•  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. 

•  Consult the dealer or an experienced radio/TV technician for help. 

 

Thank you for purchasing a Lab.gruppen power amplifier. This manual contains important information 
on operating your amplifier correctly and safely. Please take some time and read this manual to 
familiarize you with the advanced features of this amplifier. 

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, always use the original packing. 
 

1. Carry/protection handle 
Both handles can be used to carry the amplifier; they also act as protection for the front panel. In 
permanent installations, or where rack front covers are too shallow they may be removed by unscrewing 
the retaining bolts behind the front panel. 
 
2. Input level attenuators 
These controls are used to alter the signal level entering the amplifier. They are calibrated in dB to assist 
the setup of active loudspeaker systems, or to cut down unwanted noise from the input signal. (See page 

) 

 
3. Over temperature protect indicator 
This indicator illuminates if the amplifier is going to operate above its maximum operating temperature 
(90°

°

C). The indicator first comes on as a warning to either turn down the input level or check the 

cooling arrangements. Beyond the maximum temperature the amplifier will mute the input signal. Once 
the cooling fans have brought the output heat sinks back to normal operating temperature the input 
signal is un-muted. 
 
4. Protect indicator (VHF and short circuit) 
This indicator illuminates if signals above 12 kHz are continuously present at full power at the output 
terminals or if short circuit protection is activated. If this occurs the input signal is muted, and the process 
cycles until the VHF signal is no longer present or the short is removed. (See page
