SENSITIVITY SWITCH OF VERIFACT E 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 600?)
L represents low sensitivity (-6dB output into 600?)
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 #101-E WITH A DVR OR PC SOUNDCARD
The APR-1 Audio Base Station of ASK-4® 101-E is compatible with all commercial DVR’s and PC Soundcards
that accept line level input (0dB@600?). 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 specifications 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@600?) and will overdrive the Mic Input. Use “Audio
Input” or Line Input” of the soundcard.

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 drawer sound may dominate the recording. It should be installed closest 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).
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 from 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.
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[11].
6. Connect DVR/VCR’s AUDIO IN jack to APR-1’s AUDIO OUT Jack[12].
WIRING CONNECTIONS AND TEST
Both the Verifact E Microphone and APR-1 Audio Base Station contain a 3-pin terminal block marked A, B, C.
A = 12Vdc Power Red Wire
B = Audio Black Wire
C = Ground Bare Wire
1. Starting with the microphone, connect RED wire to Pin A, BLACK wire to Pin B and BARE wire to Pin . Connect
other end of cable to Terminal Block on back panel of APR-1 Base Station matching RED wire to Pin A, BLACK wire
to Pin B and BARE wire to Pin C. Refer to drawing on page 4.
2. Plug AD-1 power supply (AC Adapter) into the Power Jack[10] located on back panel of APR-1 first. 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] clockwise. The green Power Indicator[2] LED
will illuminate. Adjust volume of audio by rotating the knob either clockwise to increase or counterclockwise to
decrease. Locate microphone so as not to create feedback with the APR-1. The further the microphone is from the
APR-1 the less feedback it generates. System 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, microphone should be mounted at least 25 ft.
from the APR-1 Base Station.
2 Conductor shielded cable, 22 gauge
with a 24 gauge drain wire.
