JBL HTPS-400
Owner's Manual

U N PA C K I N G
Feet Your HTPS-400 subwoofer is equipped with 2 sets of feet for use depending on the type of surface the subwoofer will be placed on. Enclosed with this manual is a set of rubber self-adhesive feet for use on hard surfaces, such as wood or tile floors, and a set of spiked feet for use on carpeted surfaces. To install the feet, set the subwoofer gently on a padded surface with the bottom side up. If you are using the rubber feet, attach them to the four corners of the unit, covering the holes. If you are using the spiked feet, install them by pressing them into the holes. The subwoofer may not perform as well as expected if you neglect to attach the feet. Grille Your HTPS-400 subwoofer has been packaged with the grille unattached for shipping purposes. In some applications, such as custom installations, the grille may not be necessary. In cases where a grille is needed, carefully align the grille pegs with the grommets and insert the grille. The grille is not designed for frequent removal, and cannot be readily removed with bare hands. If for some reason it becomes necessary to remove the grille, it should be pried off very carefully with a small, flattipped, jewelers� screwdriver, taking extra care not to damage the baffle or the grille.

SPEAKER PLACEMENT
Experiment with placement for the most accurate and uniform bass response throughout the room. It is important to avoid blocking the grille of the subwoofer. Since the HTPS-400 is videoshielded, it may be placed in proximity to a television monitor. A single HTPS-400 subwoofer meets THX Select requirements for a 3000-cubic-foot room. However, to meet THX Ultra requirements for a 3000cubic-foot room, two or more HTPS-400 subwoofers are required. The preamp output featured on the HTPS-400 simplifies the hookup of multiple units (see page 4).
