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.

Hi I have a HK AVR370/3700 I have a Pana TH EX780 75" 4K TV and UBT1GL-K BluRay recorder. The Receiver will not pass through HDMI 2.0a HDR capabilities as it is only 1.4. Can you suggest best way to connect everything up?  I have a HDFury AVR Key also.

Asked by: PhilG
Thank you for your inquiry. Since the AVR can only handle HDMI 1.4, the best way to set this up is to connect your 4K Blueray recorder to the TV so it would display the 4K content and connect the AVR to the TV so it will only receive the audio and play it without issues.

When connecting to pre-out terminals to separate amplifier, does this disconnect the avr's power amps, do they shut off or are they still active?

Asked by: connerdude
In your scenario, the internal amp stays active. If you have no need for the internal amp, simply don't connect any speakers to the speaker terminals. This will make them inactive as there will be no load on them, so they would not produce any wattage.

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.
