Microphones Cables
Chetan Microphone cable
is used for connecting flow level microphones or musical instruments.
Key properties of microphone cable (Mike) are ruggedness, flexibility,
flex life and interference immunity. Mike cable construction utilizes
either 1/2/3 or 4 conductor configuration. Cable selection depends on
whether the mike or instrument is of a high or low impedance design.
High impedance requires unbalanced single conductor cable while low
impedance utilizes 2/3 or 4 designs. 4 conductor mike cable-Quad mike
cables are connected by attaching 2 white conductors to 1 pin and 2 Red
Conductors to the other pin in a balanced line XLR type connecter.
Conductors joint in this manner lower the possibility of induced noise.
Digital audio has been around for over 25 years, only recently has ben
there an effort to standardize specifications. The audio engineering
society (U.S) and the European broadcast union have established an
international standard called AES / EBU. The detailed specifications of
this standard are:
- Sampling Rate: from 32 KHz to 192 Khz
- Bandwidth: from 4.096 MHz to 24.5 Mhz
- Impedance: 110 ohm ± 20 %
The
key difference between twisted pair specification for digital audio
cable and standard analog audio cable is the impedance specification.
Standard analog audio
cable impedance is 45 ohm to 70 ohm. This potential amount of mismatch
can result in signal reflection and jitter causing bit errors at the
receiver. For this reason Chetan recommends 100 to 120 ohm shielded
twisted pair cables.
Most of our Mike Cables
are available ex-stock in a wide variety of colours and packages. Many
of these are available off the shelf from our distributors. If you have
a new or unusual requirement, you can contact us.
