Canare L-4E6S Star Quad has been the industry standard mic cable for sound touring, broadcast studio and on-location techies for over 40 years. Star Quad obtains its name from the 4-conductor style construction that minimizes the "loop-area" between twists of the conductors. This "double-balanced" pairing, reduces susceptibility to electromagnetically induced noise. The improvement in noise rejection is so noticeable, that even SCR dimmer noise (stage lighting consoles), is reduced to less than 1/10 the level found in other 2-conductor microphone cables. Canare L-4E6S Star Quad is designed for use with microphones but is also excellent for all line -level signals (e.g. mixer to power amps). The 4-conductor Star Quad arrangement, cancels electromagnetically induced noise from SCR dimmer packs, fluorescent lighting ballasts and AC power transformers. Handling noise is prevented by use of cotton filler material. Excellent frequency response is maintained due to special irradiated polyethylene insulation which provides a low capacitance dielectric.
Braided Copper Shield
Canare Star Quad cable with braided shields is super flexible. The braided copper shield of Canare L-4E6S is designed to maintain effective shielding performance, regardless of how many times the cable is unwound, bent, twisted or rewound. It is ideal for use as handheld microphone cables or extension cables. Although this cable may be a bit more expensive than standard 2-Conductor versions, the longevity of the mic cable is appreciated by touring professionals and on-location sounds techs.
When Should I Use Canare L-4E6S Star-Quad Cable?
Canare L-4E6S Star Quad is used for environments with a higher noise factor and where audio signals are in the low -50 dB or less range. This type of cable performs well under noise conditions that exceed the capacity of the 2-Conductor shielded cable, effectively shielding out over ninety percent more noise. However, should this type be routed alongside a power cable of any significant capacity it should probably be encased in metal conduit just to be safe.
With the growing demand of recent years for both greater physical comfort and savings in energy consumption, systems incorporating digital control based on the latest advances in electronics are in wide use for air conditioning and lighting systems. The wiring used for these digital control systems generates pulse -based electromagnetic noise of the kind that affects the very delicate signals used in microphone lines. Microphone cables are designed to carry a range of signals that span the spectrum from 1/100 of a volt (10 mV) to 1/1,000,000 (1 -ÝV). One small error in wiring procedure or cable selection and the entire microphone system turns into an antenna collecting the surrounding noise.
