Configuring your A38 amplifier

A38 setup

Adjusting listening settings

The A38 allows you to customise various features of the amplifier to fit your system. Use this diagram to help you navigate through the available configuration options.

In the diagram, the control knob is shown as .

Normally, the display shows the current volume and the control knob is used to adjust this.

Press menu once to enter the setup menu, then press OK repeatedly to cycle through the menu items. When

you have found the setting that you wish to adjust (as shown on the front panel display), you can change the setting using the control knob. Press MENU to store the change and return to volume display mode – or press OK again to move to the next setting.

Note that the menu will time-out after a short period without pressing a button, with the display reverting to the current volume.

The following items can be adjusted from the setup menu:

‘Power On’ state

English

Balance

 

This allows you to adjust the output balance between left and right channels. The display is

 

 

 

also available directly by pressing the front panel Display button.

Volume

resolution

There are three volume-display options to chose from: ‘Standard’, ‘Fine’ or ‘Reference’.

 

 

 

Standard and Fine represent different levels of volume-control sensitivity; the Reference

 

 

 

setting gives absolute increments in 0.5dB steps.

Input

trims

Input trims are used to compensate for variations in output levels of different source

 

 

 

equipment. If, for example, your CD player is louder at a given volume display value

 

 

 

than other inputs, you can attenuate it by using this setting so that it matches your other

 

 

 

components.

 

 

 

Use the source-select buttons to select the input you wish to adjust, then the control knob

 

 

 

to set (increase or decrease) the input volume for that source.

Max

on

volume

This can be used to limit the maximum volume the amplifier operates at when it is first

 

 

 

switched on: the A38 comes on at the (reduced) ‘Max. On Volume’ level if the last-used

 

 

 

volume exceeds this value.

 

 

 

If this item is set to ‘Disabled’, the A38 always comes on at the last used volume, even if this

 

 

 

is very loud.

Processor mode

Processor mode enables you to fix the gain (volume setting) of your A38. The A38 (in

 

 

 

combination with a power amp.) can then be used to drive the front left and right speakers

 

 

 

of a surround-sound system, when fed from a separate processor. The volume of the entire

 

 

 

system can then be controlled using the processor.

 

 

 

Feed the sound from the processor into the AV input, then set the gain of the A38 to match

 

 

 

the amplifiers that drive your other loudspeakers.

Reset

 

Confirming ‘Yes’ restores all amplifier settings to their factory defaults.
