Section 4 - Advanced Features 4.1 Labelling of Inputs and Setting Level Offset With the AM-777, in one process, it is possible to label each of the inputs with a corresponding source and to set the respective level offset. This function is recommended only after ALL desired sources have been connected to the AM-777. Setup Labeling Input X Setting Level Offset A list of available labels is shown overleaf in chronological order.
List of available inputs: All types of sources accomodated 1. Input X (default) 15. PC Audio 2. Aux I 16. Phono Stage 3. Aux II 17. Plasma TV 4. Aux III 18. Pre-Amplifier 5. CD Processor 19. SACD Player 6. D/A Processor 20. Tape Deck 7. DVD Player 21. Television 8. DVD Recorder 22. Tuner 9. HD Recorder 23. Turntable 10.HDTV 24. Uni Player 11.iPod 25. Video Player 12.LCD TV 26. Home Theatre 13.Media Center 27. Home Theatre Direct 14.
4.2 Labelling Input X • Press the Menu key on the RCD-777 • Use the Volume+/Volume- to scroll through the labels (see previous page for the full list of available labels) • Press the OK key on the remote to store the new name You will then move automatically onto ‘Setting Level Offset’ 4.
4.4 Setting Fixed Input Level for Bypass Mode When using the AM-777 as part of a home theatre system with an external processor controlling the overall system volume, it is possible to program one of the five input sources to have a fixed level of input such as for a home theatre system of either 0.775V (0dbu) or 1.55V (+6dBu). This allows the 2-Channel music system to be seamlessly integrated into a high-performance multi-channel home cinema system. - Go to Section 4.
Fixed Input 2V = +6dBu or Fixed Input 1V = +3dBu or Fixed Input 0.5V = +0dBu • Press OK on the remote to store the new fixed input Level Warning! By selecting Home Theater Direct mode, the volume of the amplifier will be switched to full. Hence if it is used incorrectly, it will damage the connecting speakers. AMR assumes no responsibility for any speaker damage arising from use of the AM-777.
4.5 OptiProtect® Speaker Overload Protection Within OptiProtect® the AM-777 has an in-built speaker protection circuit. This is primarily a safeguard against equipment failure and/or extreme levels of over-driving the amplifier and speakers. When the display shows: S p e a k e r E n g P r o t e a g e d ! c t i o n This indicates the AM-777 has detected an output condition that could potentially damage the speakers connected to it.
Appendix A - Troubleshooting Symptom Possible Cause Solution With power ON at mains power point • poor/no power plug connection no power is registered • insert the power plug firmly into the AC • blown fuse at IEC/mains plug • check and change IEC/mains plug fuse • incorrect audio cable connections • connect the sources to the AM-777 correctly • incorrect amplifier operation • make sure that the input selector on the AM777 is set to the desired source Strange “blast” sound • check speaker conne
