directly to another source
from other manufacturers, 12 Vdc power must be applied to terminals A and C. (A is positive, C is
negative). Terminals B and C of microphone (C is common) go to the “Audio In” or “Line in” of the audio
source. Wire from terminal B should be shielded.
