Don't cover any ventilation openings as this may result in overheating. Prevent use in dusty environments and clean the unit regularly. [. . . ] Peak limiter prevents signal distortion Switchable 75Hz / -24dB low cut filter Adjustable input sensitivity: 0, 775V ~ 1, 0V ~ 1, 44V Ground lift switch A plastic cover (included) can be installed to prevent unauthorized altering of the input level. DC fault + high temperature + overload and short circuit protections Balanced XLR-inputs & jack-outputs: daisy chaining of several amplifiers 3 Speakon® outputs: left + right channels + bridge 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.

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. Clean the ventilation holes regularly with a vacuum cleaner. Be sure to turn off the unit before you make changes to the wiring. 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. [. . . ] 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. [. . . ]
