User manual PIONEER S-LX70C

[. . . ] When using a graphic equalizer to emphasize loud sounds in the high-frequency range, do not use excessive amplifier volume. Do not try to force a low-powered amplifier to produce loud volumes of sound (the amplifier's harmonic distortion will be increased, and you may damage the speaker). Do not use the speaker to output distorted sound for long periods of time. Do not sit or stand on the speaker, or let children play on the speaker. [. . . ] Connections at speaker and amplifier terminals should be made as tight and secure as possible to help reduce contact resistance. When mounting the speaker onto wall using the bracket, connect the speaker cable before attaching speaker onto the bracket. Do not try to forcibly remove it since doing so may damage the grille. If the cables' wires happen to be pushed out of the terminals, allowing the wires to come into contact with each other, it places an excessive additional load on the amp. This may cause the amp to stop functioning, and may even damage the amp. After connecting the plugs, pull lightly on the cables to make sure that the ends of the cables are securely connected to the terminals. Poor connections can create noise and interruptions in the sound. Be sure to connect wires to the correct terminal polarities (+ , ­) at the speaker and amplifier, or the proper surround effect will not be produced. Firmly tighten the screw [A] that was used to temporarily attach the bracket to the wall as well. To avoid speaker from wobbling or falling off, firmly attach bracket at multiple locations. The following illustration is an example of attaching the bracket with screws at five locations: Screw location [A] and the 4 corners of screw location [B] (recommended). 2 Paste the supplied wall mounting template on the area of installation. Attach the template level to the ground using an adhesive such as tape. Make sure the template is straight to avoid mounting the speaker crookedly. Pasting the template too close to the TV may cause the TV to get in the way of the speaker when installing. Make sure the template and TV do not overlap. Align the bracket (for wall) to the specified location on the template, and temporarily attach with a screw (6 mm diameter screw recommended) at location [A]. Attach the bracket on with supplied screws (long) at the 4 screw holes. this speaker system adopts a unique design that controls the directionality of the sound. Due to this feature, this speaker system must be mounted differently depending on whether it is being installed above or below the TV.
