No ventilation.\r\n\r\nFirst, 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.\r\n\r\nIf 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.

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.

Rated 5 out of 5 by from Superbly Powerful I purchased this about 3 months ago as a replacement for an AVR 8000. I too was concerned as to wether the newly designed amplifier in the AVR 3700 was still able to produce the same seamless power. It does. This receiver sounds just as beautiful with your favorite film as well as your favorite track. I cannot say enough good things. The on screen user interface is extremely intuitive and easy to use.

Is this compatible with Harman kardon HKTS 16? I will be using just the 5.1 setup. Can this AVR be configured to work just with 5.1 sound system?

Asked by: Music Lover 4
Yes, the HKTS 16 would work well with the AVR 3700 as the 5.1 speaker system.

Hello, Does the 3700 have pass thru capabilities while unit is in standby / off mode? Meaning, can we watch TV without the unit being powered on? Thank you!

Asked by: kamaaina1
Unfortunately for HDMI pass thru signal will not work, on the other hand if you will be using Optical connection from the TV going to the receiver. You can turn off or put the AVR on standby and set the TV speakers on to watch TV without the System.

If I have 2 HDMI sources can I drive 7.1 audio from source 1 AND pass through source 2 HDMI at the same time?   Also, can I have source 1 (or 2)  go out BOTH HDMI outs?

Asked by: DaveS
No. There is no way to output two different digital sources at the same time. This is only possible to the extent of using the Zone 2, but the Zone 2 is only limited to play analog sources.

Whats the best amp you recommend for the HKTS 20 that has bluetooth, wifi, optical and HDMI?

Asked by: JorgeRBQ
The AVR 3700 can be connected to the home network to play through DLNA/Airplay but does not have Bluetooth. The AVR 1610S would be your best bet, this receiver can provide you 85W per channel on a 5.1 system, ability to connect to a home network that will allow you to access vTuner Internet Radio and DLNA to stream audio from compatible devices. The AVR 1610S does have Bluetooth in which you can directly connect your Bluetooth enabled source devices. This model does have multiple HDMI and Optical ports that you can use depending on your source or preference.

Does the AVR 3700 and/or AVR 1610S Amp work with the HKTS 20 Home Theater System?

Asked by: JorgeRBQ
Yes, both the AVR 3700 and the AVR 1610S would work with the speaker for the HKTS 20. Though, the AVR 3700 can drive 125W per channel, than what the speakers can safely handle, which is 5W more than what the speakers can handle, it can still be advisable. The AVR 1610S can drive 85W per channel which can be handled safely by the HKTS 20’s speakers which are rated at 120W.

How can I connect my iPhone via a wireless connection to the receiver? Is it a dlns connection, Bluetooth, or something else?

Asked by: aFunkyrobinson
The AVR is DLNA-compatible and can access MP3 and WMA audio media that is stored on other DLNA-compatible devices that are connected to the same network as the AVR. With that said, if your iPhone is DLNA compatible then you can connect your iPhone to the AVR wirelessly.

can i connect my phone via aux cable

Asked by: Eddd
No, the headphone jack output on the AVR 3700 is used to connect a headphone for private listening. It cannot be used on a phone via AUX cable. You can, however, use any stereo mini headphones to dual RCA cable to connect your phone to any analog input on the back of the AVR 3700.
