Why does my Arcam Amplifier sound cut out unexpectedly?
If the temperature of the internal heatsink rises above a safe level, the protection system temporarily removes power to the speakers. Also, using two pairs of low-impedance speakers (6? or less) may overload the Arcam Amplifier, causing it to shut down due to overheating. To adjust the input trim of a CD player or other input device see page 11.
How to fix no sound on my Arcam A38?
If your Arcam Amplifier A38 isn't producing any sound, there are several things to check: * Ensure both the A38 and P38 power amplifiers (if applicable) are switched on. * Make sure the amplifier isn't muted; the A38 displays 'Muted' on the front panel when muted. * Verify the selected source is actually generating audio (for example, if 'CD' is selected, ensure the CD is playing). * Confirm that the AV input isn't selected on the A38 (the light above the AV button will be illuminated if it is). * Check that the speaker outputs are enabled on the A38/P38. The lights above the SP1 and/or SP2 buttons should be lit.
What to do if the sound cuts out unexpectedly on my Arcam A38 Amplifier?
There are a few reasons why your Arcam Amplifier sound might be cutting out unexpectedly: * **Overheating:** If the internal heatsink gets too hot, the system will reset itself once it cools down. * **Low-Impedance Speakers:** If you have two pairs of low-impedance speakers (6 Ohms or less) connected, try reducing the number of these speakers to prevent overloads. * To adjust the input trim of a CD player or other input device, refer to page 11.
Why won't my Arcam Amplifier switch back on?
If your Arcam Amplifier doesn't switch back on, it might be due to a protection mechanism that activates if you try to switch the unit on immediately after turning it off. Wait 30 seconds before attempting to switch it on again.
How to troubleshoot no sound on my Arcam A38 Amplifier?
First, ensure both the A38 and P38 power amplifiers are switched on. Check that the Arcam Amplifier is not muted; this is indicated on the A38 by 'Muted' being shown on the front panel. Verify that the selected source is generating audio (for example, if CD is selected, ensure the CD is playing). Also, check that the AV input is not selected on the A38 (indicated by the illuminated light above the AV button); if it is, press AV again to deselect it. Finally, confirm that the speaker outputs are enabled on the A38/P38, indicated by the illuminated lights above the SP1 and/or SP2 buttons.
