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.
