Balanced and Unbalanced Cables Defined
Balanced electrical signals travel along 3 wires: a positive, a negative, and a ground. The positive and negative carry the same signal, just in opposite polarity to one another. Noises that may be picked up in the cable will usually be common to each leg. As long as the destination is balanced, the receiving device will flip the signal, bringing them back into polarity. This eliminates the noise by causing it to be out of phase. This is commonly referred to as Common Mode Rejection and is the primary reason balanced cables are best for long cable runs. TRS and XLR cables are made to send balanced audio from one balanced device to another balanced device.
Unbalanced cables are much simpler than balanced. However, they can easily fall victim to noise issues. Unbalanced lines should be used in shorter lengths, ideally 25 foot and under. This will go a long way in reducing any noise that could be carried with the signal into your gear. Instruments, like guitars. and their users vow they can tell a difference in the tone the longer the cable gets.
There are six primary cable connector types in the world of Pro Audio. XLR and TRS for balanced connections; Speakon, TS, RCA, and Banana Plugs for unbalanced connections. Here is a brief overview of each:
An XLR connector has positive, negative, and ground connections. They are primarily used for balanced line-level signals and for microphone signals. These are commonly used for connecting mics to mixers and for hooking up various outputs to powered speakers.
TRS is also referred to as Tip, Ring, Sleeve. It has the same appearance as your standard 1/4″ and 1/8″ plugs. The difference is that it has an extra ring on the plug. TRS cables are two conductor plus a ground. Commonly used to connect balanced equipment and for running left and right mono signals to stereo headphones. These will also be located on Y cables for use in mixer insert jacks when the signal is sent out in one wire and comes back thru another wire.
Speakon connectors are used to carry amplified signals. They are most commonly used to connect power amplifiers to PA speakers, Monitors, and Subwoofers in studio or on stage. They have a unique locking feature that tend to make them a more attractive option than the 1/4″ TS connection. It should be noted that is recommended to never use an instrument cable to connect an amplifier to a speaker.
TS is also referred to as Tip, Sleeve. It is the universal name for specific type of 1/8″ or 1/4″ connector meant for a two conductor unbalanced operation. Only one insulator ring separates the tip and the sleeve. The tip carries the signal and the sleeve is where the ground is connected. These cables are best used as guitar or line level instrument cables.
Banana plugs are an electrical conductor made to connect audio wires (speaker wires) to the binding posts on the back of power amplifiers, speakers, or simply to a banana jack. These banana jacks are most often found at the end of a binding post receptacle on power amplifiers and some speakers.
RCA is the term most commonly used when referring to phono connectors used to connect consumer stereo gear. You will usually see CD outputs or inputs using these RCA connections. RCA connectors are also used in the digital audio world for connections such as S/PDIF, but are still a staple in the pro audio world.

We also have launched several new stands to accomodate iPhones, iPads, and other tablet and mobile devices. These can be found on our website www.seismicaudiospeakers.com. First, we would like to introduce you to a couple of the new items!
If you are looking for big cabinet sound in a small cabinet, look no further! You have found it! This cabinet gives you BIG sound in a small package! The Rift 46G cabinet delivers the sound usually associated with a much larger cabinet, without the weight of a 412 guitar or 410 bass rig. This cabinet is perfect for practicing, small gigs, and recording purposes. Here is the kicker….The Rift 46G can be used as a bass cab as well! That is right! We said it and put it in print! The Rift 46G is awesome for low volume applications as well. It delivers for both! Equipped With four Quake 6” speakers, the SA-Rift_46G can hang with bass cabs much larger while still giving you plenty of full range articulation and attack. At 250 Watts RMS, its smaller profile makes it an excellent cab for the gigging musician who doesn’t have the room for a bigger cab but doesn’t want to sacrifice their sound for the real estate.
Snake Cables on a Reel are designed to make life a little easier in any venue. This snake is road ready with 22 gauge wires and ready for everyday gigs. Reels make tear down and set up a lot smoother and faster when going from gig to gig or club to club. XLR Connectors on the returns make this snake cable fit right in with professional power amps and mixing consoles without the need for converters or couplers. Performance and convenience all rolled into one!

Our Aftershock 18 is a very versatile piece of Pro Audio gear! We take calls everyday from customers wanting to know what is the best way to connect this subwoofer to their existing gear. The Aftershock 18 Powered Subwoofer is unique in its ability to power other passive speakers as well as act alone if you are only wanting to utilize the sub functionality of it. Here is a quick “how to” on how to connect your Aftershock 18:
The first thing you are going to need to do is plug it into a power source! Haha!
If you are running active or powered tops, such as our PWS series, and only want to use the sub functionality of the Aftershock 18, what you will need to do is come out of your mixer into the powered tops. Using a standard XLR cable, you should then come out of your powered tops into the #4 output on the back of the Aftershock. This will allow you to utitlize only the sub function of the Aftershock and beat the house down with bass!
The Aftershock also has a satellite function on it to power other passive speakers. To utilize this satellite function, you should come out of your mixer to the #3 input on the back of the Aftershock. The only thing you have to do from here is connect your passive tops to the satellite output using Speakon cables. Now you are powering your tops from your Aftershock!
Tech Note! – You should never exceed 130 on your tone controls, ever! Also, always be aware of your clip light situation. Avoid clipping at all costs by controlling your low pass filter and volume control functions.
This is just a quick how to on connecting your Aftershock 18. As always, if you are not sure or have any questions, please give the Seismic Audio Tech Department a call at 901-363-6030. We will be happy to assist you in any way.

Can and how do I daisy chain these speakers together? It is a question we get more times than you would think!
Here is a quick guide for connecting PASSIVE speakers together. Most Seismic Audio Speaker Cabinets have two jacks on them. One jack is used for connecting the speaker to the amplifier and the other can be used to connect a second speaker off of the first. This process is commonly referred to as “daisy-chaining”. Simply taking one cable and connecting your passive speaker(SA-15T) to the amp, then taking another cable to power your second passive speaker(SA-15T).
When you daisy chain speakers, this is what happens:
If you connect two 8 ohm cabinets together, it cuts the ohm load in half. Therefore, two 8 ohm cabinets hooked together will give you a 4 ohm load. If you connect four 8 ohm cabinets together, it will result in a total of a 2 ohm load.
Please NOTE that it is not recommended to daisy chain two cabinets with different ohm loads. EXAMPLE: Do not connect a 4 ohm cabinet with an 8 ohm cabinet. It will result in an uneven power distribution between the two cabinets.
Be sure to check the minimum impedance rating of your amplifier before daisy chaining your speakers. Dropping below the recommended ohm load on your amplifier can result in a lot of damage to the amp and or the speakers.
This is a simple guide to daisy chaining your PASSIVE speakers. As always, if you have any questions concerning the correct configuration of your system, please call the Seismic Audio Techs and we will be happy to talk you through it!
