AVR 3700

Yes, download the Harman Kardon Remote app to do this.

Yes, Zone 2 can play compatible contents of a USB stick inserted into the front panel of the receiver.

There may be more than one reasons for this problem, but one detail is important: if establishing the connection manually, do not advance the cursor after having written all characters in your password with the up and down arrows. If you jump to the next empty position after the last character, this will be interpreted as an added character in itself, and the password will be wrong.

DVD and Blu-ray Disc copy protection only allows analog video output up to 576p resolution when playing DVDs and Blu-ray Discs. To view video at higher resolutions use the AVR’s HDMI inputs and HDMI output instead of its component video inputs and output.

The Harman AVR App controls your receiver through your smartphone, which communicates via your wireless home network. Please make sure that your AVR is properly connected to your network router, with cable for the smaller models. If you have no wireless home network, you cannot use the app.

Yes, on your computer, enter the IP address of the receiver in the internet browser. In the page that opens, it is possible to change the name.

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.

There are five possible reasons for the receiver shutting down. 1. There is a problem internally with the receiver. 2. There is a problem with one or more of your speakers. 3. There is a problem with one or more of your speaker wires. 4. There is a problem with the speaker wiring done on your system. 5. The unit is overheating. No ventilation. First, check the wiring at every speaker terminal at the back of your receiver and at the back of your speakers. A single strand of speaker wire crossing from one terminal to another would be enough to cause the amp to shut down or go into PROTECT. If you do not find any problems with any of the wiring, you should disconnect all speakers from your receiver. If the receiver continues to go into PROTECT, the problem is in the receiver. Please submit a case on the Contact Us page. They will be able to assist you. However, if it turns on, the problem is elsewhere. Begin reconnecting one speaker at a time. Eventually you will connect a speaker that will cause the receiver to shut down. At this point you have found your culprit. On the other hand, it may just be overheating. You must have at least 2 - 3 inches of space between the top of the unit and any shelf or component above the unit. The unit should not be inside a sealed compartment when being used. The unit must be able to breath. There are very powerful amps in these receivers. If they run too hot, they will shut down. An external fan can help this.

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.

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.
