Please contact with SIGMARCA Cables RCA Cables can be used to connect a variety of audio and video devices, such as camcorders, to TVs or stereos to speakers. Most high-end camcorders have all three RCA jacks, so the signal entering or leaving the device goes through three separate channels-one video and two audio-resulting in a high-quality transfer. Lower-end camcorders usually have only one jack, called a stereo jack, which combines all three channels. This results in lower-quality transfers because the signal is compressed. In either case, RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device. RCA cables connect amplifiers to all sorts of devices.
Ucoax OEM Cable Assembly RCA Cables Quality of RCA Cables Several factors affect the quality, price, and performance of RCA cables:
Materials: The connectors on RCA cables are often gold, silver, or copper. As you might expect, the gold connectors are the most expensive. They're also better than silver and copper connectors at preventing oxidation, but not as good at electrical conductivity. The silver connectors are best for electrical conductivity with the copper cables coming in a close second and the gold cables falling far behind. Other suitable materials are nickel, zinc, and tin.
Cable Length: Cable length has a negative effect on signal quality. Buy a cable that is only as long as you need it to make the connection for the best signal quality.
Shielding: A well-shielded cable delivers a better signal than one that lacks robust shielding.
The other end of the cable: If possible, match the material used in the other end of the cable to the material used in the connectors. Don't match tin with gold or silver with gold. Those combinations can cause problems because of an electrolytic reaction.
