SAFETY INSTRUCTIONS:
CAUTION
The lightning flash with arrowhead symbol within the equilateral triangle is
intended to alert the use or the presence of un-insulated "dangerous voltage"
within the product's enclosure that may be of sufficient magnitude to
constitute a risk of electric shock.
The exclamation point within the equilateral triangle is intended to alert the
user to the presence of important operation and maintenance (servicing)
instructions in the literature accompanying this appliance.
To prevent fire or shock hazard, do not expose this appliance to rain or moisture. Do not
place metal objects or spill liquid inside the turntable. Electric shock or malfunction may
result.
SOME IMPORTANT INSTRUCTIONS:
• Always install this appliance in a well vented place. Avoid presence of heat sources.
Avoid places that are dusty and humid.
• Don't cover any ventilation openings as this may result in overheating.
• Keep this booklet in a safe place for future consultation. If you sell the fixture, be sure to
add this user manual.
• To prevent fire or shock hazard, do not expose this appliance to rain or moisture.
• In order to prevent electric shock, do not open the enclosure. If a problem occurs,
contact your dealer.
• Do not place metal objects or spill liquid inside the unit. Electric shock or malfunction

possible.
CLEANING THE UNIT:
Clean by wiping with a cloth slightly dipped with water. Avoid getting water inside the unit.
Do not use volatile liquids such as benzene or thinner which will damage the unit.
Clean the ventilation holes regularly with a vacuum cleaner. This increases the cooling
capacity of the amplifier fans and helps preventing temperature overheat.
CONNECTIONS
Be sure to turn off the unit before you make changes to the wiring. For the signal inputs
we recommend using the XLR-connections. Use good quality signal cables to ensure
excellent audio quality. For example use JB cables with order codes: 7-0061 (XLR/XLR
L=1m) or 7-0063 (XLR/XLR L=5m). For the speakers we suggest using the Speakon®
compatible outputs. Suitable cables are for example JB order codes: 2-0505 (L=5m) or 2-
0510 (L=10m).
