Frequently Asked Questions
How do I daisy chain the speakers?
oAnswer: You can daisy chain other SA-15T speakers by using one of the available ¼” or Speakon
output jacks on the primary speaker. (note: daisy chaining causes impedance to change. Make
sure your amplifier is stable based on the amount of speakers you have in a daisy chain.)
Why is there (2) speakon and (2) ¼” jacks on the back of an SA-15T speaker?
oAnswer: There are speakon and ¼” jacks to give user the option on which connection they
choose. The second connector is in case the user wants to daisy chain another speaker.
Can the SA-15T speakers be pole mounted?
oAnswer: Yes, the SA-15T speakers have a metal top hat installed on the bottom for pole
mounting. It will fit a 1 3/8” speaker pole stand.
Can I plug a Microphone or MP3 player into the connection jack on the back of the speaker?
oAnswer: No, the connection jacks on the back of the speaker are only used for powering the
speaker from an amplifier.
How do you control the bass and treble?
oAnswer: You would need to have your amplifier connected to an external mixer or EQ.
Do the SA-15T speakers have a built in crossover?
oAnswer: Yes, there is a crossover built into each SA-15T. The crossover point is 2.5K.
Can I plug the SA-15T speakers into my home stereo / theater receiver?
oAnswer: Yes, but it is not recommended. The SA-15T speakers are pro audio rated meaning they
require more power than a normal home theater speaker would require. It is recommended you
choose a pro audio amplifier with proper power for connection.
Troubleshooting
The SA-15T speaker(s) have no output sound and do not appear to be working.
oAnswer: The SA-15T speakers require a power amplifier. Check to make sure the amplifier is
powered on and is receiving power. Make sure the speaker cables are connected properly in
both speaker and 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-15T speaker(s) are making a hum/buzz sound.
oAnswer: Make sure you are using 12-16 gauge speaker cables from your power amplifier. Also,
check your amplifier and mixer for proper cables. A shorted out cable or improper shielded cable
could cause buzzing. Also, check to see if your power amplifier 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-15T speaker(s) sound Distorted or Fuzzy.
oAnswer: First, make sure the power amplifier 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.
