M179

The CAD M179 combines a vin-

tage capsule design with

advanced electronics. The M179

features the dual pattern version

of the original equitek e-300 cap-

sule, an externally biased capsule

with a gold sputtered 1.1" dia-

phragm.

Typical FET (field effect transis-

tor) condenser microphones use

discrete designs. This means they

use individual transistors that

must be carefully matched for

proper characteristics. Even with

careful matching, discrete designs

are inherently nonlinear. M Series

microphones use a different ap-

proach. We do not use any

discrete FETs. Instead, we use

advanced high speed OpAmps

(Operational Amplifiers).

These OpAmps are individually

laser trimmed for optimum per-

formance and have very high

gain. This allows a large amount

of negative feedback to be used to

significantly reduce any non-lin-

earity. We have also integrated a

new discrete high efficiency

power supply circuit allowing

greater dynamic range and lower

self noise.

The CAD M179 combines an ad-

vanced headamp design, with

extremely ef ficient power cir-

cuitry, and a vintage capsule

design, resulting in superior tran-

sient response, low distortion, low

noise, and high output level. The

bottom line is we believe you will

find the M179 to have a remark-

ably open and clean sound that

will enhance any project.

Description

The CAD M179 is a variable-pattern side address microphone designed for

professional recording and broadcast applications. The implementation of high

speed, low noise, low distortion electronics makes the M179 the ideal candidate

for the most critical applications.

The CAD M179 incorporates a number of unique features

including:

•Continuously variable pattern with a "hard" cardioid center detent.

•Large 1.1" dual diaphragm external bias condenser capsule.

•Gold sputtered diaphragms.

•High SPL capability (143 dB SPL with pad)

•Transformerless balanced output circuits.

•20 dB non-capacitive pad

•6dB/Octave @ 100Hz high-pass filter

•Stainless steel internal pop/EMI filter.

Level)

The pattern control knob on the M179 has a

center detented cardioid position. This allows the user to

quickly and consistently lock the mic in a "hard" cardioid

pattern. By turning the knob clockwise from the center,

the pattern varies continuously from cardioid, to

subcardioid, through omnidirectional. By turning the

knob counterclockwise from the center, the pattern varies

continuously from cardioid, to hypercardioid through

bidirectional (Fig.8). This allows the user to adjust to the

optimal pattern needed for almost any recording or live

situation.

Getting Started

The high gain and wide bandwidth of the M179 microphone will easily overload the inputs

of many professional mixing consoles if adequate precautions are not taken. This is especially

true if the microphone is going to be used on percussion or amplified electronic instruments.

If you have never used this microphone before, we strongly recommend that you initially

reduce the system gain by doing one or more of the following:

•Enable the pad switch on the input of your mixing console.

•Start with the input trim control on your mixing console turned down to a low

level.

•Enable the -20 dB pad switch on the M179 microphone.

The M179 requires a 24-52V phantom power supply, delivering at least 8mA for proper

operation.

User Techniques and Applications

The CAD M179 can be used in a broad number of applications, ranging from live

reinforcement to the most critical studio situations. The M179 is ideal for vocals and voice

overs, yet it also excels at some of the most demanding instrumental projects. The M179 is

great for virtually all acoustic, wind, and amplified instruments. The M179 has been proven

to be outstanding in all of these applications and more. Its uncolored sonic characteristics

allow you to decide how an instrument or vocal will sound in the mix.
