INSTALLATION AND OPERATING INSTRUCTIONS

ELECTRICAL CONNECTION

The Model A 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.

A represents	+12 Vdc Power
B represents	Audio Output
C represents	Ground

If using West Penn 452 or equivalent with same color code, connect:

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

CONNECTING VERIFACT® A 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:

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 ® A 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.

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 sensitivity switch can be moved from “N” position to “L” position to help reduce background noise. “N”is normal, “L” is low

INSTALLATION TIPS

1.Use 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.
