Lab.gruppen LAB 1600 - Manual (Page 2)

Unpacking
Carefully open the shipping carton and check for
any noticeable damage. Every LAB.GRUPPEN
amplifier is tested and inspected before leaving the
factory and should arrive in perfect condition. If
found to be damaged, notify the shipping company
immediately. Only the consignee may institute a
claim with the carrier, for damage incurred during
shipping. Be sure to save the carton and packing
materials for the carrier's inspection.
It is also advisable, to save the carton and packing
material, even if the amplifier is undamaged.
Should you ever need to ship the amplifier, use the
original packing.
Warnings
Read this before you are operating your amplifier:
• Do not use this amplifier if the power cord is
broken or frayed.
• Always operate the unit with the chassis
ground wire connected to the electrical safety
earth.
• Do not parallel or series connect an amplifier
output, with any other amplifier output. Do not
connect the amplifier output to any other
voltage source, such as battery, mains source,
or power supply, regardless of whether the
amplifier is turned on or off.
• Do not run the output of any amplifier back
into another channel's input.
• Do not block the air intake or exhaust ports.
Do not operate the amplifier near heat
producing devices such as radiators, stoves etc.
• Do not spill water or other liquids into or on
the unit. Do not operate the amplifier if
suspected or standing in liquid.
• Do not remove top or bottom covers. Removal
of the cover will expose hazardous voltages.
There is no serviceable parts inside and
removal may void warranty.
•
Keep this manual for future reference.
User responsibility
1. Speaker damage
Your amplifier is very powerful and can be
potentially dangerous to both loudspeakers and
humans alike. Many loudspeakers can be easily
damaged or destroyed by overpowering, especially
with the high power available from a bridged
amplifier. Always check the speakers continuous
and peak power capabilities.
Even if the gain is reduced by using the
amplifier's front panel attenuator, it is still possible
to reach full output power, if the input signal level
is high enough.
2. Speaker output hazard
Power amplifiers are capable of producing
hazardous output voltages. To avoid electrical
shock, do not touch any exposed speaker wiring,
while the amplifier is operating. See page 6 about
outputs for proper connection of speakers.
3. Radio interference
This product has been tested, and complies with the
limits for the European Electro Magnetic
Compatibility (EMC) directive. These limits are
designed to provide reasonable protection against
harmful interference between electrical equipment.
This product uses radio frequency energy, and if
not used or installed in accordance with the
operating instructions, it may cause interference to
other equipment, such as radio receivers. However,
there is no guarantee for no interference even if the
amplifier is EMC approved.
If the amplifier cause interference, which can be
easily determined by turning the amplifier on and
off, the user can correct the interference by one or
more of the following steps:
1. Increase the proximity between the equipment.
2. Connect the AC cord to an outlet on a different
circuit from that to which the affected unit is
connected.
3. If a radio receiver is interfered (normally
amplitude modulation); reorient the antenna.
4. Check if the affected unit complies with the
EMC limits for immunity, (CE-labelled).
If not, address the problem with the
manufacturer or supplier. All electrical products
sold in the EC must be approved for immunity
against electromagnetic fields, high voltage flashes,
and radio interference.
