| 3ft High-quality Coaxial Audio/Video RCA CL2 Rated Cable M/M RG6U 75ohm Gold connector (for S/PDIF, Digital Coax, Subwoofer & Composite Video) |
|Question: Can I use this cable to transmit composite video? |
|Answer: Yes. |
|Question: How can this one cable be effective for use with digital audio, LFE and composite video? |
|Answer: It is not uncommon for the CE industry to base a signal transmission standard on a pre-existing cable format. In fact, it would be very inefficient to make a new type of cable for every new type of signal (even though it sometimes seems like they do it anyway). In this case, all three of these signal types were based on signal transmission through 75 ohm coaxial cable terminated with RCA connectors. In fact, any signal transmission standard that utilized 75ohm coax cable with RCA connectors can use these cables. |
|Question: Isn''t it better to use dedicated cables for subwoofer connection? |
|Answer: What are often labeled Subwoofer cable are often a result of Marketing Spin and/or a little Consumer Electronics Voodoo. |
If the cables are a result of pure spin, then the cables are exactly the same and there''s no reason to pay more for a cable that is specifically labeled, "Subwoofer Cables."
If the cables really are "Tuned" to more effectively carry only the low frequency signals, then that''s probably a lot worse. Most high end powered subwoofer manufacturers will tell you that they put a lot of development time into matching the cabinet design, drivers, amp and crossover network in order to tune the subwoofer and give it the right voice. This tuning is based on the fact that the inputs of the sub will receive a full frequency signal that the crossover will filter to provide the appropriate signal for the amp to amplify. But if the cable is pre-filtering the signal then it is in fact coloring the signal and causing the crossover to filter out of tune. Or that is, the sound would not be as rich and full as it would be if the components of the sub were allowed to do its job with a full range signal from a proper cable.
|Question: What''s the difference between RG59 and RG6? |
|Answer: RG59 and RG6 stands for Radio Guide. It''s a standardization form for coax cables and specifies things such as impedance (75 ohms in this case) and wire gauge. The RG59 uses a 22AWG (American Wire Gauge) center wire and the RG6 uses a 18AWG wire. That means that the RG6 is a thicker cable than the RG59 since lower AWG''s denote a thicker wire. Thicker gauge wires are ideal for longer cable runs. |
Our RG6 premium cables also feature more robust RCA connectors and are certified for in-wall use.
|Question: Are the connectors gold plated? What does gold plating do? |
|Answer: Yes, they are. Gold plating provides resistance against corrosion that would otherwise impede signal transfer and could damage connections on equipment. |
|Question: Are these cables rated for in-wall use? What is CL2? |
|Answer: Yes, they are. CL2 means they have been certified by Underwriters Laboratories for in-wall use. It means that these cables have a slow burning outer jacket, should meet most fire codes. |
The CL2 rating does not affect the appearance or performance of the cables. They can be used in or out of wall.
