11 English A CTIVE SER V O TECHNOLOGY The theory of Active Servo Technology is 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.
12 SYMPTOM Power is not supplied even though the POWER switch is ON. No sound . Sound level is too low. CAUSE The power plug is not securely connected. The VOLUME control is set to 0. Speaker cables are not connected securely. Speaker cables are connected incorrectly.
