God artikel om mikrofoner generelt http://en.wikipedia.org/wiki/Microphone
Nyttig forkortelse: SPL betyder lydtryk (Sound Pressure Level).

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.

Neumann TLM 102 BK
TLM 102 - 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

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) 114 dB
for THD < 0.5 %, 134 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.

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.

Hæver et lidt lysere område end SM58 3-10 kHZ og får
dermed det nederste diskant område med.
Sænker til gengæld bas allerede fra 200 Hz og ned.

APPLICATION
SUGGESTED MICROPHONE PLACEMENT
TONE QUALITY
Tom-Toms
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.
Medium attack; full, balanced sound.
Snare Drum
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.
Most “snap” from drumstick. More “snare” sound
Guitar & Bass Amplifiers
2.5 cm (1 in.) from speaker, on-axis with center of
speaker cone.
Sharp attack; emphasized bass.
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.

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.
