STUDIO PROJECTS C4 CONDESER STEREO PAIR MICROPHONES

The C4 is small diaphragm condenser microphone featuring interchangeable capsules,
switchable -10dB pad/high pass filter and a linear low-noise, solid state amplifier body.
The microphone?s modularity makes it a useful multi-purpose tool intended for all-around
use on stage, on location and in studios of all caliber.
As a cardioid (pressure gradient) microphone, the C4 provides excellent pickup of on-axis
sources while attenuating extraneous sound occurring from around and behind the mic.
This makes it ideal for close miking of individual instruments where bleed from other nearby
instruments or sound is undesirable. The C4 cardioids also make excellent stereo pairs for
coincident and near-coincident miking techniques such as X-Y and ORTF. Additionally the
C4?s are quite useful on a drum kit as overheads and on toms.
Used as an omni-directional (pressure) microphone, the C4 offers a warm tonal response
and is recommended especially for close miking in favorable acoustical environments. There
is very little off axis coloration owing to the inherent physical properties of pressure capsules,
and it is this - combined with the low self-noise of the microphone amplifier that makes the
C4 omni an excellent ambience mic ?especially in pairs. In a good room, a pair of omni?s
can provide a vibrant and live feel to recordings, which is not achievable through the use of
directional microphones.
Recommended uses are, spaced pair omni, Jecklin disc (OSS), piano, guitar, drum overheads
and room miking. The C4 is available in pairs with shockmounts, windscreens and case.

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.

The AVANTONE CK-6 is truly a gorgeous looking and sounding microphone. The design, character and performance can be compared directly to fine studio-standard FET mics…but at a fraction of their cost!

The rugged CK-6 microphone body and capsule assembly are precision machined of Brass. Aesthetically the compact body features an elegant Metallic Cabernet Wine-Red finish, accented with polished nickel trim and capsule assembly. Manufactured using the finest materials yielding a very solid feel, superb structural integrity and rugged reliability.

This Transformerless CLASS A FET Microphone w/ 32mm gold sputtered thin Mylar capsule is designed with circuitry that will yield pleasing professional results comparable to much more expensive designs. It also features -10 dB pad  &  80 Hz LF roll off switches for varied recording situations.
 
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.
 
Applications

Studio vocals, acoustic guitar, mandolin, drum overheads, piano, etc…
