English PLACEMENT Å ı ( : subwoofer, : main speaker) It is recommended to place the subwoofer on the outside of either the right or the left main speaker. (See fig. Å .) The placement shown in fig. ı is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as shown in fig. Å.
CONNECTIONS Caution: Plug in the subwoofer and other audio/video components after all connections are completed. Connect the subwoofer to the line output (pin jack) terminal(s) of the amplifier. ● When connecting the subwoofer to the SPLIT SUBWOOFER terminals on the rear of the DSP amplifier, be sure to connect the L/MONO INPUT terminal to the “L” side and the R INPUT terminal to the “R” side of the SPLIT SUBWOOFER terminals.

The theory of Yamaha Active Servo Technology has been based upon two major factors, the Helmholtz resonator and negative-impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system.
