Do not use coaxial cable like
a guitar cord to make speaker
connections. They are not
designed to handle the high
currents produced by a power
amplifier and can overheat.
As the distance between the amplifier and
speakers increases, the thickness of the wire
should also increase. Speaker wire has resistance,
and when electricity passes through a resistor,
power is lost. The thicker the wire, the less the re-
sistance it offers, and the more power actually gets
to the speaker.
1/4".TS.Phone.Plugs.and.Jacks
“TS” stands for Tip-Sleeve, the two connec-
tions available on a mono 1/" phone jack or plug.
They are used for unbalanced signals and speaker
connections.

NL4-Type.Plugs.and.Jacks
This connector is compatible with the popular
Neutrik® Speakon® -pole plugs. These con-
nectors are designed to handle the higher currents
produced by amplifiers, and have a locking fea-
ture to prevent accidental disconnections. Simply
line up the tabs on the plug with the jack on the
C00z, push it in, and rotate it 1/ turn to the
right to lock it in place.

CARE.AND.MAINTENANCE
Your Mackie loudspeakers will provide many
years of reliable service if you follow these simple
guidelines:
• Avoid exposing the loudspeakers to moisture.
If they are set up outdoors, be sure they are
under cover if you expect rain.
• Avoid exposure to extreme cold (below freez-
ing temperatures). If you must operate the
loudspeakers in a cold environment, warm up
the voice coils slowly by sending a low-level
signal through them for about 15 minutes
prior to high-power operation.
• Use a slightly damp cloth with a mild soap
solution to clean the cabinets. Avoid getting
moisture into any of the openings of the cab-
inet, particularly where the drivers are located.
CONNECTIONS
The C00z has 1/" TS and Speakon™ style IN-
PUT and THRU connectors. The connectors are
wired in parallel, so use only one of the input connec-
tors (either 1/" TS or Speakon-style).
INPUT THRU PARALLEL
Normally, you would use only one THRU
connector, but it is possible to use both THRU
connectors. Keep in mind that all the speakers are
connected in parallel through these connectors, so
you want to be sure not to go below the minimum
impedance requirement for your amplifier.
The C00z has a nominal impedance of 8 ohms.
Two C00zs in parallel equals  ohms.
Three C00zs in parallel equals .7 ohms.
Four C00zs in parallel equals  ohms.
Use heavy gauge, stranded wire for connecting a
speaker to the output of a power amplifier.
