Mackie SP260 Owner's Manual page 23

One side is way louder than the other!
• Are the level controls set the same for both
sides on the mixer, amplifier and processor?
• Are the gain settings the same for all left-right
pairs of inputs and outputs on the processor?
• Are the EQ settings the same for all left-right
pairs of inputs and outputs on the processor?
• Are the limiter settings the same for all left-right
pairs of outputs on the processor?
• Check the pan control on the signal source. It
may be turned too far to one side. If you're using
a stereo signal source, it may be delivering an
out-of-balance stereo signal.
• Try switching sides: Turn off the amp, swap
the speaker cables at the amp and turn the
amp back on. If the same side is still louder,
the problem is with your speaker cabling or
the loudspeakers. If the other side is louder
now, the problem is with the mixer, the amp, or
the line-level cabling.
Bad Sound
• Are the input and output connectors plugged
completely into the jacks? Make sure they are
plugged all the way in.
• Is it loud and distorted? Reduce the signal level at
the mixer, amplifier and/or processor.
• If possible, listen to the signal source with
headphones plugged into the preamp stage. If it
sounds bad there, it's not the processor.
• Have you gone a tad overboard with the gain and
EQ settings? Cut is our friend and boost should be
used wisely.
• Has the band been together long?
Factory Reset:
As a last ditch effort, you can reset the SP260 to its
factory settings.
Please keep in mind that this erases all settings,
including any passwords and presets that may
have been set. Be sure to power down any amps
and/or powered speakers before resetting the SP260.
Simply press and hold the Enter [10], ESC [11] and
Utility [12] buttons when powering up until the LCD
Display [6] shows:
Please Wait....
Memory Reset
Then you may take your fingers off the buttons.
You will know it worked when the six output
Mute LEDs [15] illuminate after the SP260 is
fully powered up.
The default password is six zeroes: 000000
