2 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 2 Kondensator Stormenbran (Diaphram) Akg D122 cardioid The D 112 has earned a well-deserved reputation worldwide as the best kick drum microphone ever made. Heavy-footed drummers won t faze it, because the D 112 handles up to 160 db SPL with no audible distortion. A specially engineered diaphragm with a very low resonance frequency maintains solid and powerful response below 100 Hz, while a narrow band presence rise at 4 khz punches through dense mixes with little or no added EQ. The result is a kick drum sound that ideally balances precise definition and forceful impact. The D 112 is also an excellent choice for use with bass cabinets, trombones, etc.

3 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 3 Akg Uls 414 XL II (4 stk) Har indstilling for fem karakteristikker (se nedenfor) Den har desuden indstilling for følsomheden 0, -6, -12 og -18 db Samt indstiling for bas cutoff. Max SPF140/146/152/158 db (0/-6/-12/-18 db)

5 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 5 Neumann TLM 102 BK TLM Neumann 3. Brief description The TLM 102 is a condenser studio microphone with transformerless (TLM) circuit technology and a cardioid directional characteristic. The transformerless design of the TLM 102 permits exceptionally clean sound transmission with no coloration, as well as a maximum dynamic range with low selfnoise. The microphone houses a large diaphragm capsule. It has a linear frequency response up to approximately6 khz, above which there is a broad, flat presence boost. Maximum SPL for THD 0.5% 2) 144 db

Aalborg maj 2012 Side 6 Kondensator stor-membran rørforstærket Neumann M 147 Tube Nyre Den aktive side er den med Neuman logoet Hæver svagt samme høje mellemtone område som sm58. Er ikke glad for store lydtryk Typical SPL (tube characteristic) for THD 0.5% 2) for THD < 0.5 %, 134 db 114 db Mikrofonen ligger i en særlig kasse sammen med holder og en særlig strømforsyning og et særligt kabel der sidder fast på en særlig måde på denne strømforsyning, fordi vi er for nærrige til at betale 2000 kr for et nyt.

7 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 7 Lille Membran Neumann KM 184 MT 2.stk Nyrekarakteristik Meget lineær bortset fra at bassen er dæmpet lidt. Spiller rent ved ret kraftige lydtryk; Maximum SPL140 db at less than 0.5 % THD4 (transformerløs)

8 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 8 AKG c Nyre karakteristik (lidt retningsbestem) All round mikrofon, kan tåle en stort lydtryk. Ikke så detaljeret i diskanten De fire indstillinger 0 db concenser microphone output level (7 mv/pa), flat, overloadlimit: 130 db SPL. 0 db consenser microphone outputlevel (as above) with bass-cut filter below 100 Hz slope: 12 db/octave. Applications: mainly instrumental recordings, for reducingunwanted low frequency structureborne noise. 14 db attenuation of 14 db, dynamic microphone output level,flat, overload limit: 144 db SPL. Applications: recording high sound level instruments, or prevention of overloading of mixer or amplifier inputs which are adjusted for dynamic microphones. 14 db preattenuation of 14 db (as above) with additional bass rolloff filter below 500, slope: 4 db/octave. Applications: as above, mainly vocalist, but also instrumentalrecording, close-in miking in situations

Aalborg maj 2012 Side 9 AKG SE300 B (CK93) 3stk kondensator mikrofon med en supernyre kapsel (hypercardioid) dvs. meget retnings bestemt, mikrofonen har tre indstillinger De Tre indstilllinger linæer bas cutoff, low frequency cut of 12 db-per-octave -10 db pre-electronics pad for operation at high sound pressure levels, and Spl=132 db at 1%TDM

10 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 10 Shotgun AKG C Super nyrekarekteristik Har en bass dæmpende knap Er særligt god til at lukke lyden fra siderne ude. (særligt højfrekvente lyde) Bruges derfor på teatre og film etc. Max SPL 128 db (1% TDH) Menbran størrelse 15mm..

The two red dots on the ring around the microphone head mark the longitudinal axis of the two ribbons. When setting up the microphone on stands, make sure that this axis runs vertically.

13 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 13 Nyre Hæver et lidt lysere område end SM khz og får dermed det nederste diskant område med. Sænker til gengæld bas allerede fra 200 Hz og ned. Kan tåle store lydtryk.. APPLICATION SUGGESTED MICROPHONE PLACEMENT TONE QUALITY Tom-Toms Snare Drum Guitar & Bass Amplifiers One mic on each tom, or between each pair of toms, 2.5 to 7.5 cm (1 to 3 in.) above drum heads. Aim each microphone at top drum heads. On double head toms, you can also remove bottom head and place a mic inside pointing up toward top drum head. 2.5 to 7.5 cm (1 to 3 in.) above rim of top head of drum. Aim mic at drum head. If desired, place a second mic just below rim of bottom head. 2.5 cm (1 in.) from speaker, on-axis with center of speaker cone. 2.5 cm (1 in.) from speaker, at edge of speaker cone. Sharp attack; higher frequency sound. 15 to 30 cm (6 to 12 in.) away from speaker and on-axis with speaker cone. Medium attack; full, balanced sound. 60 to 90 cm (2 to 3 ft.) back from speaker, on-axis with speaker cone. Softer attack; reduced bass. Medium attack; full, balanced sound. Most snap from drumstick. More snare sound Sharp attack; emphasized bass.

14 Gennemgang af mikrofonerne ved DJM studiet afdl. Aalborg maj 2012 Side 14 Vocals Lips less than 15 cm (6 in.) away or touching the windscreen, on axis to microphone. Robust sound, emphasized bass, maximum isolation from other sources. Proximity Effect Unidirectional microphones such as the SM57 progressively boost bass frequencies by 6 to 10 db below 100 Hz when the microphone is at a distance of about 6 mm (1/4 in.) from the sound source. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. To prevent explosive low frequency sound during close-up use, the SM57 bass response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.
