HK 3700 is rated 4.4 out of 5 by 20.
Rated 5 out of 5 by from very good fm reciver I was looking for a stereo only receiver for my bedroom. I am very pleased with the over all performance of the 3700. I'm in a fringe area for most FM stations and use a outside 4 element beam. The reception beats my larger multi channel receiver hands down with dead quiet signals. The sound from my Polk bookshelf speakers and subwoofer are very pleasing. I bought it while it was on sale, so it was a really good buy

The HK 3700 remote will not control the hk dvd 48. Funny thing is it does control an older HK receiver. Is there a way to program it for the dvd 48?

Asked by: papillon
The HK3700 is s stereo audio receiver (not audio/video). It was not expected that it would be used with a DVD player, which has different remote codes than a CD player. This is why it doesn't work. And yes, it does control an older receiver because the remote codes for all of our audio receivers are the same. Unfortunately, the remote control for our HK receivers are not programmable.

I have all my music stored on an external hard drive, can this be plugged into the USB port to play the music files?

Asked by: noname
We would advise against plugging in external hard drives directly to the receiver. We would suggest plugging the External drive to your computer, and plug the audio out of the computer into the receiver for it to play different kinds of music.

So can I connect my laptop to the usb port and play music from it's hard drive?

Asked by: nonames
No, The USB port only supports USB sticks and only plays mp3 music. What you can do instead is to plug in the computer through HDMI or use an auxiliary to analog cable and plug it in to the back of the receiver inputs and have it play different kinds of music.

Do you need to connect with an equalizer to get get a quality sound?

Asked by: Soul brother
Hi! No, you wouldn't be needing an equalizer to get the best audio output since the Stereo receiver is also an amplifier. It will amplify all audio signals from the source going into the speakers.
