Caution Some power amplifiers are very susceptible to small surges that may result from the process of switching a preamplifier on and off. Some

like the Meridian 205 or 605 incorporate DC-offset protection that may be triggered by this process. Meridian active or digital loudspeakers are inherently proof against these surges and need not be switched off. In general digital products like power amplifiers, recorders etc. will be unpredictable when they have the digital signal interrupted.

How to change back to Normal

To revert to Normal .

1.Switch off the 518 using the power switch on the back.

2.After half a second, switch the 518 power on again.

Making changes to an existing setup

To make any changes to your custom configuration:

1.Change to Config,

2.make the changes you want,

3.change back to Normal.
