batteries, wipe the compartment clean.
Be careful not to drop the remote control.
Be careful not to spill liquid on the remote control.
Do not leave the remote control in the following places:
– hot or humid places, such as near a heater or in a
bathroom
– extremely cold places
– dusty places
5 En
PLACEMENT
The position of the subwoofer is not so critical because bass sound is not highly directional. For a sonorous sound field,
the use of two subwoofers is recommended, although you can obtain a good effect with one subwoofer. (
: subwoofer,
: front speaker)
■When using one subwoofer
■When using two subwoofers
Place the subwoofer on the outside of either the right or the
left front speaker.
Place the subwoofers on the outside of each front speaker.
A
y
If the subwoofer is placed directly facing the wall, the bass
sound may lessen because the sound from the subwoofer
and the sound reflected by the wall may cancel each other
out. To prevent this from happening, face the subwoofer
obliquely to the wall ( A or B ).

If your amplifier can cut off high frequencies from the signals for sending to the subwoofer, connect
the amplifier to the INPUT 2 (LFE) terminal of this unit. This brings you higher sound quality
because the signal routing in this unit is shortened by bypassing the built-in HIGH CUT (high cut)
circuit.

Advanced Yamaha Active Servo Technology II
In 1988, Yamaha brought to the speaker systems utilizing
YST (Yamaha Active Servo Technology) to give powerful,
high quality bass reproduction. This technology uses a
direct connection between the amplifier and speaker,
allowing accurate signal transmission and precise speaker
control.
As this technology uses speaker units controlled by the
negative impedance drive of the amplifier and resonance
generated between the cabinet capacity volume and port, it
creates more resonant energy (the “air woofer” concept)
than the standard bass reflex method. This allows for bass
reproduction from much smaller cabinets than was
previously possible.
Yamaha’s newly developed Advanced YST II adds many
refinements to Yamaha Active Servo Technology,
allowing better control of the forces driving the amplifier
and speaker. From the amplifier’s point of view, the
speaker impedance changes depending on the sound
frequency. Yamaha developed a new circuit design
combining negative-impedance and constant-current
drives, which provides a more stable performance and
clear bass reproduction without any murkiness.
