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:
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.
