The Verifact E-AGC is an omni-directional, low
impedance, electret condenser microphone with built-in
preamp and automatic gain control. 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 E-AGC produces line level output (0 dB) and
can be located up to 1,000’ from the Louroe base
station. The gain of the microphone can be adjusted
through a potentiometer up to +10dB. The microphone
preamp is mounted inside a singe gang Bell Box
housing that is designed for outdoor use or in moist
environment. The Verifact E-AGC is compatible with
all Louroe Audio Base Stations or Louroe Audio
Interface Adapters.

MICROPHONE CONNECTION
If using West Penn 452 or equivalent with same color code, starting from
right to left of the pluggable connector, connect as follows: (See
connections on right)
1. Red wire (12 Vdc) connects to terminal A or right hand most
terminal of the pluggable connector.
2. Black wire (audio out) connects to terminal B or middle terminal
of the pluggable connector
3. Bare wire (ground) connects to terminal C or left hand most of
the pluggable connector.
4. After all 3 wires are tightened in place on the pluggable
connector, plug it in to the 3 pin header located on the
pcboard. See interconnection diagram on next page.
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.
A represents +12 Vdc Power
B represents Audio Output
C represents Ground
A 3-pin header is located on the back of the microphone housing, marked A, B, C.
CONNECTING VERIFACT EGC MICROPHONE TO A LOUROE BASE STATION OR AUDIO
INTERFACE ADAPTER
CONNECTING VERIFACT™ E-AGC 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)
All Louroe audio base stations and Interface Adapters 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 (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)
