Cables continue to provide a more reliable and straightforward way of getting your sound through your PA System. Just make sure that each cable are properly handled, regularly checked and maintained, and you can be sure that you're live gigs will be glitch free.
A snake cable is a system of cables that are organized to provide convenient stage connection between multiple sound sources and your mixer. Instead of having to lay down multiple wires for multiple mics and instruments, all you have to do is get a snake rolled out and use the solid connection that it provides. This allows for a more organized and clutter-free setup.
Portable PA Systems are affordable solutions for musicians who perform mainly at smaller venues like coffee shops, small bars and the like. These usually come with a mini mixing console, some built-in effects, a power amplifier and a built-in speaker. In line with this, many of today's powered speakers can be considered as portable PA systems, which make them modular and flexible. Many modern Keyboard Amps and Acoustic Amps are also designed to be used as small PA systems. If you perform in places where mains power isn't available then you can use a Battery Powered PA System.
These speakers project sound to you and your audience. Included here are Front of House (FOH) Speakers, Foldback or monitor speakers, Subwoofers, Powered Speakers and modern Bluetooth capable speakers. Also mentioned are speaker stands that help position speakers properly on and off the stage.
Even within communications applications, we have applications that differ widely in usage and in methods of installation. We have "outside plant" fiber optics as used in telephone networks, CATV, metropolitan networks, utilities, etc. or "premises" fiber optics as found in buildings and campuses. We have fiber on "platforms" like cars, planes and ships (and the space station.) Just like "wire" which can mean lots of different things - power, security, HVAC, CCTV, LAN or telephone - fiber optics is not all the same.
Since all these applications require different installation procedures, let's look at them in more detail.
A High-Definition Multimedia Interface cable is the modern standard for trasmitting high-definition digital video and audio. HDMI cables can carry both standard and 3D video as well as surround sound audio and internet. For this reason, most modern game consoles and televisions use HDMI to interface with computers or set-top boxes.
RCA connectors, also called phono connectors, are analog cables and have been used for years to transmit standard definition video and audio. RCA cables for home theater are usually seen in triples: a yellow video jack, and the red and white stereo audio cables.
The Sony/Phillips Digital Interface Format is used for transmitting digital audio. It can carry multiple channels and is often used in home theater systems where HDMI does not carry audio
5.1, 6.1 and others refer to speaker configurations. A 5.1 speaker system has five (5) satellite speakers and one (1) subwoofer. This is the standard method of referring to speaker configurations. For instance, a 3.3 sound system would be a strange one with three satellite speakers and three subwoofers
