Louroe Electronics ASK-4 401 - Manual (Page 3)

MICROPHONE CONNECTIONS
The color code for recommended wire is red, black and a bare wire. On the backside of Verifact A Microphone is a 3-pin
terminal block marked A, B, C. Connect as follows:
Red wire goes to terminal A (12 Vdc Power)
Black wire goes to terminal B (Audio Out)
Bare wire goes to terminal C (ground)
Use the same procedure for the second Verifact™ A Microphone.
CONNECTION TO RN-2 MICROPHONE MIXER
The RN-2 Mixer has an input side and output side.
Bring wire from microphone #1 to the input side and connect as follows:
Wire from terminal A of microphone #1 goes to terminal A
Wire from terminal B of microphone #1 goes to terminal B1
Wire from terminal C of microphone #1 goes to terminal C
Bring in wire from microphone #2 and connect as follows:
Wire from terminal A of microphone #2 goes to terminal A (with Mic #1)
Wire from terminal B of microphone #2 goes to terminal B2
Wire from terminal C of microphone #2 goes to terminal C (with Mic #1)
CONNECTION TO APR-1 AUDIO BASE STATION
The OUTPUT side of Model RN-2 has a terminal block marked A, B, C, SP. Using same 2 conductor shielded cable, 22
gauge with a 24 gauge drain wire, connect as follows:
1. Red wire goes to terminal A of RN-2 output side
2. Black wire goes to terminal B of RN-2 output side
3. Bare wire (drain) goes to terminal C of RN-2 output side
SP terminal is not used for this application
4. Bring wire from output side of RN-2 to Model APR-1 Audio Base Station. Rear panel of APR-1 contains a
terminal block marked A, B, C. Match the wiring from RN-2 output and connect as follows:
5. Red wire from RN-2 output goes to terminal A of Model APR-1
6. Black wire from RN-2 output goes to terminal B of Model APR-1
7. Bare (drain) wire from RN-2 output goes to terminal C of Model APR-1
NOTE: “SP” terminal of RN-2 is not used with this application.
APPLYING POWER TO APR-1 AUDIO BASE STATION
Included with ASK-4® 401 is a power supply, 120V step down to 12Vdc. First connect the small end 2.1mm female plug to
the Power Jack [10], located on rear panel of APR-1. Then connect power block to a standard 120V electrical outlet. This
will power up the system.
MICROPHONE BALANCE CONTROL
Located on the output side of the RN-2 Mixer is an adjustment potentiometer for microphone balance. If more volume is
desired from microphone connected to the B-1 input side, turn potentiometer counterclockwise toward the B-1 arrow. If
more volume is desired from microphone connected to the B-2 input side, turn potentiometer clockwise toward the B-2
arrow. For equal volume from the two microphones, position potentiometer to the center.
INSTALLATION TIPS
1. The Model A Microphone is designed for installation to a ceiling or wall. Each microphone will pick up normal sounds
approximately 15’ away in all directions or within a 30’ diameter circle.
Again, the ASK-4® 401 is NOT a two zone audio monitoring system. The two microphones are
combined for expanded zone coverage and function as a single zone system.
2. Avoid installing microphones near air vents, fans or other equipment that generate excessive noises.
3. To avoid audio feedback, there should be a barrier such as a wall between the microphone and the APR-1 Audio Base
Station. If there is no barrier, microphone should be at least 25’ from the APR-1.
4. For special installations that require less microphone sensitivity, a slide switch is located on the back side of
Verifact A Microphone marked N and L (normal and low) with a small screwdriver, move slide switch to L position.
NOTE: Terminal “SP” of RN-2 is
not used with this application.
