Is [MASTER LEVEL] set to the proper position? Adjust [MASTER LEVEL] so that the master level indicator’s orange indicator lights at the peak level.
If sound is distorted even after the output level is adjusted, the output to the power amplifier may exceed the maximum allowable input value of the amplifier. Use [MASTER ATT] in utilities mode to set the input to a suitable level. The level can be lowered to 25 % at -12 dB and 50 % at -6 dB. This setting is not interlocked with the master level indicator.
