I’m confused

Alto TX15s clipping

We have 4x Alto TX15 speakers with 2x 500 EV Subwoofers soon. In our current setup, 4 Alto TX15's are working together for the vocals only so far, 4-6 vocals.

Now the problem is that the speakers lits up the Clip Red signal on its back during loud parts of a song, but rarely lits up red during a MP3 played at very high volume, I could say louder than the vocals that causes it to clip and with all the bass it is throwing. I am not quite sure yet how to solve the issue of these 4 TX15's clipping at some points (seconds and split seconds) for running vocals and not clipping through MP3 playbacks at high volume.

We are planning to run a whole band through it with drums, lead guitar, rhythm guitar, keyboard, and those vocals. I'm quite afraid this could easily damage the speakers if left unsolved or optimised, I hope someone could help out.

my setup:
Alto Live 2404 Pro Mixer
DBX 2/3 way crossover
Graphic EQ (where Alto TX15's are connected)
Electro Voice 18" Passive Subwoofers
Subwoofer Amplifier
Fender 300 Passport Pro (for stage monitors only)

  • Hello Bryan,

    Sorry to hear about your troubles. This sounds like a setup a issue. On the TX15 speakers, position your gain on the speaker to the 12 o'clock position. Position your subs gain to the 12 o'clock position. Do you still have this problem?

  • I would try that, at this moment the speakers are set all the way up (FULL) on its gain, why I did this because the speakers are mounted up high in the ceiling.

    What do you mean by the Subs gain?

    how my setup is wired (from left to right)

    • I don't recommend daisy chaining your speakers with this equalizer. This is part of your problem. Each channel should be dedicated to each speaker.
    • I don't think you got me right. GEQ CH1 output is wired to Alto TX15, another Alto TX15 is wired from the back of the first TX15 whic is labeled "Link". Technically they will receive the same signal and volume from the GEQ's CH1.

      Same setup is done to GEQ's CH2.

  • when the Signal Limit led blinks:

    1) is it because the signal that the loudspeaker receives is distorted/clipping?

    OR

    2) is it because the loudspeaker is overwhelmed by the signal sent to it? That it is having a hard time reproducing the sound to its drivers?

    These are two different scenarios, I don't know how the signal limit led is actually programmed/wired/setup so your clarification would be a great help to troubleshoot more to this.

    If its the number 1 reason, how / what should you recommend to fix it? while maintaining high volume output without clips.

    • Sure I can, but that will decrease the volume.

      Question: How do I know if the Alto TX15's are already maxing out? What should I be watching for.
    • Hi Bryan,

      Please see my post above. The Signal Limit LED will illuminate when the audio signal being sent to the loudspeaker is clipping or distorting. If this LED illuminates frequently or steadily, reduce the volume of your audio source (your mixer in this case).
