properly and do not have a muted channel.
• Check speaker wire connections to the silent channel and to
the corresponding speaker and make sure thay are solid.

on the mixing console.
• Check if all signal levels on the signal processor(s) have been
set to the correct levels.
• Ensure input signal to the amplifier is not higher than the
maximum allowed input level.

that they are not electrically shorting out.
