8. Always operate the unit with the chassis ground wire connected to the electrical safety earth. Do not defeat the safety purpose of a grounding-type plug. A grounding type plug has two pins and a third grounding prong. The third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. -

QKN= råé~ÅâáåÖ= 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. -
Page 6: Rear Panel
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 15) 5. -
Page 7: Gain Switch
Three of the switches in the DIP switch selects the maximum gain of the channel to be either 20, 23, 26, 29, 32, 35, 38 or 41dB. (See page 6) 9. AC power cable R= ob^o=m^kbi=cb^qrobp= Before turning the amplifier on please read the following sections to make sure that the unit is set up properly for your specific application. -
Page 8: Options
RKNKP= léíáçåë= As the DIP switch is recessed, one may put a sticker across the bay to prevent from unauthorized changes. Another option is to completely remove the DIP switch. This should be done by authorized service personnel only! It corresponds to all switches set to “off”, i.e. 32dB gain and stereo mode. RKO= iáåâ=ëïáíÅÜ= The Link switch located on the rear panel (in the centre of the DIP switch) is for changing the operation mode of the amplifier (see next section 5.3). - Page 9 same position. We recommend that you set them to the 0dB (full) position. Connect the speaker as shown. Always use Channel A’s output connector. RKPKR= _êáÇÖÉ=ãçåç=ãçÇÉ=ÑÉ~íìêÉë= Bridged mono mode combines the power of both channels into one speaker. This results in twice the voltage swing, four times the peak power and just less than three times the full power of a single channel.

Page 10: The Solution
If you reduce the amp’s output power by choosing lower MLS values, you only reduce the maximum output voltage. In fact, you will get more current headroom for low impedance loads. The amp runs at higher efficiency, and the risk for going into thermal protection is significantly lower. -
Page 11: Installation
The amplifier uses a forced air cooling system to maintain a low and even operating temperature. All fan-cooled Lab.gruppen amplifiers have front to rear airflow. There are several reasons for this, one being that there is usually cooler air outside the rack than inside, and therefore the amplifiers can run at higher continuous power levels without thermal problems. -
Page 12: Grounding
SKR= dêçìåÇáåÖ= There is no ground lift switch or terminal on this amplifier. The signal ground is always floating via a resistor to chassis, and the grounding system is automatic. If a potential above 0.6V is presents in between signal ground and chassis ground, a short circuit is introduced between the two, thereby enabling electrical protection. -

Page 14: Balanced Inputs
They are wired in the following manner: The right jack, Channel A, provides both channel A and B outputs, so it is useful for bridge and bi-amp operation (see bridge mono operation on page 7). The left Speakon, Channel B, carries only the channel B output. -

U= lmbo^qflk= UKN= léÉê~íáçå=éêÉÅ~ìíáçåë= • Make sure that the power switch is set to “off” before connecting any input or output, or operating the switches on the rear panel. See page • Make sure that the AC mains voltage is correct, and the same as the one printed on the rear panel of the amplifier. -
Page 16: Protection Features
V= molqb`qflk=cb^qrobp= Each Lab.gruppen amplifier has many advanced protection features. Should a fault condition arise they are protecting both, the amplifier and the speakers connected to it. Under normal use these features are inaudible. All protection circuits work independent from each other. - Page 17 In the unlikely event of on a non-user-rectifiable fault return the amplifier to your supplier, or an approved service centre. Lab.gruppen cannot be held responsible for damage or injury as a result of the top or bottom cover being removed.
