The Canare L-4E3-4P 200M 4-Channel Star Quad Microphone Cable (656' / 200 m) is a 25 AWG Star Quad snake cable with braided shields. Each channel is completely isolated and consists of 4 conductors surrounded by an overall braided shield encased in a color coded striped PVC jacket. The 4-conductor style construction minimizes the loop area between twists of the conductors. This double balanced pairing reduces susceptibility to electromagnetically induced noise.

Fine conductor stranding for flexibility facilitates roll up and easy payout. Large numbers of thin wire strands are used in the copper conductors and overall braided shield. A special compound PVC outer jacket is extruded that remains pliant at extremely low temperatures with no wait between cold shipping and installation. The 4-conductor design provides superior EMI and RFI noise rejection in problem areas on the stage.

This Star Quad cable is designed for use with microphones but is also excellent for all line-level signals (e.g. mixer to power amps). The 4-conductor 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. Good frequency response is maintained due to special irradiated polyethylene insulation which acts as a low capacitance dielectric

Good crosstalk characteristics allow different signals (-120 dB mic, 4 dB line, 10 dB code levels) to be used in adjacent channels.

Note:

All Canare DT12 Snake assemblies are built using our road-worthy and flexible L-4E3-12P cable.

Filler

The filler in the cable prevents stretching and twisting of the inner conductors which can cause noise

Conductors

Utilizes high-conductivity, annealed copper wires, stranded to form flexible conductors and shields

Jacket

The PVC outer jacket is tough, strong, and durable with good flexibility. These qualities are retained even at very low temperatures, reducing the chance of the cable stiffening or cracking.

Insulation
On irradiation, the polymer insulation becomes extensively cross-linked, chemically inert, water resistant, and remains flexible at very low temperatures. Irradiated PE is heat resistant, and the insulation is less likely to shrink back, flow, or char when soldering, so you save initial and rework time, and achieve more reliable connections.

Shield

Spiral (serve) shields are not used because they can spread apart with use. The cable's shield is made using many thin copper strands in a densely woven braid. It is very flexible and offers appreciable noise rejection

Note:

In order to maximize noise rejection, Star Quad must be properly wired to the XLR-3 connector (or terminal block). Note: The high shield density makes it is somewhat difficult to push back the braid and pull the inner conductors through. Instead, we strongly recommend unbraiding the shield by combing it out with a pointed tool, beginning at the end of the cable.

Application

Ideal for multiple audio lines, portable applications, audio rack wiring, & PA systems
