User manual GRUNDIG AUD BOY 55

[. . . ] Do not open the inner casing of the speaker under any circumstances. No warranty claims are accepted for damage caused by incorrect handling. Setting up The "surround sound" characteristics of the Audiorama 9000 allow you to place it anywhere within the room. The differentiated surround sound of the Audiorama system fills the room so that acoustically, the loudspeakers remain practically invisible. The stereo effect is thus excellent and never blurred. [. . . ] For optimum stereo effect, the Audiorama 9000 speakers should be placed at a distance of between two and four meters from one another, depending on the room size. If an Audiorama 9000 unit is "hidden" (e. g. behind upholstered furniture or curtains), the sound of this loudspeaker will always be "poorer" than the others and the stereo sound characteristics will deteriorate. Cleaning Use a damp, soft cloth to clean the loudspeakers. ENGLISH The fabric covering of the loudspeakers can be cleaned with a vacuum (low power setting). 9 MOUNTING -----------------------------------------------------------------------------------------Mounting the Audiorama 9000 on the ceiling Caution: The ceiling surface must be strong enough to bear the weight. Use fastening equipment suitable for the weight of the unit (Audiorama 9000 weight including DIN safety = approx. For ceiling constructions such as wood-panelled or dropped ceilings, use suitable anchors and screws. Warning: To avoid injury, this device must be properly mounted on the ceiling according to the assembly instructions. Note: If the Audiorama 9000 is to be used in a professional environment (e. g. in a café), it must be installed by a qualified electrician in accordance with the valid installation specifications of VDE 0100. 1 Select the mounting site and mark the holes on the ceiling with the aid of the mounting plate for the holder. The rated impedance of your Audiorama 9000 is 4 Ohm. Please note that the amplifier used must be able to accomodate a minimum impedance (acc. The related amplifier should provide sufficient output power. An amplifier that provides less output power will produce dangerous distortions for the individual speakers even at moderate volumes. If the sound controls (bass and treble) are turned up at louder volumes, the operating limit will already have been reached. The amplifier generates heavy distortion even when well under the maximum volume. 1 Before connecting the loudspeakers, switch off the amplifier. 2 The loudspeakers must be connected to the amplifier observing the correct polarity. The connection terminals of the amplifier are marked (for example, red = positive pole, black = negative pole). The wires of the connection cable are likewise marked. Connect the marked ­ or red ­ wires of the connection cable with the red connections (positive pole) of the amplifier and the unmarked ­ or black ­ wires of the connection cable with the black connections (negative pole) of the amplifier. [. . . ] Connect the marked ­ or red ­ wires of the connection cable with the red connections (positive pole) of the amplifier and the unmarked ­ or black ­ wires of the connection cable with the black connections (negative pole) of the amplifier. Incorrect connection can lead to sound distortions. Important: Make sure that the two connection cables do not contact each other. A short-circuit could otherwise occur, resulting in damage to the amplifier. 12 INFORMATION -----------------------------------------------------------------------------Technical data Type: Design: 2-way loudspeaker Closed box with 360° sound characteristics Impedance: 4 Ohm Nominal load: 120 Watt Music output: 180 Watt Transmission frequency: 50 to 30, 000 Hz Bass chassis: 2 pieces, 140 mm aluminium membrane Treble chassis: 1 piece, 30 mm, fabric calotte Dimensions: ø 32 cm Weight: Approx.
