RBH INWALL SUBWOOFER INSTALLATION AND INSTRUCTION MANUAL
Congratulations on your purchase of the RBH MCS-88 subwoofer! Your subwoofer is 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 subwoofers installation and operation.
TECHNOLOGY
At the heart of the MCS-88 is a proprietary aluminum woofer. The special aluminum cone combines stiffness, low mass and self damping properties in a manner that allows virtually uncolored presentation of program material. A powerful magnet and extended voice coil give the woofers high excursion capability, which ensures accurate dynamic reproduction.
CROSSOVER
The MCS-88 utilizes a defeatable crossover network. This crossover is fixed at 100Hz low-pass when the switch is set to “On”; the subwoofer will then only play frequencies 100Hz and below. All frequencies above 100 Hz will be reduced by 12dB per octave. When set to “Off”, the subwoofer will play the full range of frequencies. This switch should be in the “On” position when the signal sent to the subwoofer is ‘full-range’ or not previously filtered through a crossover. The switch should be set to “Off” when the signal sent to the subwoofer is coming from a source using a crossover, such as the subwoofer pre-out from some receivers or pre-amplifiers. Please refer to your receiver or pre-amplifier owners manual for proper bass management settings information. This will ensure that the subwoofer is not receiving a signal filtered through two crossovers. We suggest consulting with your installer, or experimenting with the crossover on and off to determine which is best for your system.
PAINTING
RBH in-wall subwoofer frames and grilles can be painted any color to match any decor. A plastic paint shield is supplied and placed inside the grille to protect the speaker from becoming damaged during painting. PLEASE NOTE: This plastic paint shield must be removed before operation of the speaker begins.
