FAQ

My receiver does not show "DTS HD Master Audio" in the display, even though the Blu-ray disc should have this format. Instead, it just shows "DTS".
With some Blu-ray discs, you have to go to the Settings Menu of your Blu-ray player and select "Bitstream" or "Bitstream Native". This will carry the DTS HD Master signal to be decoded in the AVR, and the AVR front panel should show the correct text.
My subwoofer is silent, except when I select "Small" speakers in the setup menu. However, it works with movies with a separate bass channel.
If you have selected large front speakers, the sub will fall silent with stereo material. It will still play with DVD or BD movies that feature a separate bass track. The solution is to select "PLUS" in the subwoofer setup menu. This switches the subwoofer to be active all the time.
Is it sufficient to put the AVR into standby, before connecting a Source or a TV?
For your personal safety and to avoid possible damage to your equipment and speakers, it is always a good practice to turn off and unplug the AVR and ALL source equipment from the AC output before making any audio or video system connections.
I cannot get sound from headphones plugged into my AVR 70.
In the AVR 70, you must de-activate the speakers in the menu system to activate the headphone output. The easiest way to do this is to connect a composite video cable to your TV in order to see the menus. But you can also use the menu system by looking at the front panel display of the receiver.
I have connected my set-top TV box, my AVR 70 and my TV with HDMI cables. Some of the TV channels work fine, but others have no sound through the AVR 70. However, these same channels do have sound directly from the TV. What can I do?
Your AVR 70 needs a software update. This must be carried out by a service station, and cannot be done in your home. We are sorry about the inconvenience, but the receiver must be submitted for service.
Sometimes when I watch HD or 3D material, I can see white specks or "snow" on the screen. What can I do to avoid this?
Try another HDMI cable, and make sure that it is a high-speed version. This solution usually solves the problem, which is caused by insufficient cable bandwith.
