User manual JBSYSTEMS LIGHT AX V1.2

[. . . ] ⷠDon't cover any ventilation openings as this may result in overheating. ⷠKeep this booklet in a safe place for future consultation. If you sell the fixture, be sure to add this user manual. ⷠTo prevent fire or shock hazard, do not expose this appliance to rain or moisture. [. . . ] This means that both channels are switched together in series to act as one mono amplifier. the output power nearly doubles compared to the separate channels. However the impedance of the connected speaker cabinets must be twice compared to that of normal stereo mode. In bridge mode, you have to apply the signal only to the left input of the amplifier. For more information refer to point (11) in the next chapter. Attention: Take care not to use speaker cabinets with a total impedance lower than 8. 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. This means that both channels are switched together in parallel to act as one mono amplifier. the output power nearly doubles compared to the separate channels. However the impedance of the connected speaker cabinets must be half compared to that of normal stereo mode. In parallel mode, you have to apply the signal only to the left input of the amplifier. For more information refer to point (11) in the next chapter. Attention: to be able to produce the indicated power, the total impedance of the connected speaker cabinets must be around 2 !POWER LED: This blue 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: · Put on some music on and make sure the VU meters on your mixer are at 0dB. 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. You have just set the maximum level the DJ is able to produce. (in some cases the DJ is not ) Note for VX200 and AX700MK2 / VX700MK2: In Parallel and Bridge mode, only the gain control of the left channel is used to adjust the input sensitivity. [. . . ] We suggest using red/black cables (such as JB Systems order code: 935). It is very important that you don't switch the + and ­ poles of the outputs. This results in very poor sound reproduction without low frequencies!There are 3 ways to connect the speaker cabinets using the binding post connectors: GROUND LIFT switch: In some cases nasty hum noises can occur due to ground loops in your setup.
