I have nt4.0 when i connect my yamaha crw8424..the system recognize de number.. but no sync. then i cant see anything

Hello Tony, you can connect your Yamaha 70eq equalizer to your Denon AVR 787
You have to use two RCA-RCA cables, one goes from VCR or CD-R / Tape OUT, from your Denon (zone indicated with number 3, in your Denon user manual) to Line In from Yamaha and the other from line Out of the Yamaha to VCR OR CD-R / Tape IN of the Denon, (area indicated with number 11, in your Denon user manual) always uses the same set of inputs and outputs on the Denon, VCR OUT and VCR IN or CD-R / Tape OUT and CD-R / Tape IN, in order to listen through the equalizer, you must select the source you want to listen to and then select VCR or CD_R / Tape, according to the connection you have used
You can see on page 16 of your Denon user manual, the connection of a Deck, and for your Yamaha it would be the same
The equalizer can be used only with analog signals
I hope my comment has served you
Greetings Franco Dosil
Hola Tony, puedes conectar tu ecualizador Yamaha 70eq a tu Denon AVR 787
Tienes que usar dos cables RCA-RCA, uno va desde VCR o CD-R/Tape OUT, de tu Denon (zona indicada con el numero 3, en tu manual de usuario de Denon)a Line In del Yamaha y el otro desde line Out del Yamaha a VCR O CD-R/Tape IN del Denon, (zona indicada con el numero 11, en tu manual de usuario de Denon)siempre utiliza el mismo conjunto de entradas y salidas en el Denon, VCR OUT y VCR IN o CD-R/Tape OUT y CD-R/Tape IN, para poder escuchar a traves del ecualizador, debes selecionar la fuente que deseas escuchar y despues selecionas VCR o CD_R/Tape, de acuerdo a la conexion que hayas utilizado
Puedes observar en la pagina 16 de tu manual de usuario de Denon, la conexion de un Deck, y para tu Yamaha seria lo mismo
El ecualizador lo podras usar solo con las se?ales analogicas
Espero que te haya servido mi comentario

First, syncing is the transfer of data between computer software's that are designed to acquire and share with another entity. The sync function usually is embedded in the computer program. Once the computer recognizes compatible software that has several capabilities including transferring data, a USB connection capacity should be achievable. Usually devices that are designed for data transferability should be capable of acquiring a USB connection either as physical cables or wireless Bluetooth technology. The power to sync is contained in the software program. Once software that has sync capabilities is installed on the computer, any USB cable that is attached to an empty port would display a user message asking for further procedures. For example, USB connections on the computer that has media software's would display device recognizes link requiring data transfer. The solution lies in the software that is relied on for sync capabilities. Acquire Windows Media player, Real One player, or ITunes player as downloadable onto the computer to achieve compatibility.

Important Notes

USB ports are available on all computers as versatile connection links to devices that would require communications. The computers original systems are expected to recognize USB cable connection as manufacturers default. Usually, the computer is likely capable of upgrading several software programs that would least communicate with the USB. For example, the program suit installed has compatibility requirements to perform on the computer as an entity. Also, the program suit requires compatibility with USB connection for another device that would be connected to the computer. Attempt to install media transfer programs that are designed with sync features.

I have the same problem. Trouble pairing but finally I got the SYNC to find my U430 and paired but the SYNC never connects with the phone.

hey,dear sir,as we known,the WMV and WMA format from Microsoft have become very common in music download services. However, in this area, they always include DRM protection, that prevents illegally duplication.Songs bought from different companies will have different DRM protection that can restrict you from playing songs on incompatible players.

So now you could undershand why the music in your computer didn't recognize de device but you run the sync and said ok.what can we do ? you only need some removal software to solve this problem . here is a tutorial about how to remove drm from the music from windows media player.hope it will helpful for you

IMPORTANT: To function properly, your Walkman® player must be recognized by your computer as a Media Transfer Protocol (MTP) device. If the portable player was connected to the computer before the Windows Media® Player version 10 or later was installed, it will be recognized as a Mass Storage Class (MSC) device and not function properly. In that case, a different procedure is available to correct this issue.
NOTE: If this is not the first time using your player and it was working properly at one time with no major changes performed (such as restoring the operating system or replacing a hard drive), follow the procedure below: Check for available space on the player using Windows Media Player or My Computer . Restart the computer. Check the connection status again and try to sync the player. Check that the USB cable is firmly connected to both the computer and the player. Check the connection status again and try to sync the player. If the player is connected to a USB hub, disconnect it and connect it directly to the computer with a dedicated USB cable. Check the connection status again and try to sync the player. If the player is still not recognized by the computer, disconnect all devices connected to the computer with a USB connection and restart the computer. After the computer restarts, connect only the Walkman portable player and test the connection again. If the player is still not recognized by the computer, try a different USB port. Check the connection status again and try to sync the player. Under the Common settings menu of the player, format the player using the built-in Format utility. Check the connection status again and try to sync the player. Verify the current Operating System. If it is an upgraded operating system, contact the computer manufacturer for updated drivers for their upgraded operating system. If you are running the Windows XP operating system, be sure you are running Service Pack 2 (SP2) or later. If you did not have the latest service pack, test the connection status again after it has been installed. If you are still unable to transfer music to your player and have not yet uninstalled and reinstalled the driver follow the procedure to confirm that the player is recognized by the computer as an MTP device.

Have you upgraded your itunes to the latest version?

I followed answer # 6, and it worked!! Many thanks.....It's always something, isn't it?

check in your windows explorer folder and open it there

I think I found my answer. With my player connected I went to Control Panel- System- Hardware- Device Manager and under Portable Devices removed my Zen Player. I then went back to Control Panel- Add Hardware- and let the Add Hardware Wizard add my player back.
My Zen Micro Photo now connects to computer and I can charge the battery with no problem.

Uninstall and reinstall HP.
