Both the Verifact™ “DV” Microphone and APR-1 Audio Base Station
contain a 3-pin terminal block marked A, B, C
2 Conductor shielded cable, 22 gauge with a 24 gauge drain wire.
NOTE: Unshielded cable is not satisfactory for audio systems
NOTE: If DVR’s audio input and output are 3.5mm (mini jack) type, use
the appropriate adapter at one end of RCA patch cable for connection.
Check with manufacturer’s specications to determine if 3.5, audio
input/output is mono or stereo.

SENSITIVITY SWITCH OF VERIFACT™ “DP” MICROPHONE
For special installations that require less microphone sensitivity or where there is
background noise, a sensitivity switch is mounted to the microphone pre-amp (PC
Board) and has two positions, N and L:
• N represents normal sensitivity (0dB ouput into 1kΩ)
• L represents low sensitivity (-6dB output into 1kΩ)
Louroe VERIFACT™ microphones are always shipped with the sensitivity switch
in normal (N) position. Do not change unless necessary. To change the sensitivity
setting, use a small screwdriver and move slide switch from N to L position. The
switch is mounted on the back side of the microphone housing.
NOTE:
REGARDING INTERFACING ASK-4 KIT #101 WITH A DVR OR PC SOUNDCARD
The APR-1 Audio Base Station of ASK-4 Kit #101 is compatible with all commercial
DVR’s and PC Soundcards that accept line level input (0dB@600Ω). An RCA cable is
included with the kit for connecting Audio Out to Audio In of DVR. If DVR’s audio input
is a 3.5mm jack, an RCA to 3.5mm adapter (not supplied) must be attached to the plug
that connects to DVR’s Audio Input. Check with DVR’s specications to determine if the
audio input requires a stereo or mono 3.5mm plug.
PC soundcards contain a standard 3.5mm stereo Audio Input or Line Input. Do not use
Mic Input of soundcard. Louroe microphones are line level (0dB@600Ω) and will over-
drive the Mic Input. Use “Audio Input” or Line Input” of the soundcard.
WIRING CONNECTIONS AND TEST
1. Starting with the microphone, connect RED wire to Pin A, BLACK
wire to Pin B and BARE wire to Pin C. Connect other end of ca-
ble to Terminal Block on back panel of APR-1 Base Station match-
ing RED wire to Pin A, BLACK wire to Pin B and BARE wire to Pin C.
2. Plug AD-1 power supply (AC Adapter) into the Power Jack[10] located on
back panel of APR-1 rst. Then connect 2- prong block into standard 110/120
AC wall receptacle or power strip.
3. Turn “ON” power to APR-1 by rotating the Power-Volume Knob[1] clock-
wise. The green PWR[2] LED will illuminate. Adjust volume of audio by rotat-
ing the knob either clockwise to increase or counterclockwise to decrease.
Locate microphone so as not to create feedback with the APR-1. The fur-
ther the microphone is from the APR-1 the less feedback it generates. Sys-
tem works best if there is an acoustical barrier between the microphone and
the APR-1, such as a wall or room divider. If there is no wall or barrier, mi-
crophone should be mounted at least 25 ft. from the APR-1 Base Station.
4. Plug headphone into the Headphone Jack[8]. Speaker[9] output is muted
and sound is transmitted through the headphone.
5. Using the dual RCA cable (supplied), connect DVR/VCR’s AUDIO OUT jack
to APR-1’s AUDIO IN Jack[1 1] .
6. Connect DVR/VCR’s AUDIO IN jack to APR-1’s AUDIO OUT Jack[12]
7. Press “REC” on the recording device and record live audio for several minutes.
8. Press Push for Playback Switch[7] to “ON” position. Playback Indicator
LED[4] will illuminate yellow.
9. Press “PLAY” on the DVR/VCR to playback recorded audio to the APR-1.
10. Press Mute Switch[6] to mute audio heard on the speaker. Mute Indicator
LED[3] will light and no audio can be heard on the speaker on both live and
playback audio. When Mute Switch[6] is ON Playback Indicator LED[4] will
not light even when the Push for Playback Switch[7] is pushed in and the
audio is muted.
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 in cashier’s booth, microphone should be installed
closer to the customer rather than the cash register, as the draw-
er sound may dominate the recording. It should be installed clos-
est to the area that needs to be monitored and documented.
3. Avoid installing microphone near air vents, air conditioner, fans
and other equipment that generate high sound and air pressure.
4. If using a VCR, it may have both intermittent and constant speed
playback. See VCR’s manual on how to select constant speed.
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 up to 25’ (7.6 m).
