RBH Sound A-504D Quick guide

RBH IN-CEILING SPEAKER INSTALLATION AND INSTRUCTION MANUAL
Congratulations on your purchase of an RBH loudspeaker system! Your speakers are the result of many years
of research and development dedicated to producing high quality products for home audio and audio/video
systems. This manual is designed to give you, the installer or owner, basic information as to the speakers
installation and operation.
RBH in-ceiling speakers have been designed to make installation as easy as possible. Upon opening the
speaker boxes you will notice that the screws are prestarted into the dog legs. As shown in the diagram
below, installing RBH inwall speakers is easy and quick.
If using a New Construction Bracket (NCR-R) for the size of speaker being installed, cutting the drywall should
not be necessary. To install, attach speaker wire observing polarity, then position all dog legs in toward the
speaker magnet. Slide the speaker into the drywall, then tighten the screws. The dog legs will automatically
swing out and tighten (pinch) themselves against the New Construction Bracket (NCB-R) and the drywall
with the turning of the screw and will hold the speaker solidly in place. If using a drill/driver, set clutch to
a low setting to prevent overtightening and possible damage to the frame or dog legs. If using hand tools,
tighten just until rm.
When not using an New Construction Bracket (NCB-R), a cutout template is supplied with the speaker for your
convenience in cutting the drywall. After the hole in the drywall is made, install the speaker using the same
method described above. RBH inwall speakers can be installed into either the wall or the ceiling.
All RBH in-ceiling speakers use a swing out dog leg mounting system with pre-started screws for fast and
easy installation. RBH in-ceiling speakers feature directional swivel tweeters* used to direct the sound to the
main listening area. The TK-615, MC-615 and MC-815 feature polyswitch protection circuitry that is designed
to protect the tweeter from being overdirven. This circuit will automatically reset itself once the volume is
turned down or the problem causing the circuit to activate is removed.
FEATURES
Steep acoustic slope crossovers are used to integrate drivers. The use of steep crossover slopes allows high
power handling, minimizes driver interaction anomalies, and maximizes the clarity with which each driver is
able to produce its respective frequency band.
INSTALLATION
PAINTING
RBH inwall speakers and grilles can be painted any color to match any decor. A plastic paint shield is sup-
plied to protect the speaker from becoming damaged during painting. This plastic paint shield must
be removed before operation of the speaker begins.
*Except A-504D, A-505R, A-506

In order to extract the best possible sound from your speaker system, it is important to determine where
the speakers will sound best in your listening room . First, consider your primary listening location and the
aesthetics of the room. Second, we recommend that the distance from the listening position to each speaker
should be close to the distance that separates the two main speakers. Angling the tweeters inward towards
the listening position may give a more spacious and realistic soundstage.
SYSTEM SETUP
DESIGN PHILOSOPHY
RBH in-ceiling speakers are designed on an innite bafe conguration. This means that a back box is not
required for the speaker to perform properly. However, using the RBH BBR (Back Box Round) will most likely
improve the tightness and control of the bass response.
