1. Ensure your speakers are compatible with the amplifier
The AXA25 is only rated to be used with 8 Ohm speakers and we would not recommend using it with 4 or 6 Ohm speakers.
Using the AXA25 with 4 or 6 Ohm speakers could result in the amplifier overheating, which in the long run could damage the unit.
Protection protocols on this unit may shut it down before damage occurs.
2. Check if APD has any effect on this issue
This product has APD (Auto Power Down) enabled as default. If the device does not receive an incoming signal for 20 minutes, it will shut down.
If your input source is a very low-level signal, it may shut down during playback due to the amplifier not detecting the input source.
You can enable and disable the unit’s APD setting. This can be adjusted by pressing and holding the Power button until the LED flashes in sequence.
The two options below show which option is selected.
Standby flashes 5 times - APD disabled
Standby flashes 10 times - APD enabled
Note: Make sure the unit is On, before making changes to the APD function.
