The ASK-4® 401 is a single zone audio monitoring system with two Verifact™ A Microphones that
work together for extended zone coverage. Model APR-1 Base Station contains a 3” speaker for
both live audio and audio playback. The system is designed to interface with a DVR, VCR or other
audio devices that accepts line level input.

SEPARATE ZONES. Both microphones serve as one audio zone with approximate
coverage of 30’ x 60’ in a normal acoustical environment.

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.

OPERATION TEST
After all wiring connections are complete and APR-1 is connected to a recording device:
1. Turn Power-Volume Knob [1] to “ON”. Power Indicator[2] will illuminate.
2. Adjust volume by rotating knob Clockwise to increase. Counterclockwise to decrease volume.
3. Create sound for the microphone to pick up. Audio should be transmitted to the Speaker[9] in APR-1 Base
Station. Live audio can be monitored while recording as well.
4. For recording audio, follow instructions given for the recording device. Audio is passed into the recorder and
through the APR-1 speaker.
5. For audio PLAYBACK from the recorder back into the APR-1, press the Push for Playback switch [7] to ON
position and the YELLOW LED lights [4].
6. For private audio monitoring, connect a stereo headphone with 3.5 mm plug into Headphone Jack [8] located
on front panel of APR-1. Headphones with 8 to 600Wimpedance can be used. While monitoring with
headphones, live audio from the APR-1 speaker will be muted but can still be recorded.
7. 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 REGARDING INTERFACING ASK-4® 401 WITH A DVR
The APR-1 Audio Base Station of ASK-4® 401 is compatible with all commercial DVR’s. If DVR contains a
3.5mm “Audio In” Jack, a 3.5mm Adapter must be connected to that end of the RCA cable provided with Kit
#101. Check with the DVR’s manufacturer to determine if the audio input requires a stereo or mono 3.5mm
plug.
