- Premium electronic components and gold-plated internal and external connectors
- Subsonic filter eliminates rumble from mechanical vibration below 17 Hz
- Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
- 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect
- Integrated three-stage 'pop" protection grille reduces plosives and other breath noise
- Internal shock mount reduces handling and stand noise
Performance Characteristics
- Extended frequency response
- Low self noise
- Exceptional low-frequency reproduction
- High output level
- High input SPL capability
- No crossover distortion
- Extremely uniform polar response

- Protective Velveteen Pouch
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.

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.
