[. . . ] 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. Refer all servicing to qualified service personnel. 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 MO 2000 Set The MO 2000 Set optical microphone system consists of the following main components: MO 2000 H optical microphone MO 2000 CU central unit 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. The fiber optic cable is connected to the MO 2000 CU central unit. 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 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 carrying case 1 instruction manual Optical microphone Fiber optic cable Mains unit 0 20 40 +/- 15dB 0 OVERLOAD dB GAIN LEVEL MO 2000 CU 5 Product overview 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 µ ³ Gain switch (coarse adjustment) · Level control (fine adjustment), with 0 dB mark » OVERLOAD LED ¿ ON/OFF button ´ Cable grip for power supply DC cable 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 duplex optical connection for microphone ¹ ¸ Optical microphone ¹ SC duplex connector Mains unit US adapter UK adapter EU adapter (preassembled) 6 Putting the system into operation Fitting the device feet 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. Do not place the central unit on delicate furniture surfaces. 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.
