Troubleshooting

If you are having trouble with your amplier, check the

following items.

No sound

Check the following:

< e A28 amplier is switched on.

< e amplier is not muted (i.e Mute is not shown

on the front-panel).

< e selected source is generating audio (e.g., if CD

is selected, then the CD is playing).

< e AV input is selected on the A28 instead of the

expected source. In this case, press AV again to

de-select the AV input.

< e speaker outputs are enabled on the A28/P38,

as indicated by the lights above the SP1 and/or SP2

buttons (as appropriate) being illuminated.

Sound cuts-out unexpectedly

If the temperature of the internal heatsink rises above

a safe level, then a thermal cut-out inside the amplier

operates to protect the unit and the protection system

temporarily removes power to the speakers. e system

will reset itself as the heatsink cools down.

< With two pairs of low-impedance speakers

connected (6Ω or less), overloads are more likely.

Overloading the amplier may cause it to shut

down because of overheating.

< Note that, due to the high output voltage from a

CD player, it is possible to drive your amplier at

full power even though the volume is not set at

maximum. See page 11 to adjust the input trim of

a CD player or other input device.

Amplifier does not switch back on

Both the ampliers detailed in this handbook have a

protection mechanism which is activated if you switch

the unit on immediately aer turning it o. If this

mechanism activates, wait 30 seconds before switching

the unit on again.
