User manual B&K AV6125

[. . . ] Do not stack anything on top of the amplifier (preamplifier, processor, source. . . etc. ). Leave at least 2-3 inches clearance from the top of the amplifier to the next shelf, component, etc. , to ensure proper ventilation. * If you are at all unsure of what the speaker `ratings' are, contact your dealer. Page 2 13002 rev 0004 The AV6125's purpose and function The AV6125 is a compact, very efficient, six channel power amplifier. It is designed to be used in all types of audio or audio/video systems. Design and construction The AV6125 utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent, and highly musical sound can be realized. The high quality parts complement include state-of-the-art solid state devices, 1% metal film resistors, computer grade electrolytic power supply capacitors, and a high capacity toroidal transformer. [. . . ] We recommend the following as a means of helping you reach that goal: Make a diagram of your proposed system by laying out the relative location of each component in the system. Then lay out the proposed cable runs between them. Number each cable and record its length on the diagram for future reference. Cable runs are critical in that they must be kept away from sources of power radiation (amplifiers, power cords, heaters, etc. . . ). For the sake of safety, they should also be kept out of traffic areas. The process of optimizing the system will include the type of cable, the length of the run, and the obstructions it must deal with along its run. Your dealer can advise you on the products available and their relative merits. If building custom length audio cables is not your strength, your dealer should be able to help you with that as well. When possible, use a separate AC power line for the amplifier, one that is not shared by any other component in the system of any other house hold component. Tip: Take a piece of stout string (longer than the longest cable run) and mark it at each foot of length. Then do a mock cable run using the string, dressing it neatly along the way. Count the divisions to the next full foot, and add one foot to allow for some movement of the components. This will provide you with the ideal cable length. Making the connection Before doing anything, ensure that the power switch on the amplifier's front panel is in the `off' position. Again, it is recommended that you locate a separate AC power outlet for the amplifier, one that is not shared by any other audio component in the system or any other house hold component. This will eliminate the possibility of the amplifier `modulating' the power being supplied to the component and compromising the signal originating from that component. Locate the AC power cord provided with the amplifier and plug it into the power input receptacle in the rear panel. Do not connect it to the AC power source yet! Page 7 13002 rev 0004 Connect the audio cables from your preamplifier's output to the corresponding input connector on the amplifier. Connect the wires from your speakers to the appropriate outputs on the amplifier. It is absolutely essential that you observe correct polarity in these connections. Example: If you connect your left front output of your preamplifier to channel 4 input on the amplifier, remember to connect your left front speaker wires to channel 4's outputs. Always observe polarity when connecting speakers, connect amplifiers (+) to the speakers (+) and amplifiers (-) to speakers (-). Double check all connections. Connect a playback unit (CD, VLD, Tuner, etc. . . ) to the preamplifier. Turn the volume on the preamplifier to minimum. Turn on the preamplifier, then the amplifier (in that order).
