AKG PERCEPTION 420 large-diaphragm condenser microphone

• Back-to-back large-diaphragm multi-pattern transducer
• True condenser technology
• High sensitivity and 155 dB maximum SPL capability
• Switchable 20 dB preattenuation pad
• Switchable bass cut filter
• Legendary, pristine AKG sound quality
• Complete with spider-type shock mount and aluminium carrying case

The CK-7 houses a 35mm gold-sputtered thin Mylar capsule. The CK-7 uses high grade Polystyrene and Metalized Polypropylene capacitors in the audio path. This represents a commitment to quality, as these normally are the type of "upgrade" components that are implemented by microphone modders/hot-rodders! Any studio can proudly offer the CK-7 as a vocal mic or utility condenser due to its versatility...It exudes class visually as well as sonically.

Manufactured using the finest materials yielding a very solid feel, superb structural integrity and rugged reliability. The versatile CK-7 mic is able to produce professional results with a clean sonic character. The included Custom Retro Shockmount is superb in allowing a precise positioning of the mic while inhibiting the transfer of unwanted vibrations up into the mic. This isolation allows for superior professional results. The 3 patterns allow the CK-7 to be used in a variety of situations.

The cardioid pattern is generally best used on vocals and single instruments. The omni mode works well in incorporating some room sound into the track. The figure 8 pattern allows 2 vocalists to use the mic at the same time from opposite sides. The CK-7 has separate -10 dB pad & 80 Hz LF roll off switches....The -10dB attenuation switch can be engaged when miking very high SPL sources to keep from overloading the electronics. The 80Hz high-pass filter switch can be engaged to reduce rumble and to keep unwanted low frequencies from "muddying up" the track.

Applications.

studio vocals, acoustic guitar, mandolin, drum overheads, piano, room mic

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.
Operation output impedance:
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.
Acoustic principle: Externally polarized 25 mm (1?) dual diaphragm.
