User manual JBSYSTEMS LIGHT AMP 100.2 V1.0

[. . . ] minimum distances around the apparatus for sufficient ventilation is 3cm. Always unplug the unit when it is not used for a longer time or before you start servicing. The electrical installation should be carried out by qualified personal only, according to the regulations for electrical and mechanical safety in your country. Check that the available voltage is not higher than the one stated on the rear panel of the unit. [. . . ] Important: This device left our factory in perfect condition and well packaged. It is absolutely necessary for the user to strictly follow the safety instructions and warnings in this user manual. The dealer will not accept responsibility for any resulting defects or problems caused by disregarding this user manual. To protect the environment, please try to recycle the packing material as much as possible. Check the contents: Check that the carton contains the following items: Power amplifier Operating instructions Mains power cable. CAUTION: To reduce the risk of electric shock, do not remove the top cover. The lightning flash with arrowhead symbol within the equilateral triangle is intended to alert the use or the presence of un-insulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock. For example use JB cables with order codes: 7-0061 (XLR/XLR L=1m) or 7-0063 (XLR/XLR L=5m). for the speakers we ® suggest using the Speakon compatible outputs. Suitable cables are for example JB order codes: 2-0505 (L=5m) or 2-0510 (L=10m). BRIDGE MODE: Both channels are linked in "bridge mode" to obtain a mono output with much higher power. VENTILLATION HOLES: during its operation the amplifier produces heat that needs to be dissipated. The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore is it very important not to cover any of the ventilation openings as this may result in overheating. POWER LED: This white led is on when you turn the amplifier on using switch(2). A few seconds after switching on the amplifier it is ready for operation. You can use these controls to set the maximum sound level of your setup: Turn both controls on the amplifier (3) to the left. Put on some music on and make sure the VU meters on your mixer are at 0dB. (from time to time the red zone is lit) Set the Master output from your mixer to maximum. Open the Gain controls from the amplifier (3) until the maximum desired sound level is reached. Make sure nobody can reach the Gain controls of the amplifier or install the plastic cover (4). (in some cases the DJ is not ) Note: In Mono and Bridge mode, only the gain control of the left channel is used to adjust the input sensitivity. [. . . ] Setting the Ground lift switch to the position "lift" breaks the ground loop between the amplifier and the chassis grounds of various other components in your setup. L+R SPEAKON OUTPUTS: use these Speakon® connectors to connect your speaker cabinets in stereo or mono mode. wiring of these connectors is as follows: POS(+) = Speakon connector PIN1+ and PIN2+ NEG(-) = Speakon connector PIN1- and PIN2® 18. BRIDGE SPEAKON OUTPUT: use this Speakon connector to connect your speaker cabinet in bridge mode. [. . . ]
