9: Using a single microphone to mic up a flute. 4.6.7 Clarinet Fig. 10: Clarinet. Aim the microphone at the middle 4.6.8 Tenor and Soprano of the instrument from a distance of Saxophones about 2 to 3 1/2 feet (50 cm to 1 m). Fig. 11: Tenor saxophone (a), soprano saxophone (b). C 414 XLS / XLII 4.6.9 Trumpet, Trombone Fig. 12: Trumpet (a), trombone (b). 4 Using Your Microphone Place the microphone about 1 foot (30 cm) in front of the instrument, slightly off the bell axis. Switch in one of the preattenuation pads. Using the supplied windscreen will help reduce blowing noise. a b 4.6.10 Grand and Upright Pianos Fig. 13: Grand piano. Grand piano: Aim a single C 414 or an XY, MS, or ORTF pair of C 414s at the middle strings from a height of 5 to 7 feet (1.5 to 2 m). For a rock/pop sound, place two C 414s roughly 8 to 16 inches (20 to 40 cm) above the strings. Align mic 1 with the treble strings and mic 2 with the bass strings, both at a point about 6 inches (15 cm) behind the dampers. Upright piano: Use the same technique as for the grand. Open the lid and have the microphones "peek into the instrument" from above. Fig. 14: Upright piano. C 414 XLS / XLII Electric guitar: Position the microphone 3 to 6 inches (8 to 15 cm) in front of the speaker, aiming at a point off the speaker diaphragm center. Use the bass cut and a preattenuation pad. You may want to use an additional distant microphone. Electric bass: Use the same technique as for the electric guitar. You can use a DI box to add the direct signal of the line output on the bass amp to the microphone signal. 4 Using Your Microphone 4.6.11 Electric Guitar and Bass Fig. 15: Electric guitar. Overhead miking: 4.6.12 Drums Place two C 414s in an AB or XY configuration about 2 3/4 to 4 feet (80 to 120 cm) above the drummer's head. This technique will pick up the entire kit, delivering a highly natural sound. Use little or no EQ! Hanging and floor toms: Use one microphone for each tom or for every two toms, aligning the microphone with the rim of the top head. To reduce leakage from other instruments, attenuate the HF range above 10 kHz using the channel EQ(s). Fig. 16: Typical drum kit. Kick drum: Remove the resonance head and place the microphone right inside the shell. Be sure to switch in the 18-dB preattenuation pad because sound pressure levels may rise to 160 dB. C 414 XLS / XLII 5 Cleaning 5.1 Microphone • Use a soft cloth moistened with water to clean the surface of the microphone body. 5.2 Windscreen • Wash the foam windscreen in mild sudsy water. Do not use the windscreen before it has dried completely. 6 Specifications Type: 1-inch large-diaphragm pressure gradient microphone Polar patterns: nine, selectable Open-circuit sensitivity: 23 mV/Pa (-33 dBV ± 0.5 dB) Frequency range: 20 to 20,000 Hz (see frequency response traces) Impedance: . 200 ohms Recommended load impedance: . 2200 ohms Bass cut filter slopes: 12 dB/octave at 40 Hz and 80 Hz; 6 dB/octave at 160 Hz Preattenuation pads: -6 dB, -12 dB, -18 dB (selectable) Equivalent noise level to IEC 60268-4: 20 dB (0 dB preattenuation) Equivalent noise level to IEC 60268-4 (A-weighted): 6 dB-A (0 dB preattenuation) Signal/noise ratio re 1 Pa (A-weighted): 88 dB Max.
