User manual JBSYSTEMS LM 440 V 1.2

[. . . ] 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. The exclamation point within the equilateral triangle is intended to alert the user to the presence of important operation and maintenance (servicing) instructions in the literature accompanying this appliance. Check the contents: Check that the carton contains the following items: LM430 with AC-adapter or LM440G ~ LM440F User manual Some important instructions: Before you start using this unit, please check if there's no transportation damage. Should there be any, do not use the device and consult your dealer first. [. . . ] It must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. In order to avoid a hazard, the unit shall only be used with the AC-adaptor delivered with it. LM440G ~ LM440F must be earthed to in order comply with safety regulations. Always replace a damaged fuse with a fuse of the same type and electrical specifications!In the event of serious operating problems, stop using the appliance and contact your dealer immediately. Due to safety reasons it is prohibited to make unauthorized modifications to the unit. Do not use volatile liquids such as benzene or thinner which will damage the unit. DIMMER CHANNELS: these are 4 faders used to set the individual dimming levels of the 4 channels. Below each fader there's a flash button to set the output of the corresponding channel to 100% (full) for as long as the button is pressed. The flash buttons all have backlight so you can easily monitor the output of each channel. SWITCH CHANNELS: these buttons are used to switch 4 individual light effects ON/OFF. To be able to use these buttons you must connect a separate switch pack to the DMX-output of the unit. MODE SELECT: used to select 1 of the 4 user modes: HOLD DIM: This mode can be used to control the dimming levels of projectors on a small stage. The 4 faders (2) can be used to set the dimming level of each channel individually. HOLD SOUND: the music is divided into 4 different frequency ranges (bass, middle, high, antibass). Each of the four output channels will respond to a different frequency range. PROGRAM SELECT: When you selected 1 of the 2 program modes (4) then you can use the program select button to choose the program you like. BACKGROUND LEVEL: with this fader you can set the background level (minimum output level) of the 4 dimmer channels. This can "soften" the chaser effects so they become less aggressive. Attention: don't set this fader to maximum, you will not be able anymore to see the chaser patterns or set proper dimming levels for the 4 individual channels. PROG SPEED CONTROL: When the "program speed" mode (4) is selected, you can change the speed of the selected chaser program (6) from slow to fast or very fast (13). SPEED x10 BUTTON: Used to multiply/divide by 10 the speed selected with the speed fader (12). [. . . ] When the problem is solved, simply push the button to reset the circuit breaker. CHANNEL OUTPUTS: (only on LM440G ~ LM440F) Each channel output has its own output socket to connect any resistive and/or inductive (PAR36) projector(s). Always replace a blown fuse with a fuse that has the same characteristics!It's very important to know that the maximum load for each channel is rated at 8A or 1750Watts. [. . . ]
