Why is my Alto TMX 80 DFX signal distorted and very loud?
The signal from your Alto Music Mixer may sound distorted and very loud, with the LIMIT light frequently on, because the input signal is too high, exceeding the speaker's capacity. To resolve this, try reducing the output level from the source, lowering the level controls on the speaker, or testing with an alternative set of speakers.
Why is there so much hiss in the sound from my Alto TMX 80 DFX Music Mixer?
Excessive hiss in the sound from your Alto Music Mixer, even with low control settings, is likely due to an improper gain structure. Ensure the MIC/LINE switch is in the LINE (disengaged) position. Also, reduce the level settings at the speaker, review your mixer's manual, and adjust controls as needed, paying attention to input sensitivity (gain), channel faders, and master faders.
What to do if I hear hum or buzz when moving the mixer level controls of my Alto Music Mixer?
If the hum or buzz changes when you move the level controls on your Alto Music Mixer, it could be due to an improper A/C ground, faulty equipment connected to the mixer input, or a faulty cable between the source equipment and the mixer. Disconnect or mute channels one at a time to isolate the problem. Try substituting a known good cable for the suspected faulty one.
