Vtech AV Systems - Canare Speaker And Mic Cables

canare 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 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 fromscr 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. canare star quad cable is super flexible. we use large numbers of thin wire strands in the copper conductors and overall braided shield. we extrude a special compound pvc outer jacket that remains pliant at extremely low temperatures with no wait between cold shipping and installation.

technical note the signal generated by a microphone during quiet periods can be very low in level, -70db to -120db (0.3 millivolts to 1 microvolt). the cable that must carry this signal to the mixer is very sensitive to electromagnetic interference (emi), radio frequency interference (rfi) and electrostatic coupling of hum and noise. mechanical vibration, bending, flexing (handling noise) and ambient temperature fluctuations can cause detrimental capacitance changes within the microphone cable. canare cables are carefully designed and manufactured to very close tolerances using the highest quality materials available so that low level microphone circuits will not be affected by these outside disturbances. the difference is clearly measurable and audible
