[. . . ] 914 Bedienungsanleitung Instructions for use Notice d`emploi Istruzioni per l`uso Instrucciones para el uso Gebruiksaanwijzing 914 The cardioid 914 is a pre-polarised condenser microphone designed for demanding applications which require a wide frequency response, high sound pressure level, fast transient response and a compact design. [. . . ] Note: We recommend that you mute the corresponding microphone channel on the mixing console before connecting and disconnecting the microphone cable, switching on and off the phantom powering or setting the switches (see figure above). 13 Frequency response curves with different sensitivities dBv - 35 - 40 - 45 - 50 - 55 - 60 - 65 - 70 20 50 100 200 500 1000 2000 5000 10000 20000 Hz 0 dB -10 db -20 db Adjusting the bass filter (B) The 914 has been designed for an extended lowfrequency bass response. With certain live or close instrument miking applications, an over-emphasis of the low frequencies can occur.

If necessary, remove unwanted lowfrequency signal portions by high pass filtering. Attention: When closing the hi-hat, a strong air current is created on the edge. If the microphone is positioned too close to the edge, interfering noise due to the air current can occur. If the overhead microphones are only used for picking up the cymbals, unwanted signal portions can be attenuated by high pass filtering. In order to prevent interference due to crosstalk between adjacent sound sources, try to position the microphone so that the interfering sound source is located in the angle area of the highest cancellation of the microphone (approx. 180°, see polar diagram). 15 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 Pin assignment of XLR-3 connector + + 2 3 1 1 3 2 + + 2 3 1 XLR XLR XLR 16 Specifications Transducer principle pre-polarised condenser microphone 20­20, 000 Hz cardioid 48 V/2. 2 mA Frequency response Pick-up pattern Phantom powering Sensitivity (free field, no load at 1 kHz) 7 mV/Pa; 2. 3 mV/Pa / 0. 7 mV/Pa (with pre-attenuation) Equivalent noise level A-weighted (DIN IEC 651) 19 dB CCIR-weighted (CCIR 468-3) 30 dB Pre-attenuation 0, -10, -20 dB Bass filter linear roll-off 130 Hz, 6 dB/oct.
