Customising 518, an overview

518 is a very sophisticated device with a huge number of options to allow you to set up exactly the system you need or to experiment with new possibilities.

Programming 518 is a straightforward process and you should not be timid about experimenting. Although the setup is stored in non-volatile memory called EEPROM, the EPROM (which you cannot change) contains default Type settings and you can return to these at any time.

Restoring default settings

1.Switch off any power amplifiers that are connected to 518.

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

3.While pressing the Source key on the 518 front panel, switch the power on again. The display will read:

Type 1

4.Release the Source key

At this stage you can change the Type from 0 – 2 using the n and s Volume keys.

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

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

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, 555 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.

518 has two setup options; Type and Config. These together with Normal and Standby give the 518 four operating states. The following sections give an overview.

Type: an overview

Type just described, restores one of the default settings. No further actions are possible.

Config: an overview

Config mode is used for setting fundamentals of options and control. Consequently in Config the outputs of 518 are muted while you make the necessary choices. The choices available in Config are outlined in the following sections.

Config: control settings

In Config you can make selections that effect the way 518 responds to certain keys. The main choices of this kind are:

∙whether the 518 is to auto-configure, or you will determine the controller in the system.

∙The ‘address’ of the product.

∙whether or not Standby is permitted.1

1Standby is not recommended for 'Pro' or Mastering situations
