IF-2/IF-4/IF-8 ® 6955 VALJEAN AVE, VAN NUYS, CA 91406 PH: (818)994-6498 / FAX: (818)994-6458 [email protected] / www.louroe.com AUDIO INTERFACE ADAPTERS INSTALLATION AND OPERATING INSTRUCTIONS DESCRIPTION The LOUROE IF-2, IF-4 and IF-8 are two, four zone and eight zone audio interface adapters designed for connecting up to two (IF-2), four (IF-4) or eight (IF-8) Louroe™ microphones with: ! DVR’s ! IP Network Cameras with audio inputs ! Video Servers with audio inputs ! PC Sound Card Modules IF-2 AUDIO INTERFACE ADAPTER (two audio inputs and outputs) The input side of the IF-2/IF-4/IF-8 has terminal blocks for receiving the wiring from the microphones. The output side has RCA types of output. The following cables and adaptors are included with each IF series. IF-4 AUDIO INTERFACE ADAPTER (four audio inputs and outputs) RCA to RCA type - For connection to a DVR, etc. with RCA audio inputs. RCA to 3.5mm mono type adaptor - For connection to an IP Network Camera, etc. with a 3.5mm audio input These three units also contain individual “audio level control” potentiometers for audio gain adjustment. Output from the Louroe™ microphone can be increased 10dB or decreased 30dB. WIRING CONNECTIONS IF-8 AUDIO INTERFACE ADAPTER (eight audio inputs and outputs) MICROPHONE TO INPUT SIDE OF IF-2/IF-4/IF-8 All Louroe microphones contain a terminal block marked A, B, C A = 12Vdc power (Red) B = Audio output (Black) C = Ground (Bare) WIRING REQUIREMENTS 2 Conductor shielded cable, 22 gauge with a 24 gauge drain wire NOTE: Unshielded cable is not satisfactory for audio systems If using recommended wiring, connect as follows: Red wire goes to Terminal A of microphone (12Vdc power) Black wire goes to Terminal B of microphone (Audio Output) Bare wire goes to Terminal C of microphone (Ground) After all microphones have been connected, bring other end of wiring to the IF-2/IF-4/IF-8 location and connect each microphone to the terminal blocks of the unit marked A, B, C. Be sure to properly match wire colors. If using cable from other manufacturers, color code may vary.

RCA to RCA type cable; for connection to a DVR, etc. with RCA audio inputs 2. RCA to 3.5mm mono adaptor: for connection to a DVR, IP Network Camera or Video Server that has 3.5mm audio inputs. If the receiving device contains RCA type “audio in” jacks, then connect from Audio Out of IF-2/IF-4/IF-8 to Audio In of DVR, using the provided RCA connector cables. If the receiving device contains 3.5mm mono audio inputs, connect 3.5mm RCA to mono adaptor to one end of the RCA cable (supplied) and plug that end to the DVR. Connect the RCA end of the cable to the output of the IF-2/IF-4/IF-8. Included with the units are: 2, 4 or 8 RCA to RCA cables 2, 4 or 8 RCA to3.5mm mono adaptors APPLYING POWER TO THE IF-2/IF-4/IF-8 Included with the IF-2/IF-4/IF-8 is a power supply (120V/12Vdc). Connect the small end of the 90° female plug into the 12Vdc jack, located on the input side. Then connect the two-prong large end into a standard 110/120V electrical outlet. Turn ON/OFF power switch, located behind green power LED to ON position. The green LED will illuminate, indicating power to the system. The system will now provide audio to the DVR, Soundcard Module, IP Network Camera, etc. AUDIO LEVEL ADJUSTMENT Located on the input side are potentiometers (round, with adjustment arrow) for each microphone. This is for adjusting the audio gain and to prevent overdriving or underdriving the audio signal. The adjustment arrows are shipped in the straight-up position. Turn slowly counterclockwise to lower the gain, and clockwise to increase. This will provide the desired level of audio signal into the Audio Receiving Device (DVR, Soundcard Module, etc.). A full turn clockwise increases the gain to 10dB. A full turn counterclockwise will decrease the gain -30dB. AUDIO TEST SWITCH The purpose of this switch is to indicate the presence of audio and to assure the user that the IF-2/IF-4 or IF8 is driving the audio signals into the audio input of receiving device (DVR, IP Network Camera, Video Server, Soundcard module, etc.) Located on the audio output side of IF-2/IF-4/IF-8 is a DIP switch labeled Audio Test Switch. To the left of the switch is a red LED marked Audio Indicator. For testing: 1) Select a zone that has a microphone connected to the microphone terminal block. IF-2 utilizes pins 1&2. IF-4 utilizes pins 1-4. IF-8 utilizes pins 1-8. 2) Push pin to the ON position. The red LED will illuminate, indicating audio is present. With short bursts of audio, the LED will flicker and with continuous flow of audio LED illumination is constant. Only one microphone can be tested at a time NOTE: When testing is complete, all pins on DIP switch must be in the OFF position LOUROE ELECTRONICS® 6 9 5 5 VA L J E A N AVENUE, VAN NUYS, CA 91406 TEL (818) 994-6498 website: www.louroe.com e-mail: [email protected] Page 2 of 4 FAX (818)994-6458 If_248_inst_5/11 INSTALLATION AND OPERATING INSTRUCTIONS INTERCONNECTION DIAGRAM FOR CONNECTING LOUROE VERIFACT™ MICROPHONES TO A DVR WITH MULTIPLE AUDIO INPUTS USING LOUROE MODEL IF-2, IF-4 OR IF-8 AUDIO INTERFACE ADAPTER (IF-4 used as an example) Back side of Verifact™ A Microphone Shown VERIFACT A VERIFACT N A B C A VERIFACT A N L A B C L VERIFACT N L A B C A N Red - 12Vdc power Black - Audio Output Bare - Ground L A B C A B C RED BARE BLACK 2 CONDUCTOR SHIELDED 22 GAUGE WEST PENN 452 OR EQUIV.
