Miniature Balanced Mic.
Cables / Lavalier Mic. Cables
W2697
W3031
W2901
These miniature microphone cables feature necessary mechanical strength
(tensile strength and long flex life) and flexibility for lavalier microphones
and other applications. All balanced configuration. Part No. W3031 cable
is exactly same construction as Part No. W2697 cable except for shield
structure. Part No. W2697 cable is constructed with served (spiral) shield,
while Part No. W3031 cable is constructed with braided shield. Part No.
W2901 is specially designed with better tensile strength and longer flex
life, sacrificing some sound quality, and creating a slightly more difficult
soldering job because of used copper-tin alloy conductor, this cable is
mechanically very strong and durable. Of couse, its cost is higher.
| Note: |
Any specific countermeasure against microphonics
( noise ) for high impedance microphones is not taken for these three
lavalier microphone cables. |
