KONDENSATORMIKROFONE FÜR STUDIO - UND MESSTECHNIK 1/2” Measuring Microphone Amplifier MV 230 digital The measuring microphone amplifier MV 230 digital connects a high-ohm impedance converter made for condenser measuring microphone capsule with a complete analogue-digital converter. Thus, the transfer of high sound pressure using long cables is made possible without any – often unnoticed – sound deterioration. Every voltage necessary for using the measuring capsules is generated internally. EMV problems, as for example caused by mobile communication close to a microphone, are drastically reduced due to the conversion into digital information by the MV 230. , It s energy efficiency allows its application in connection with mobile as well as stationary multicapsule technology. , The MV 230 supports digital transfer to AES 42-200 and AES 3-1992 (AES/EBU). It s dynamic range is the product of a simultaneous use of two 24-bit Sigma-Delta converters responsible for either low or high level signals. Dynamic range 140 dB Frequency range of signal 1 Hz- 40 kHz Sample rate 96 kHz/ 48 kHz Interface for AES 42-2001 und AES 3-1992 (AES/EBU) Energy efficient Delivery Measuring microphone amplifier MV 230 with MH 93 microphone stand adaptor, in wooden case Accessories, optional Microphone cable C 23.1 10 m XLR five pin to XLR three pin, connection to AES 42-2001 Microphone cable C 24.1 10 m XLR five pin to XLR three pin, connection to AES 3-1992 ( AES/ EBU) MICROTECH GEFELL GMBH GEORG - NEUMANN - PLATZ D-07926 GEFELL INTERNET http://www.microtechgefell.de e-mail [email protected]
