6、06 Stereo Microphone/Line Mixer 8.3 Excessive Noise If the noise is in the form of hiss, the problem is usually due to an input stage set for insufficient gain and then compensating for it by increasing the level. Try in- creasing gain and reducing level. Also, check that the - 20dB rear panel pad s

7、witch is not unnecessarily enabled. 8.4 Excessive hum This is usually caused by ground loops in the system wiring. A complex sound system with many sources separated by significant distance and using sev- eral power outlets has many opportunities for this prob- lem to occur. If possible, feed everyt

8、hing in the system from one power source with a common ground. Use bal- anced input and output connections between widely sepa- rated components. If you need help, get in touch with your Ashly dealer or call an Ashly technical service representative. 9. DIMENSIONS: ?1 , ?*+!,? 1# 1 , ,1, ,1# ,1, ,1#
