would this be compatible with HKTS 16BQ 5.1 Channel Home Theater Speaker Package (Black)

Asked by: reynaldo
As the HK3700 is a stereo receiver, It can only connect 2 speakers to it. If you're planning to use 5.1 then I would recommend the AVR 1610S for you to experience the full potential of 5.1 surround sound.

Can I use a wifi extender (such as TP LINK WA850RE) connected to the NETWORK plugin in order to cast music through wifi?

Asked by: Gonzalo Miloz
If you mean that you will send audio signals using the Wifi extender to your devices then It will not work. The Network is mainly used to get online and access Vtuner.

Can I use the RECORDER REC OUT pair of RCAs to connect an external amplifier?

Asked by: Gonzalo Miloz
Yes. You can run an external amplifier through the REC OUT of the HK 3700. Please note that the REC OUT, though, unlike a PRE OUT, is not affected by any tone and volume controls that will be done in the HK 3700 receiver.

Hi, I want to know what&acute;s the difference between HK3700 and HK3770, is it the stereo power? And in HK3700&acute;s case, if I connect two pair of speakers, Sp1 and Sp2, the unit will drive 42 watts per pair right? Is that enough for ambient music in the garden?

Asked by: Gonzalo Miloz
Yes, the stereo power for the HK 3770 is a lot higher driven at 120W x 2 channels into 8 ohms compared to the HK 3700 which is driven at 85W x 2 channels into 8 ohms. On top of that, the HK 3770 offers additional connections like Bluetooth, (1) coaxial audio input, and (2) optical digital inputs. You are correct in the case of the HK 3700, when connecting 2 pairs of speakers. It will be driven at 42W per pair. However, in terms of producing ambient music, this is very subjective. While the HK 3700 offers sufficient power for a quaint, cozy space, if you have a large and wide garden, I would suggest getting the HK 3770.

Hi there, would this receiver work through 4ohm speakers?

Asked by: PV11
Yes, the HK3770 can run 4 ohm speakers but this is ONLY possible if you only use one pair of the speaker terminals being that it has two sets of left and right.
