User manual SONANCE A800DR INS

[. . . ] Never touch the drivers or push objects of any kind into this product through the grilles. Allow a minimum of one inch above and three inches behind the amplifier. The amplifier should be situated away from heat sources such as heat registers, radiators, stoves, or other appliances that produce heat. The amplifier should only be connected to a power supply of the type marked on the back panel. [. . . ] Once you have determined the area you would like to locate your speakers, you will need to do an obstruction survey. Before you cut the hole for the speaker, be certain no joist, conduit, pipe, heating duct or air return will interfere with the speaker. The Virtuoso A800DR speaker requires a hole that is 10" in diameter. There must also be 5-3/4" of depth within the ceiling for the speaker. Position the template where the speaker is to be located and pencil an outline on the ceiling. If you are unsure about obstructions drill a small hole in the center of the circle and insert a coat hanger into the hole to feel for possible obstructions. If no obstructions are found, proceed with cutting the hole using a drywall saw and run the speaker wires. Insulating the ceiling cavity Speaker performance can be enhanced by insulating the cavity with fiberglass insulation. When installing speakers in a ceiling, it is best to lay a sheet of unfaced fiberglass insulation over the back of the speaker. To further improve the sound quality, install insulation in the bays adjacent to the speaker location. This will reduce noise produced by the unsupported drywall. 2 INSTALLING THE SPEAKERS Step 1 Remove the paint plug from the speaker. Attach the wire from your amplifier to the terminals on the back of the speaker. Double check the polarity of the speaker wires, amplifier + to speaker + and amplifier - to speaker -. Proper polarity is critical in home theater installations.

Woofer output Step 2 Make sure the Roto-Lock clamps are in the full clockwise position so that all the clamps are tucked within the cutout border. Note: The maximum clamp thickness is 1-1/4" (32mm) Line level inputs and outputs Speaker level inputs and outputs Power connection The Virtuoso A800DR amplifier uses a 14 gauge EIA standard 120 volt grounded power cable. Never attempt to operate the amplifier from the accessory outlet of another component. Voltage Switch This switch is set in the 120 volt position from the factory. If you are using this amplifier in a country where the voltage is between 220 and 240 volts this switch should be changed to the 230 volt setting. If you are using the amplifier in its 230 volt setting the fuse located above the power connector must be changed. IMPORTANT: Included with the amplifier is a 2 amp fuse for this purpose. Before making any changes to the voltage setting or the fuse make sure the amplifier is unplugged from its power source. Step 3 Tighten the four screws on the front of the baffle. The Roto-Lock clamps will rotate into position automatically and begin clamping. When you notice resistance on the four screws, the speaker has been clamped successfully. The flange is designed to flex and conform to any small imperfections in the wall surface. [. . . ] Listen to music you are familiar with and set the level to your taste. PAINTING THE SPEAKERS AND GRILLES Speakers and grilles can be painted before installation, which will eliminate the "paint scar" if the speaker needs to be removed for service. Speakers may also be painted after installation, but before the grilles are attached. All speakers come from the factory fitted with a plastic "paint plug. " Use the paint plug to protect the drivers while the flange is being painted with the ceiling. Sonance suggests always painting the grilles separate from the speaker. [. . . ]
