19、D PROCESSOR IMPORTANT NOTES 1. Show the software version Press “DVD” and “SAT” at the same time. 2. Light up all the icon on the VFL Press “CD” and “TAPE” at the same time. 3. Reset Press “FM MUTE” and “PRESET/TUNE” at the same time. When VFL shows “Resetl1 REQ?”, press “OK” button. For CE version,
20、the 9K/10KHz switch should be set to 9KHz and the voltage should be 230V AC. For UL version, the 9K/10KHz switch should be set to 10KHz and the voltage should be 115V AC. The 4/8 ohm switch should be set in 4ohm position in all version. Ground-SW: GROUND. 4. Upgrade MCU software The software of main
21、 CPU P89C669 can be upgraded via RS232. The programming steps are as follows: Connect the AVP700 to the computer. On AVP700, press the buttons RDS INFO and STORE at the same time. Then the front panel should display Program Req.:. Then press OK button. Or you can press RDS INFO and STORE for 3 secon
22、ds. Front panel will then display Program. The AVP700 is ready to be programmed. Note: when the program process is stopped unexpectedly, the program in IC may be erased. You can press these two buttons for 3 seconds for programming. Run the AVP700test.exe and click the button Program to CPU. Select
23、the appropriate COM Port and click the “Browse” to load the hex file. Then click the button Program. Upon the upgrade process is completed, a pop window will be shown. Note: Please try it again if there is error response. RadioFans.CN AVP700 SURROUND SOUND PROCESSOR - 8 - 9 - AVP700 SURROUND SOUND P
24、ROCESSOR 5. Upgrade DSP software DSP code in Flash Rom AT29LV040A can be upgraded via RS232. Connect the AVP700 to the computer. On AVP700, press the buttons RDS INFO and FM Mute/Mono at the same time. Then the front panel should display Program Req.:. Then press OK button. Or you can press RDS INFO
25、 and FM Mute/Mono for 3 sec- onds. Front panel will then display Program. The AVP700 is ready to be programmed. Note: when the program process is stopped unexpectedly, the program in IC may be erased. You can press these two buttons for 3 seconds for programming. Run the AVP700test.exe and click the
26、 button Program to DSP. Select the appropriate COM Port and click the “Browse” to load the s28 file. Then click the button Program. Upon the upgrade process is completed, a pop window will be shown. Finally, use Dolby, DTS, PCM test discs to see if all decodings are ok. This ensure the DSP has been
27、upgraded successfully. 6. HDMI check AVP700 contains two HDMI inputs (DVD, SAT) and one HDMI output. It functions as a 2 x 1 HDMI switch. Equipment used: 2 sets of DVD player (Arcam DV79) with HDMI output. (Support 720p/1080i) One HDTV support HDMI input (option 1) or C9993i demo board with another
28、YUV supported TV (option 2) 3 15m-HDMI cables RadioFans.CN AVP700 SURROUND SOUND PROCESSOR - 8 - 9 - AVP700 SURROUND SOUND PROCESSOR Test set up: Procedures: 1) Make sure all of equipments are OFF. Connect all grounds of equipments. 2) Connect the system as above. 3) Power on all units and set the D
29、VD1 with 720p HDMI output (If Samsung DVD is used ), DVD2 with 1080i HDMI output (If Samsung DVD is used). make sure that both DVD players have two copy protected DVDs inside. Note: If DVD79 is uses, please use below settings: Force DVI: No Output priority: HDMI/DVI Digital Video: RGB Progressive: O
30、ff Audio: PCM/2ch 4) On AVP700, switch to DVD source, the output signal on TV should not have any noise or snow. Both speakers should have output. 5) Repeat the same for SAT source. 6) Switch to other sources, there should be not both audio and video output. 7) Select to different sources, observe b
31、oth video and audio output. They should run properly.
