User manual DYNACORD LX 1600 REV 11-2010

[. . . ] The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficent magnitude to constitute a risk of electric shock to persons. Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or the grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] LX power amps provide the opportunity for retrofitting an internal analogue signal processor board with x-over and filter functions. The easily readable LED display provides a quick overview of the power amp's current operational status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely durable SPEAKON-type connectors. Also located on the rear panel is a Ground-lift switch, which, when needed, helps eliminating ground-noise loops by separating the power amp's enclosure from the circuit ground. In normal operation, all LX power amps are capable of driving loads as low as 2ohms. This owner's manual outlines and explains several other features of your LX power amplifier. Please, make sure to carefully read all of it and mind the instructions. Next to the power amplifier itself, the package also includes this owner's manual, a mains cord and the warranty certificate. Keep the original invoice, which states the purchase/delivery date together with the warranty certificate at a safe place. Generally, installing or mounting LX power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation. Installation of appliances with opposite air circulation within one cabinet or closed rack shelf system is not recommendable. When including appliances in a closed cabinet or rack shelf system make sure to provide sufficient ventilation. Leave a gap of at least 60mm x 330mm (up to the cabinet's top ventilation louvers) for air circulation between the rear of the power amplifier and the cabinet's/rack's rear inner wall. Make sure to leave at least 100mm of space above the cabinet or rack shelf system. Since temperatures inside of the cabinet or rack shelf system can easily rise up to 40°C during operation, bearing in mind the maximally allowable environmental temperatures for all other appliances installed in the same rack shelf system is mandatory (also refer to "MAINS OPERATION AND RESULTING TEMPERATURE"). caution: For trouble-free operation exceeding the maximally allowable environmental temperature of +40°C is not permissible. To prevent the front panel from bending, the use of installation rails or optionally available "rear-rackmount" rails is obligatory when installing the appliance in a rack shelf system or cabinet. The power amplifier has to be protected against: dripping or splashing water, direct sunlight, high temperatures or direct influence of heat sources, high humidity, extensive dust and vibrations. If guaranteeing the listed requirements is not possible on a long-term basis, regular servicing is absolutely mandatory to prevent the power amplifier from possible failure, mainly being caused by negative environmental effects. Condensation on internal parts may occur when transporting the power amplifier from a cold into a warmer environment. In that case operation is only permissible after the appliance has gained the new temperature (after approximately one hour). If foreign objects or liquids have entered the power amp's enclosure, make sure to immediately separate the appliance from the mains power and contact an authorized service center for inspection before continuing operation. [. . . ] The regular output voltage of each amplifier channel A + B is still present at the corresponding output connectors CHANNEL A and CHANNEL B. However, using these signals is not recommendable because of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms connected is not allowable. CAUTION: Operating the power amplifier in Bridged-Mode may result in extremely high voltages being present at the BRIDGED OUT connector. [. . . ]
