VERIFACT BGC
AUDIO MONITORING SYSTEM
INSTALLATION AND OPERATING INSTRUCTIONS
The Verifact BGC is an omni-directional, low
®
impedance, electret condenser microphone with built-in
preamp and automatic gain control. The microphone
element is extended 3’ for high ceiling applications. It
can pick up normal sounds approximately 25 ft. away,
or within a 50 ft. diameter circle. It’s built-in limiter
prevents the output signal to be overdriven thus
minimizing distortion. Verifact B-AGC produces line
®
level output (0 dB) and can be located up to 1,000’ from
the Louroe base station. The microphone has a
potentiometer to adjust the output gain up to +10dB. It
is primarily designed for ceiling mounting but can also
be installed on any type of flat surface. The Verifact
®
BGC is compatible with all Louroe Audio Base Stations
or Louroe Audio Interface Adapters.
NOTE:
Verifact BGC Microphone is NOT
®
recommended for outdoor use or in areas with
high moisture content.

INSTALLATION AND OPERATING INSTRUCTIONS
ELECTRICAL CONNECTION:
The Verifact BGC is cylindrical, 4” dia. x 1½” H, and has four mounting holes for surface mounting to a ceiling
or other flat surface. It should be positioned so that the microphone is 4’ to 8’ from the area of desired
coverage.
MICROPHONE CONNECTION:
A 3-pin terminal block is located on the back of the microphone housing, marked A, B, C.
If using West Penn 452 or equivalent with same color code, connect:
CONNECTING VERIFACT BGC MICROPHONE TO A LOUROE BASE STATION OR AUDIO
INTERFACE ADAPTER
All Louroe audio base stations and Interface Adapters have corresponding terminal blocks marked A, B, C.
Connect other end of cable as follows:
®
A represents +12 Vdc Power
B represents Audio Output
C represents Ground
1. Red wire (12 Vdc) connects to terminal A of microphone terminal block
2. Black wire (audio out) connects to terminal B of microphone terminal block
3. Bare wire (ground) connects to terminal C of microphone terminal block
®
1. Red wire from microphone connects to pin A of Base Station (12Vdc)
2. Black wire from microphone connects to pin B of Base Station (Audio Output)
3. Bare wire from microphone connects to pin C of Base Station (Ground)
CONNECTING VERIFACT BGC MICROPHONE TO OTHER AUDIO DEVICES.
®
If a Louroe audio base station is not used and microphone is being connected directly to another receiver 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. We
recommend shielded cable connections for terminal B and C (See last page for interconnection diagram)
INSTALLATION TIP: If area to be monitored for audio is noisy or has background disturbances, the
microphone should be positioned close to the subject (4’ - 8’) if possible. Also, the microphone output can be
lowered by adjusting the gain control potentiometer. Rotating clockwise will increase the gain;
counterclockwise decreases the gain. The factory setting is 0dB output.
INSTALLATION TIPS
1. Use 2 Cond 22AWG overall shielded audio cable only. West Penn 452, Belden 8451 or equivalent.
UNSHIELDED CABLE IS NOT SATISFACTORY FOR SOUND SYSTEMS.
2. When used at a cash register checkout, microphone should be installed closer to the customer rather than the cash
register, as the drawer sound could dominate the recording. It should be installed closest to the
area to be monitored and documented.
3. Avoid installing microphone near air vents, air conditioners, fans and other equipment that generate
high sound and air pressure.
4. If microphone is installed in a police interview room, room should be conditioned with any type of carpeting, acoustical
ceiling tiles, acoustical foam, etc. to reduce echo. This will enhance the quality of live and recorded audio.
5. The APR-1 and microphone should have a barrier or solid wall between them in order to avoid audio
feedback, especially when they are in close proximity to each other. If no barrier, microphone should be at least 25’
from APR-1 to avoid acoustical feedback.
