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.

It is amazing what hard work, patience, and the genuine desire to treat customers the way we want to be treated will result in! Just like the song from the TV show “The Jeffersons” used to say…looks like we are “Movin On Up”!! As you all know, we sell our products on Amazon.com. It helped us to get where we are today. We are in constant contact with our rep from Amazon, giving and receiving feedback and always looking for ways to improve through Amazon Services.
We received a call from them yesterday and they gave us a link to go to. What we found on the other end of the link was both humbling and exciting for us at the same time. Amazon decided to feature us as one of their Seller Success Stories. We were floored. We have always strived to grow the business. I guess you are never really prepared for the day you finally get world-wide recognition from Amazon. Here is a link to the story: http://www.amazonservices.com/content/case-studies-seismic-audio.htm?ld=AS

We are just regular guys trying to make good on our business model of providing musicians the most cost effective and high quality Pro Audio products on the market today! We believe that all musicians should sound their best, without breaking the bank to do so!

One thing we have always taken a lot of pride in is our dedication to our customers. We have never wanted to be just another corporate entity that treats their customers like a number. If it were not for you guys, we would not be here, period. It doesn’t matter if it means staying on the phone with you to ensure you get exactly what you are looking for, or our guarantee that we will be here to answer any tech questions you have. Many of you know us by name and have built relationships with us over the years. We would like to return that favor by allowing you to get to know us more personally and how we came to be in the pro audio and music industries. We are not all musicians. but if you get us in our cars or in the shower, we are all Rock Stars at heart. Allow us to introduce ourselves…the guys behind Seismic Audio.

I have often been asked about my relationship with music and the speaker industry. My usual response is that it was by chance. I enjoy music, but the other guys around here are the one’s who have all the passion for music. The next question is usually that I must share the passion on some level, otherwise why would I work in an industry that I am not passionate about. Honestly, I am still shocked that I wound up here because I previously worked in the food industry for 16 years. Then, I lost my job. It is funny, you see all the unemployment statistics in the newspaper and news, and you don’t think it is ever going to be you. Suddenly, there I was. Unemployed, wife, and two kids at home. It was scary. Wondering what you are going to do and how big of a step down I would have to take.
My friend, Steve called me out of the blue with what I thought was a crazy idea. He offered me a job on a trial basis. He then explained to me the entire history of Seismic Audio and the direction it was going. Details of how much the company had grown and the things he had in mind going forward. I thought it was crazy. The idea of him being willing to bring in someone who knew essentially nothing about Pro Audio.
It has been an amazing experience, It has been like a dream. And it came at a time when I desperately needed a dream…so I guess you could say that music saved my life.

We are always trying to keep you guys, our fans and friends, in the loop about everything that develops here at Seismic. Unfortunately, we do not always reach as many of you as we would like. Therefore, we plan to start doing a much better job of managing our blog and dubbing it “The Seismic Audio Experience“. We know you guys are busy and don’t have time to search the internet up and down to find the info you are looking for. We will try and create a clear link to it on our homepage to ensure you guys are always in the loop. Since it has been so long since we have posted, let us catch you up on all the exciting things happening at Seismic Audio!

Also, just in time for the holidays, we are rolling out the Seismic Audio Gift Certificate! It is the perfect gift idea for the musician in your life! We know how hard it can be to choose the right speaker, cable, or accessory when buying for someone. It is ideal for Christmas, birthdays, or for one of those just because occasions. You can select the amount you want the card to be good for and present it to your musician to redeem it on the Seismic Audio product of their choosing. Get one today and never have to worry again whether or not you have purchased that item they really want!
Several new products have been introduced over the last month or so. We have new Guitar Cabs, 150 foot Snake Cables, Snake Cables on a Reel, Colored Mic Screens, several new cables, and an entire line of 1/8″ and mobile type cables. 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!
