ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY II

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.

As this technology uses speaker units controlled by the

negative impedance drive of the amplifier and resonance

generated between the speaker cabinet volume and port, it

creates more resonant energy (the "air woofer" concept)

than the standard bass reflex method. This allows for bass

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.
