Applications
Some typical applications for the KSM27 are listed below. Microphone use, however, is a matter of personal taste. The KSM27 may be used for a variety of applications other than those listed.
- Voice -- solo, background, voice-over, broadcasting
- Acoustic instruments -- such as piano, guitar, drums, percussion, strings
- Electric instruments such as guitar and bass
- Wind instruments -- brass and woodwind
- Low frequency instruments -- such as double bass, electric bass, kick drum
- Overhead miking -- drums or percussion
- Ensembles -- choral or orchestral
- Room ambiance pick-up -- guitar amplifier or drums
Both the acoustic environment and microphone placement strongly affect the sound obtained from miking a source, especially with a high resolution microphone like the KSM27. You may need to experiment with microphone placement and room treatments to achieve the best overall sound for each application.

NT1000 - ?Pure Performance? Ultra Versatile 1? Studio Condenser Microphone.
With its ultra low 6 dBA self-noise and transformer less SMT circuitry, the
R?DE NT1000 exhibits exceptional performance when recording both vocals
and instruments in the studio.
Voiced for ?application versatility?, the NT1000 has been hailed by many as the
ultimate drum over-head and grand piano mic selection. The NT1000 is also
equally at home as a first call vocal mic. With its Australian made 1? HF-2 capsule
incorporating internal shock mounting, the NT1000 boasts a 134 dB dynamic range,
and 140 dBA SPL capabilities and a 20 Hz ? 20 kHz frequency response.
Built of a heavy-duty cast metal satin nickel body, the NT1000 incorporates a
high-strength, heat-treated mesh head, and comes supplied in a zip pouch with a
stand mount.

| The C 414 B/XLS has been carefully designed to maintain the legendary sonic character of the C 414 family while integrating new features and performance enhancements made possible by new technology. The C 414B/XLS is designed to deliver accurate pickup of all acoustic instruments and voices.
The microphone's 5 pickup patterns are easily selectable via an electronic switch with LED indication and offer the selection of omnidirectional, cardioid, wide cardioid, hypercardioid and figure-eight patterns.
The pickup pattern selector switch utilizes a dual-color LED indicator that provides visual indication of the pattern selected and also changes from green to red to indicate if the microphone's output electronics are being overloaded. The pattern selector can also be used to "lock" the microphone's switch settings by pressing and holding it for 3 seconds.
On the rear of the microphone, an electronic switch allows the selection of -6 dB, -12 dB and -18 dB pre-attenuation levels which are accomplished by changing the polarization voltage to the capsule. The C 414 B/XLS has switchable bass cut filters of 12 dB-per-octave at 40 Hz and 80 Hz, and a 6-dB-per-octave filter at 160 Hz for control of proximity effect. On-axis sensitivity for all patterns is 23 mV/Pa and its self-noise is an extremely low 6 dB-A.
The C 414 B/XLS has a transformerless output and all-metal chassis, making it immune to electrical interference and RF from digital equipment, video monitors and wireless systems. It comes complete in an all-metal road case with the AKG H-85 shock mount, a PF80 external two-stage pop filter, a W414X external windscreen and an individually-measured chart showing the response curve of the microphone. It is also available in factory-matched stereo pairs packaged with a H50 stereo bar instead of the external pop filter.
The C 414B/XLS is built in Vienna, Austria and comes with a three-year limited parts and labor warranty.

NT2-A - ?The Legend Continues? Multi Pattern 1? Condenser Microphone.
The new NT2-A carries on the tradition forged by the now legendary R?DE NT2.
A professional large capsule (1?) studio microphone incorporating three-position
pick-up patterns, pad and high pass filter switches conveniently located on the
mic body.
At the heart of the NT2-A is the Australian designed and manufactured HF1 dual
diaphragm capsule. The frequency and transient response of this new transducer
has been voiced to complement today?s modern recording techniques, and yet still
evoke the silky smooth character of the legendary microphones of the 50?s and 60?s.
These features provide the flexibility and superlative audio characteristics that make
the NT2-A one of the most versatile condenser mics available.
The NT2-A?s variable controls allow switching between Omni, Figure 8, and Cardioid
polar patterns. The three position high-pass filter provides a flat response or an 80Hz
and 40Hz high pass filter to be selected. Finally the microphones Pad can be switched
between 0 dB, -5dB and -10dB. The NT2-A comes in a soft pouch with an M2 stand mount.
SPECIFICATIONS:
Features:
The Australian designed and manufactured HF1 1? edge terminated, gold sputtered, dual
5 um diaphragm capsule. 3-position variable polar pattern: Omni, Cardioid & Figure 8; all
controlled on the mic. 3-position variable high-pass filter: Flat, 80 Hz or 40 Hz. 3-position
variable pad: 0 dB, -5 dB or -10 dB. Ultra low noise, transformerless SMT circuitry. Wide
dynamic range. High strength heat-treated steel mesh head. Durable satin nickel finish.
Internal capsule shock mounting. Supplied complete with soft pouch and clip. Designed
and manufactured in Sydney, Australia.
Operation power:
The NT2-A is designed to operate from phantom power to the P48 standard. The NT2-A will
operate between 44V and 52V applied with positive polarity to pin 2 and pin 3 of the output
XLR connector.

The NT2-A will operate satisfactorily into a load impedance as low as 1 kΩ. If a load below this
is used, the output signal level will be reduced. The NT2-A output is balanced between pin 2 (hot)
and pin 3 (cold). Pin 1 is ground.
