There are two possible causes.
- Is [MASTER LEVEL] set to the proper position? Adjust [MASTER LEVEL] so that the master level indicator lights up to the orange indicator at the peak level.
- Is [TRIM] set to the proper position? Adjust [TRIM] so that the channel level indicator lights up to the orange indicator at the peak level.
If the sound is distorted even after the input/output level has been adjusted, the level may exceed the power amplifier's maximum allowable input level. Set an appropriate level using [MASTER OUT][ ATT] at the Setting Utility . The level can be attenuated by 25% at -12dB, by 35% at -9dB, by 50% at -6 dB, by 70% at -3 dB. This setting does not affect the master level indicator.
