Connection Example 1
Connection Example 2
Standard 3-Pin XLR
Microphone Cables (Male
to Female)
This example shows how to connect two SA-15MT-PW or SA-12MT-PW speakers to a standard Mixer. This application requires
(2) XLR 3 pin male to female cables. Seismic Audio offers these cables. The model number is: SAXLX-25.
To start, take the female end of the first cable and insert it into the output jack labeled MAIN OUT LEFT on your mixing board.
Then insert the male end of the cable into the XLR input of the first or left SA speaker. Repeat these steps using the other
cable and insert the female end into the MAIN OUT RIGHT on the mixing board, followed by inserting the male end of the
cable to the second or right SA speaker.

Daisy Chaining Signal from one SA Amp to another
SA Amp
This example shows how to connect two SA-15MT-PW SA-12MT-PW speakers to a standard Mixer using one MAIN
OUT jack on your mixer. By choosing this method, it will free up one main out jack on the mixing board and allow
the PWS speakers to be Daisy Chained. This application requires (2) XLR 3 pin male to female cables. Seismic Audio
offers these cables. The model number is: SAXLX-25.
To start, take the female end of the first cable and insert it into the output jack labeled MAIN OUT LEFT on your
mixing board. Then insert the male end of the cable into the XLR input of the first or left SA speaker. Second,
insert the female end of the second XLR cable into the XLR output jack of the first SA. Lastly, insert male end of the
XLR cable into the XLR input jack on the second SA speaker.

Connection Example 3
Example cable:
Insert a 1/8” cable into the
MP3 line input on the SA
speaker and plug the other end
into any device that accepts
the 1/8” headphone
connection. See Seismic Audio

Frequently Asked Questions
How do I daisy chain other powered or active speakers?
oAnswer: You can daisy chain other powered speakers by using the XLR inputs and XLR outputs on
the SA-MT speakers.
Why is my second SA-MT speaker not working? I have one SA-MT speaker connected to my mixer with a
¼” cable and I have an XLR cable connected from the SA-MT speaker 1 XLR output to the XLR Input of SA-
MT speaker 2.
oAnswer: Daisy chaining the signal to a second SA-MT speaker only works when you are using the
XLR jacks only for input and output.
What is the difference between the gain knob and volume knob? They seem to both do the same thing.
oAnswer: The gain knob controls the level or strength of signal before the signal is amplified. The
gain setting determines how clean or dirty your sound is. The Volume knob controls the power
amp and the strength of the sound.
When I plug a microphone into the input jack, I can barely hear it, why is that?
oAnswer: The input jacks on the SA-MT speakers are not meant for line level microphones to be
connected. The signal from the microphone will not be hot enough. If you need to run a
microphone, it is recommended add a small sound board or mixer to your SA-MT speakers.
Will the XLR jacks pass through a signal if the speaker is turned off?
oAnswer: Yes, The XLR jacks do act as a pass through.
Can you use these speakers with an external power amplifier?
oAnswer: No, hooking an external power amplifier to the speakers will damage both the built in
amplifier and speakers.
Troubleshooting
The SA-MT speaker(s) have no output sound and do not appear to be working.
oAnswer: The SA-MT speakers have a built in amplifier. Check to make sure the amplifier is
powered on and is receiving power. Make sure the red voltage switch is selected 115v. Make
sure the speaker cables are connected properly into the amp. Make sure cables are not shorted
out. If the speakers are new out of the box… It is possible that during shipping a fuse could have
fallen out of the crossover or an internal wire slipped off the speaker terminal. For more help or
troubleshooting, call the Seismic Tech Hotline at 1-877-347-6423 ext 2.
The SA-MT speaker(s) are making a hum/buzz sound.
oAnswer: Make sure you are using shielded cables. Also, check your mixer for proper cables. A
shorted out cable or improper shielded cable could cause buzzing. Also, check to see if your SA-
MT speaker is connected to a dedicated electrical circuit. Humming noise often can come from
electrical current feeding through the lines. It is recommended to use a power conditioner for all
of your amplifiers and pro audio gear.
The SA-MT speaker(s) sound Distorted or Fuzzy.
oAnswer: First, make sure the built in amplifier on the SA-MT speaker and/or mixer is not clipping
or being overdriven. Check the volume levels on your input devices and mixer. It is possible that
your amplifier is either under powering or over powering causing a distorted signal. For more
help or troubleshooting, call the Seismic Tech Hotline at 1-877-347-6423 ext 2.
