The SA-380 is capable of delivering 380 rock-solid RMS watts for the reproduction of exciting, authoritative theater bass. Its linear power discrete Class G circuitry delivers 380 watts RMS and 550 watts short-term peak power. The design uses audiophile-grade components, including a high-current custom-wound low-hum toroidal transformer. Class G design means the power supply is in dual mode in operation, one for long-term operation, and one for short-term very high power peaks. Servo-control circuitry–This circuit monitors the woofers’ performance. If the servo control detects driver distortion it immediately corrects it, resulting in very high output levels at unusually low distortion levels. A 2-position phase switch and THX-reference click-stop on the level control make operation easy and effective.
