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 1k W
L represents low sensitivity (-6dB output into 1k W
®
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.

A = 12Vdc Power
B = Audio
C = Ground

2 Conductor shielded cable, 22 gauge with a 24 gauge drain wire.
West Penn 452 or equivalent
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 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 2prong 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.
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] .
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.
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).
