20 Most Recent Denon AVR-1601 Receiver Questions & Answers

Have you checked whether the front panel of your reciever hinges down or up if it does there may be a cut off button under there which when operated will let the front panel buttons work again

here are two relevant links for hookup and such

I don't think the codes are available online? although if you call the directTV 1 800 # they can give you the program code, really hope this helps?

Is this a new problem, as in it worked before? If it's a new hookup, it's possible the sub you have isn't powered. In which case, it won't work. PRE out is 'preamp' for powered subs.

Please add details of setup so I can help you. For example. My Directv box hooks into my HDTV HDMI. Sound is carried inside that cable. I then get sound on my TV from my Directv RCVR without any other hookup. But I do have more. I use an optical cable to go into my Denon 1312 TV/optical input. Since my Wii, PS3, VCR, and formerly Xbox360 all plug into the HDTV inputs and I use it to switch. The Denon is not HDMI capable so this is best for me. This is the first thing I would try. hook the HDMI to your HDTV from the CATV/SAT box and turn up the sound on the TV. [Box and TV on and correct input used] If you hear audio, the hook it back up as before. Now, turn on the Denon to radio. and turn it up. Got sound? NO: check speakers and speaker setting. Let's say you have speakers hooked to A but not B. is the selector on B or AB. That won't work. It has to match the hookup. If speakers are on A only, select A only, etc. Also check with known good speakers. Also check all cables to be plugged into the correct spot and plugged in fully. Thanks PM me if you need more help.

This question does beg for more details. For instance, some HDTVs have an optical out which can be hooked into the Denon. This works great when the unit doesn't have HDMI I/O. I have one such Denon unit [1312] which I bought for that exact purpose. It's all I could afford, and it works. You do have to have the rcvr set on TV or whatever the optical in goes to. Or, some people have a newer Denon and setup their RCVR to switch and only one TV input from the RCVR. then it's the cable box connection you need to check/switch to. it's not simple, but it's not that hard either. I you need more help you can PM me.

That unit is not setup for iPad control. You can plug the audio out from the iPad to either the front audio in or CD/Tape IN using a 3.5 M to RCA M cable/adapter

could be a couple things. Either a blown channel in the amp, or a bad voltage regulator. would have to investigate further with a meter to find out.

all components should go directly to the AVR. Then the video only to the digital TV.
