These cables use foil shields to reduce their overall diameter to a reasonable size. Because of the fragility of the foil shields in a snake cable (and because of the high cost per foot) you must take extra care in their handling. Avoid sharp bends in these cables. Also avoid placing heavy objects on a snake cable, or rolling heavy objects across them. Snake cables can be a money saver and a time saver when you are setting up a large, multimicrophone system. They also allow you to move your mixer off the stage, to a place in the audience where you can hear better! Ask your Fender dealer for help in selecting a snake for your system. Cable and Connectors For Line-Level Devices. Line-level devices normally use the same type of cable and connectors as microphones, instruments, and other low-level devices. That is, balanced line-level devices normally use XLR type connectors and unbalanced line-level devices normally use 1/ 4“ phone plug connectors. Some balanced line level devices use three-conductor, I/4" Tip/Ring/ Sleeve (TRS) connectors. Polarity is, again, unfortunately not standardized on balanced line level devices using XLR connectors. Either pin 2 or pin 3 may be the “+” pin (pin 1 will almost always be the shield or ground). Thus, you should check the polarity of any unfamiliar device you may be using. Cable and Connectors For Loudspeakers. Speaker cable carries much higher levels of electrical power than either microphone or line-level cable. For this reason, speaker cables use larger gauge wire. Typical speaker cable uses anywhere from #18 gauge wire to as large as #10 wire. #18 gauge wire is suitable only for low-power loudspeakers (like the hi-fi speakers in your home). #16 gauge wire is suitable for short runs (less than 25 feet) of low to medium power pro audio loudspeakers. #14 gauge wire is suitable for most pro audio work unless loudspeaker runs are longer than about 75 feet. In that case, #12 gauge wire should be used. For very long runs of high power speaker cable, use #10 gauge (or even #8 gauge) wire. A better way to handle long speaker runs, however, is to move the power amplifier closer to the loudspeakers and run line-level signals (in shielded cable) over the long distance. Loudspeaker connectors are another story. The most common loudspeaker connector in pro audio is the 1/4" phone plug. Unless you use very high quality phone plugs, however, they are actually not very suitable for the high current use they get in pro audio. Thus 1/4" phone plugs are only suitable for low and medium level loudspeakers (perhaps up to 300 watts or so per loudspeaker). For higher power loudspeakers, a higher current connector like a “dual banana” connector is a good choice. XLR connectors are 64 Pads and Transformers.

Perhaps the best loudspeaker connector (outside of the dual banana plug) is the new Neutrik “Speakon” connectors. These are 4 conductor and 8 conductor connectors, and are most often used for hooking up biamplified or tri-amplified sound systems, using a single connector. Some loudspeaker systems you may encounter, however, may have this style of connector. Check the speaker systems owners manual to see how to wire that particular speaker to your PX-2200. Adapters. If all audio devices used the same connector, we wouldn’t need adapters. Suffice it to say that we do need them, often! Take care in using the adapters shown here. They will, in most cases, allow you to connect one type of device to another. They do not help you maintain impedance and level compatibility! In some cases, you may need a pad, or a transformer (or even a preamplifier) along with an adapter in order to be able to connect two audio devices together. Consult your Fender dealer if you need help with these connections. Attenuator Pads. An attenuator “pad” is a resistor circuit that reduces the output level from a source device to make it "level compatible” with a load device. For example, a pad could be used to connect the output of a +4 dB limiter to the -10 dB GEQ In jack on your PX-2200 Mixer. The pads shown here are of two types: balanced and unbalanced. The balanced pads are meant for balanced microphones or for low-source impedance balanced line-level devices. In most cases, however, you will not nee...
