Setting the sensitivity for analogue inputs

Analogue inputs to 562 are converted to digital signals in a precision Analogue–to–Digital (A/D) converter. The best results will be obtained if the largest possible signal is fed to the A/D converter. To allow this to happen we have provided adjustable analogue input sensitivity.

By setting the sensitivity you also arrange for all sources to be approximately equivalent in volume when you switch between them.

To help you set the inputs we have provided a red light on the front panel labelled ‘Level'. The Level light illuminates when thepeak input signal is 3dB below (about 70%) full scale.

To change the sensitivity of analogue inputs

In Gain:

1.Choose the first analogue input you want to adjust, e.g. select Radio.

2.Use the < and > blue keys on the Remote control to find the analogue input-voltage configuring menu. It looks like:

RAD 1.0V

In this case the Radio input will have a sensitivity of 1.0Vrms for full- scale.

3.Use the and Volume keys on the front panel to select levels of 0.5V, 1V, 2V or 2.5V.

4.Use the 562 to listen to a wide range of material – in this case try a few radio stations. Set the sensitivity to the lowest voltage that you can. A good setting is the lowest one where the Level light flashes rarely or never.

5.Repeat this process for the other analogue inputs.

6.When customisation is complete, switch the power off and then on again to restore Normal mode.

Here are some guidelines:

∙Meridian 204; use a sensitivity of 1V.

∙Meridian 504; use a sensitivity of 2V.

∙Inputs from fixed-level digital sources like CD players, D/A converters, digital tuners etc.; use 2.5V.

∙Inputs from tape recorders or VCRs; start with 2V.

The strongest reason to have the maximum input fed to the A/D converter is to have a good loudness match between analogue and digital sources. The 562 signal path analogue–analogue has a full 16bit dynamic range. It will be most unusual for an analogue signal to have this dynamic range.

For example FM radio is equivalent to 13bits and vinyl LPs only achieve the equivalent of 11bits. If you are particularly concerned not to overload the A/D converter then experiment with lower sensitivities (i.e. bigger voltage numbers). See also page 31.
