[. . . ] 500647 3 Features Frequency response and sensitivity tailored for speech, vocal and instrument miking Very unobtrusive due to flat design Extremely rugged sound inlet basket Rubber damping plate on base Mounting slots for mounting the micorphone to e. g. table tops Gold-plated XLR connector Integrated electronics (instead of in-line pre-amp) Delivery includes 912 microphone Pouch Instructions for use Warranty Certificate 4 Positioning the microphone Boundary microphones make use of the pressure effects at a room boundary and need to be mounted on a flat surface: Position Altar or lectern: on a sound-reflecting surface Resulting sound Less room resonance portions or comb filter elements; improved speech intelligibility and greater gain reserves in contrast to freestanding microphones Less room resonance in contrast to freestanding microphones Commentary Unobtrusive due to flat design; no microphones in the field of vision Conference rooms: lying on the table; directed towards the conference participants *) Microphones must not be covered by papers, folders or similar objects 5 Theater stages: lying at the edge of the stage and directed towards the stage; as spot microphone of the PA system or for monitoring purposes in the theater cloakrooms Less room resonance in contrast to freestanding microphones; improved speech intelligibility Excellent rejection of rumble noise; if necessary, place the microphone on a soft pad (e. g. If necessary, combine with overhead microphones (e. g. Sennheiser ME 36 with MZH 30 B & MZC 30) Grand piano / piano: mounted to the inside cover (= sound-reflecting surface) of the piano or lying in the instrument or on the floor underneath the piano Very transparent and powerful sound; stereo sound image can be shaped individually, depending on microphone position chosen Instrument is easy to mike, even when the cover is closed; excellent protection against crosstalk into other microphone channels and reduced volume on stage *) The cardioid pick-up pattern has an opening angle of approx. Try to position the microphone so that the sound source (conference participant, speaker or instrument) is located in this angle area (see polar diagram). 6 Polar diagram 30° 0° 0 5 10 60° 15 20 25 90° dB 90° 60° 30° 120° 120° 150° 150° 180° 125 250 500 1000 Hz Hz Hz Hz 2000 4000 8000 16000 Hz Hz Hz Hz Frequency response curve dBv - 20 - 30 - 40 - 50 - 60 - 70 20 50 100 200 500 1000 2000 5000 10000 20000 Hz 0°, 1 m 0°, 5 cm 7 Specifications Transducer principle pre-polarized condenser microphone 20­20, 000 Hz half-cardioid Frequency response Pick-up pattern Sensitivity (free field, no load at 1 kHz) 10 mV/Pa Nominal impedance (at 1 kHz) < 100 Min. terminating impedance 1 k Phantom powering 48 V / 1. 1 mA Max.
