The master MQA file is fully authenticated and is small enough to stream or download. Visit mqa.co.uk for more information. HA500H includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The LED light next to MQA logo on the HA500H screen glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner. The MQA logo is a trade mark of MQA Limited. 6. Troubleshooting 1) There is no power. 1-1) Make sure the power cord is connected. 1-2) Check the HA500H is switched ON at the rear panel. 1-3) Make sure the plug is fully inserted into the wall socket. 2) The HA500H does not respond to the remote control. 2-1) Replace remote batteries 2-2) Check for interference from other IR sources 2-3) Reduce the distance between the remote control and the HA500H 3) No sound from the speaker during music file play back 3-1) Check if the MUTE function in ON 16 3-2) Check all cables connected to each device. 3-3) Check the volume level 3-4) Check if input source is selected properly 4) There is a hum coming from the speaker. Make sure that all cable connections are secure. 17
