Standard setup

Sounds reproduced through speaker systems are easily affected in subtle ways by the conditions in the listening space. To assure optimum performance from this speaker system, give adequate consideration to the installation location before setup.

This speaker system is designed to be used as a single stereo speaker in small room (such as bathrooms, closets, laundry rooms etc.). Usually it should be located above the primary listening position.

Keep the speaker system at least 50 cm (20 in.) away from the edge of the wall or ceiling. If this is not possible, adjust the sound balance by using the speakers’ treble level control.

This speaker system is not magnetically shielded. It should therefore not be placed near TVs or monitors that are sensitive to magnetic fields, as the interaction of magnetic materials can cause distortion of the colors on your TV screen. Magnetic storage media (such as floppy discs and tape or video cassettes) should also not be kept close to this speaker system.

For the installer

Give adequate consideration to the location of installation before the setup of this speaker system.

Check the walls/ceiling to see if they are strong enough to withstand the weight of the speaker system.

Installation is possible on ceiling from 12.5 mm (1/2 in.) to 25 mm (1 in.) thick.

Check the walls/ceiling to confirm there is no wiring, plumbing, beams, studs or air conditioning systems that may interfere with installation.

Pioneer disclaims any liability whatsoever for damage resulting from assembly, improper mounting, insufficient reinforcement, misuse of the product, acts of nature, etc.
