[. . . ] Do not expose the device to dripping or splashing and ensure that no objects filled with liquids, such as vases or coffee cups, are placed on the device. Should a spillage occur, unplug the device and have it checked by a technician. Do not attempt to service devices yourself as opening or removing covers may expose dangerous voltage or other hazards. If devices are opened by customers in breach of this instruction, the warranty becomes null and void. Servicing is required if a device has been damaged in any way, such as mains cable or plug damage, liquid has been spilled, objects have fallen inside, the device has been exposed to rain or moisture, does not operate properly or has been dropped. Intended use of the device "Intended use" means that the device should be used within the operating conditions and limitations described in this instruction manual. "Improper use" means using the device other than as described in this instruction manual, or under operating conditions which differ from those described herein. 3 IAS-MO 2000 SET The IAS-MO 2000 Set system consists of the following main components: 1 MO 2000 Set optical microphone system 1 MZWW 2000 weather and wind protection The IAS-MO 2000 Set system meets the requirements of the ATEX directive. The MO 2000 H optical microphone consists of an opto-acoustic microphone head which is fitted with a fixed 3 m double fiber optic cable. Power is supplied via an external wide voltage range power supply unit. The MO 2000 H is an omni-directional microphone designed for picking up airborne sound. The components of the MO 2000 H microphone head (outside dimensions: 1/2 inch) are made of plastic suitable for permanent stationary use in areas where aggressive substances (gases, salts, moisture) or radiation are present. All components of the MO 2000 H microphone head are metal-free, including the fiber optic cable feed. The main areas of application of the optical microphone are acoustic measurement and communication tasks in industrial environments and EMC-sensitive areas as well as medical magnetic resonance imaging and magnetoencephalographic measurement (MEG). Other applications are to be found in the field of non-detectable acoustic surveillance. 4 Delivery includes IAS-MO 2000 Set 1 MO 2000 H optical microphone with 3 m fiber optic cable 1 MO 2000 CU central unit 1 mains unit with different country adapters 1 GA 2 rack adapter 1 carrying case 1 instruction manual Optical microphone Fiber optic cable MO 2000 CU 0 20 40 +/- 15dB 0 OVERLOAD dB GAIN Mains unit LEVEL MZWW 2000 1 pipe 1 SCRJ-GOF socket (inside the MZWW 2000) 1 cover with gasket 1 plate/mounting frame 1 SCRJ-HCS socket (fiber optic connector set) 1 windshield basket 1 MZQ 2000 microphone clamp Pipe Microphone clamp Windshield basket Fiber optic connector set (not preassembled) 5 Product overview IAS-MO 2000 Set ³ · » ¿ 0 20 40 +/- 15dB 0 OVERLOAD dB GAIN LEVEL AF OUT BAL/UNBAL OPTICAL MIC INPUT DC IN 12V/150mA LEV 6dBu MAX ´²¶ º ¾ ³ Gain switch (coarse adjustment) » OVERLOAD LED ¿ ON/OFF button ´ Cable grip for power supply DC cable µ¸ · Level control (fine adjustment), with 0 dB mark ² DC socket for connection of power supply unit (DC IN) ¶ Audio output (AF OUT BAL), XLR-3M, balanced º Audio output (AF OUT UNBAL), BNC socket, unbalanced ¾ Type plate µ SC optical input for microphone ¸ SC optical output for microphone 1 4 5 7 6 2 3 Optical microphone SC duplex connector Mains unit US adapter UK adapter EU adapter (preassembled) Fiber optic connector 6 Putting the system into operation CAUTION!Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining. You can set up the device on an even surface or mount it into a 19" rack. Note: Do not fit the rubber feet when rack mounting the device. Setting up the device To ensure that the device cannot slip on the surface on which it is placed, fix the supplied four self-adhesive soft rubber feet to the base of the device. Ensure that the base of the device is clean and free from grease before fitting the rubber feet. Fix the rubber feet to the base of the device by peeling off the backing paper and fitting them as shown. Rack mounting CAUTION!When installing the device in a closed or multi-rack assembly, please consider that, during operation, the temperature within the rack may rise significantly. Make sure not to affect the ventilation required for safe operation or provide additional ventilation.
