Config: sources and inputs

In Config you can also make selections to do with sources, e.g.

∙how many inputs will be active

∙which sources you can select

∙which key on the remote control selects which source

∙the Logo for that input on the 562 display

∙the physical input connection to 562 including by implication whether they are analogue or digital.

∙the secondary analogue input for any digital source

∙the comms type of the source, i.e. whether it is a Meridian controllable source like CD or Radio

∙the address for that source product

Gain: an overview

Gain mode is quite different from Type or Config in that the preamplifier actually functions in this mode. In Gain the front panel controls operate normally – with the exception of the Volume keys.

Gain is used to adjust the level of analogue sources fed to the A/D converter.

Digital inputs have a fixed sensitivity defined by the digital data. Analogue inputs however should have their levels adjusted so that the best use is made of the dynamic range of the Analogue–to–Digital converter built in to

562.Best results will be obtained if the analogue gain for each input is set to provide the largest signal that does not cause overloading or clipping.

The ‘flat response' analogue inputs like Radio, Video etc. have four choices for sensitivity; 0.5V, 1.0V 2.0V and 2.5V for full-scale. Phono inputs using the optional Moving-Coil or Magnetic (MC or MM) module in input A1, also have four settings.

Note An important feature of Gain is that you can adjust the analogue input and output settings while listening to the music. When you feel you have the correct combination of settings you can revert to Normal which protects the settings.

Note The input sensitivities for the 562 digital preamplifier are not expressed in the same way as those for analogue counterparts. Caution should therefore be used in comparing these sensitivities. The input level for the 562, in common with other digital equipment is expressed in terms of full-scale in the digital signal – i.e. more equivalent to the input overload point of an analogue preamplifier. See specifications on page 33.
