Wall or ceiling Mounting - The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer. Ventilation - The appliance should be situated so that its location or position does not interfere with its proper ventilation. [. . . ] USA and Canadian: AC 120V, 60Hz A label located at the rear panel power connection indicates the AC power input for the unit. For use in the USA and Canada the label will read AC 120V, 60Hz. Do not handle the AP-48 or power cord when your hands are wet or damp. If water or any other liquid enters the AP-48 cabinet, take the AP-48 to qualified service personal for inspection. Location of the AP-48 - Do not expose the AP-48 to direct sun light or heating units as the AP-48 internal components temperature may rise and shorten the life of the components. Care ­ From time to time you should wipe off the front and side panels and the cabinet with a soft cloth. Do not use rough material, thinners, alcohol or other chemical solvents or cloths since this may damage the finish or remove the panel lettering. 1. Product Overview The AP-48 Eight Channel Power Amplifier is capable of amplifying four stereo line-Ievel audio sources (CD players, tape decks, preamplifiers, tuners, etc. . . ) simultaneously in multi-zone, multi-source installations. The eight amplifiers are arranged in pairs to provide four stereo amplifiers. A line level bus is provided to allow two or more of the stereo amplifiers to share the same audio source. With one of the four mono/stereo selector switches in the mono position, two amplifiers can serve as mono outputs. The AP-48 is ideal for applications that require multi-source amplification, while keeping cost and space requirements to a minimum. Features The AP-48 power output per channel is a constant 56 watts into an 8 ohm load and 62 watts into a 4 ohm load. This power output is backed up by a very large power supply that can provide the current and voltage required when all amplifiers are on at full output. All 8 amplifiers are attached to two large heat sinks to allow the amplifiers to run at high outputs for extended periods of time without the internal thermal protection activating. Each of the four stereo amplifiers can be switched to select the audio from the main bus input or from the individual line input. Each of the four stereo amplifiers can be set to play in mono or stereo mode by a switch located onthe back of the AP-48. This will allow stereo in specific zones while mono is in another zone, although the same source is playing. Each amplifier has independent thermal and short circuit protection to allow the problem amplifier to shut down while the remaining amplifiers continue to operate. Russound's AP-48 is proudly manufactured in the USA at our facility in Newmarket, NH.
