FEATURES......................................................................... 1 CONTROLS AND THEIR FUNCTIONS English CONTENTS CONTROLS AND THEIR FUNCTIONS.......................... 1 PLACEMENT..................................................................... 2 CONNECTIONS................................................................. 3 Connecting to such as subwoofer output terminal or line output (pin jack) terminals of the amplifier........ 3 Plug in the subwoofer to the AC outlet .............
PLACEMENT Since the low-end frequencies of audio signals feature long wavelengths, they are almost non-directional to human ears. The super-bass range does not create a stereo image. Therefore, a single subwoofer may be enough to produce a highquality super-bass sound. Note A The placement shown in the figure on the right is also possible.
Note • Unplug the subwoofer and other audio/video components before making connections, and do not plug them in until all connections are completed. • Connecting methods and terminal names on your component (such as an amplifier or receiver) may be different from those used in this book. Please refer to the owner’s manual that came with your component. • After connecting, make sure that cable is connected firmly.
ADJUSTING THE SUBWOOFER BEFORE USE Before using the subwoofer, adjust the subwoofer to obtain the optimum volume balance between the subwoofer and the front speakers by following the procedure described below. 1 2 3 Set the VOLUME control to minimum (0). Turn on the power of all the other components. Make sure that the POWER switch is set to the ON position. * The Power indicator lights up in green.
In 1988, Yamaha brought to the marketplace speaker systems utilizing YST (Yamaha Active Servo Technology) to give powerful, high quality bass reproduction. This technique uses a direct connection between the amplifier and speaker, allowing accurate signal transmission and precise speaker control.
