[. . . ] 912 S Bedienungsanleitung Instructions for use Notice d`emploi Istruzoni per l`uso Instrucciones de uso Gebruiksaanwijzing 912 S The boundary microphone 912 S is a high-quality, prepolarized condenser microphone with half-cardioid pick-up pattern, designed for picking up speech. [. . . ] Try to position the microphone so that the sound source (conference participant, speaker or instrument) is located in this angle area (see polar diagram). 3 Setting the operating mode and frequency response curve ³ · DIP switch bank: (visible when rear side is open) ³ Operating mode · Frequency response curve Position of DIP switches Operating mode ³ Permanently switched on (ON) Push-to-talk button (PTT) Push-to-mute button (PTM) On/off (factory preset) Position of DIP switches Frequency response curve · Low cut, can be used in all operating modes Low boost 1234 1234 1234 1234 1234 1234 Low and high boost (factory preset) linear 1234 1234 4 Operating Mode ³: Permanently switched on: disables the switch completely, the microphone is permanently switched on. Push-to-talk (PTT): The microphone is switched on as long as the membrane switch is pressed. Push-to-mute (PTM): The microphone is switched off as long as the membrane switch is pressed. On/off (factory preset): turns the switch into push to switch on, push again to switch off. Frequency response curve ·: Low cut: reduces the bass frequencies to minimize structure-born noise ­ this switch (1) is independent of the other three DIP switches and can be used in any of the following conditions (eg: you can use the low cut as well as the bass boost if placing the microphone on a small table with a high risk of structure-born noise). Low boost: extends the bass response to compensate for putting the microphone on a small table. Low and high boost (factory preset): extends the frequency response at both ends. Linear: is the natural response of the microphone. 5 Polar diagram 6 Frequency response curve dBv - 30 - 40 - 50 - 60 - 70 - 80 20 50 100 200 500 1000 2000 5000 10000 20000 Hz Low and high boost (factory preset) Rumble filter (low cut) dBv - 30 - 40 - 50 - 60 - 70 - 80 20 50 100 200 500 1000 2000 5000 10000 20000 Hz Linear ( 912) Low boost 7 Specifications Transducer principle Frequency response Pick-up pattern Sensitivity (free field, no load) (1 kHz) Nominal impedance (1 kHz) Min.
