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.

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.

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.

Our PWS series PA Speakers are an ideal way to plug and play music from your iPod or other MP3 device. This is a great way to share your favorite playlists with your friends at a party, bar-b-que, or any other gathering of people! There are a few different ways to connect these devices to one another.
They are as follows:
Option 1 – This one is the best solution in our opinion. You should have access to or purchase a mixer with Left and Right, XLR out connections. These can usually be found for a very reasonable price. Hook the iPod or MP3 to the CD in connections via a 1/8″ to RCA stereo cable. Then, wiring the PWS speakers, one to the left output and the other to the right using standard mic cables. This configuration should provide the best possible sound. This is due to the fact the mixer takes into consideration all of the pertinent technical aspects of such an arrangement, to provide a good sound with a mix of audio classed products.
Option 2 – The second solution would be to connect the iPod or MP3 output with a 1/8″ to 1/4″ TS cable. Next, connect the 1/4″ TS cable to each of your PWS speakers.
Option 3 – If you have only a single PWS speaker, the connection is very simple. You can simply connect the iPod or MP3 output with a 1/8″ cable to the 1/8″ input on the PWS speaker! Viola! Instantly, your favorite tracks are playing out of the speaker!
As always, if you have any questions concerning the setup of your audio equipment, the Seismic Audio Tech Department will be glad to assist you. Give us a call at 901-363-6030.

The following is a question we received from one of our customers:
“A few months ago, I purchased your PWS-15 speakers — and love ‘em — they sound great! This past weekend, I was reminded to shoot you guys an email to inquire about something. I noticed they gets hot around the back control panel (the grill area). Is this normal? ”
Occasionally, we get this question. It is usually a novice or beginner in the Pro Audio world. It is a valid question and important to know why this is happening. The most common solution to this issue is as follows:
Usually that is an indication that, either the input gain is turned up a little too much, and / or the some of the tone controls are turned up a little too high. Ideally, the input gain should be close to the 12 o’clock position. Also the tone controls should not exceed the 2 o’clock position. In the event that you would like a particular frequency range boosted over another, the same results can be obtained by turning down the tone controls of the unwanted frequencies until the tone you are looking for is achieved.
We understand that little issues like this can be frustrating. In any event, we always welcome and encourage you to call the Seismic Audio Tech Department at 901-363-6030 Extension 1. Those guys are experienced in all audio events and will be happy to help you in whatever way you need.

“What amp do I need to power these speakers?” This is another frequently asked question we receive when customers are buying PA speakers. It can be a complicated answer. The amp must have the correct amount of power and the correct features for your PA system. Here is a guide that may help in your endeavor to find the correct power amp.
As a general rule, you should select a power amp that has a power output of 1.5 RMS that of the speaker’s RMS rating. For example, if you have an 8 ohm speaker with an RMS rating of 400 watts, then you would need an amplifier that can produce 600 watts RMS into an 8 ohm load. In the event you have a stereo pair of speakers, you would need an amp that is can produce 600 watts RMS per channel into 8 ohms.
Seismic Audio PA Speakers are high quality and can take brief peaks greater than its power rating if the amps can transfer those temporary peaks without distortion. Therefore, we recommend taking advantage of an amp with extra headroom (1.5 X the power rating). This will guarantee that only undistorted power reaches your speakers. Some amps are made to accommodate additional headroom. These particular amps cleanly reproduce those brief outputs that exceed the power rating. If you decide to go with one of these amps, just be sure that it has an output rating, at least 1.5 x the RMS rating of the speaker.
Choosing an amp with the correct power rating is essential to high quality sound. You should never run an amp when the power rating is less than the RMS of a speaker as this could cause the amp to start clipping. The speakers in a sound systems can be damaged by running an amp without the proper power rating. It will usually result in constant distortion and can even blow your speakers.
We realize that all of this information can be overwhelming. If you have any questions or concerns, you should always call the Seismic Audio Technical Department at 901-363-6030 x1. We will gladly assist you in your decision of which power amp best fits your needs.

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!
