Page 16: 1 Troubleshooting
Troubleshooting Amplifier does not power up If the front LED is not illuminated, follow the procedures below. If one step succeeds in activating the power, stop and ignore the other steps. Check if the AC mains voltage matches the specification of the amplifier which is next to the serial number. - Page 17 Front LED is illuminated as red and no sound When the soft start and DC protection are initiating, the front LED will illumi- nate as red and there will be no sound. Within one minute the LED should illu- minate as white and there should be sound. If the LED still illuminates as red: Switch off the amplifier and test again until it cools down.
- Page 18 If you are using daisy chain, unplug the XLR bypass cables and test only the Unum amplifier which is connected to the source or preamp. If this gives sounds, the bypass XLR cables may be defective. Replace and try once again.
- Page 19 It is highly recommended to directly connect the source (CD player, DAC, and streamer) to Unum amplifier if the source can control the output volume, 2. There is no need to choose signals from multiple sources. This decreases the sources of distortion and retains the quali- ty of the signals.
