Mackie d.4 Pro Owner's Manual page 21

Bad Sound
• Is the input connector plugged completely into the
jack?
• Is it loud and distorted? Make sure the input level
[29] control is set correctly. Reduce the signal level
on the input source if possible.
• If possible, listen to the signal with headphones
plugged into the input source device. If it sounds
bad there, it's not the d.4 Pro causing the problem.
• If you are using a turntable with a phono-level
output, and the sound is low and distorted, check
that the line/phono [5] switch is set to phono. Note
that the phono section requires your cartridge to be
a moving magnet type. It may be too low to amplify
the low levels of a moving coil type.
Noise/Hum
• Turn down the aux return [41] knob. If the noise
disappears, it's coming from whatever is plugged
into the aux returns [9].
• Check that your turntable's audio ground wire is
connected to the phono ground [6] terminals.
• Turn down each channel, one by one. If the noise
disappears, it's coming from whatever is plugged
into that channel. Check your whatever.
• Check the signal cables between the input sources
and the d.4 Pro. Disconnect them one by one. When
the noise goes away, you'll know which input source
is causing the problem.
• It often helps to plug all the audio equipment
into the same AC circuit so they share a common
ground.

Recording to FireWire
• If you are recording vinyl music to your computer,
and the level seems low, set the FW out switch
[7] in the out position, so the FireWire outputs
come after the level and EQ sections. This will give
you the chance to boost the levels with the level
controls [29]. Set the source select switch [30] to
line/phono, and the line/phono switch [5] to phono.
• If you are using timecode vinyl or timecode CD,
then press in the FW out switch, so the Firewire
outputs come directly after the phono section. In
this way, you can have the timecode flowing to your
computer, and use the source selector switch to
play the computer output in that same program
channel.
