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 compen-
sating for it by increasing the level . Try increasing gain and reducing level . Also, check that the -20dB rear panel pad switch
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 several power outlets has many opportunities for this problem to occur . If possible, feed
everything in the system from one power source with a common ground . Use balanced input and output connections between
widely separated components .
If you need help, get in touch with your Ashly dealer or call an Ashly technical service representative .
