User manual ELECTRO-VOICE Q1212

[. . . ] 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. install in accordance with the manufacture's instructions. 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. [. . . ] Even if amplification has been reduced through lowering the input level controls on the amplifier's front panel, it is still possible to achieve full power output with a sufficiently high input signal. Q amplifiers are capable of producing dangerously high voltage output that is present at the output connectors. To protect yourself from electric shock, do not touch any blank speaker cables during operation of the power amp. WARNING: The terminals marked with are hazardous live and the external wiring connected to these terminals requires installation by an instructed person or the use of ready-made leads of cords. Changes or modifications not expressly approved by the manufacturer could void the user`s authority, granted by the FCC, to operate the equipment. NOTE:This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection agains harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected · In a domestic environment this product may cause radio interferences in which case the user may be required to take adequate measures. This Class A digital apparatus complies with Canadian ICES-003. The power amplifier receives its power supply via the Mains input. Only the provided power cord may be used. During installation, always separate the power amplifier from the mains. Connect the power amplifier only to a mains network, which corresponds to the requirements indicated on the type plate. The Mains Switch on the front panel separates the power amp from the mains. Turning the Mains Switch to ON starts booting up the power amp. A soft start circuit compensates mains inrush current peaks and thus prevents the automatic cutout of the mains from reacting when switching on the power amplifier. Speaker system switch-on is delayed by approximately 2 seconds via output relays, effectively suppressing any possible power-on noise, which otherwise might be heard through the loudspeakers. PROTECT-LED lights up and fans are at high speed during this delay. This indicates all protections are working fine. Attach the power amp with its frontal rack mount ears using 4 screws and washers as shown in following illustration. [. . . ] Using the input level controls on the power amp's front panel allows independently adjusting the channels' amplification. Using the input level controls to independently control the amplification of the two channels is still possible because only the channels' inputs are linked. In DUAL and PARALLEL mode, the level controls CH A and CH B on the power amp's front panel are used to control the amplification of the corresponding channel. Turning the control to the right increases and turning it to the left decreases the volume. [. . . ]
