User manual JBSYSTEMS SMP 8.2 V1.0

[. . . ] 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. This symbol means: indoor use only This symbol means: Read instructions To prevent fire or shock hazard, do not expose this appliance to rain or moisture. To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance or may even cause damages. [. . . ] There are no user serviceable parts inside. never repair a fuse or bypass the fuse holder. 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. Please use the original packing when the device is to be transported. Due to safety reasons it is prohibited to make unauthorized modifications to the unit. 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. 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. Any damage caused by mishandling is not subject to warranty. Basically this is identical to stereo mode but the inputs of both channels are linked so the output will be mono. In this case you only need to use the input of the left channel to drive both output channels. Both channels are linked in "bridge mode" to obtain a mono output with much higher power. SIGNAL LEDS: these LEDs indicate that a music signal is present at the inputs. CLIP LEDS: The LEDs will light up in the following situations: When the output signal has reached a high level which can result in distortion (clipping). Meanwhile the signal limiters are working to keep the distortion low. While short-circuit happened in the output section. LIMIT LEDS: [only on DIGIT 2K2 and DIGIT 3K6] these LEDs are lit in the following situations: When the output power exceeds the safe working range of the amplifier, the LIMIT LEDs are lit while the current limiters come in action to reduce the dynamic range (current) of the output and bring the amplifier back to its safe working range. In this case you are urged lower the input!While short-circuit happened in the output section and the amplifier is in protect mode. PROTECT LEDS: The protection LED is on in the following situations: During the first seconds after switching on the amplifier. [. . . ] L+R SPEAKON OUTPUTS: use these Speakon connectors to connect your speaker cabinets (impedance >4ohm) in stereo or mono mode. wiring of these connectors is as follows: POS(+) = Speakon connector PIN1+ and PIN2+ NEG(-) = Speakon connector PIN1- and PIN212. BRIDGE OUTPUT: use this connector to connect your speaker cabinet (impedance >8ohm) in bridge mode. In most cases these frequencies only consume a lot of energy without any added value to the music.
