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.

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.
