20 Most Recent Denon AVR-1506 Receiver Questions & Answers

Surround sound will only work if the source signal is coded as surround. Many older TV broadcast programs are stereo only. If your surround sound is working with a DVD or blu-ray then the broadcast source is the problem

In regards to your issue with your SA-AK510 turning back on most likely you have a short and/or a bad connection on the unit. So what is happening is the is a charge going to the switch that is engaging the switch again after you turn it off. Note most modern electronics do not have switches like a light switch. They have an electric relay switch that turn off and on the device when the circuit is completed.

The first thing I would do is make sure that your receiver is not still in warranty. If it is I would call Denon's support. If you are not then the first theng to check would be the fuse. I have seen a few devices over the years where the fuse clip is not connected properly and starts to arc which in turn puts a charge on the board. Also you will want to look around in the areas that get hot to see if any of the installation melted off the wires causing you to have some exposed wires.

Hope this helps

In most AV receivers if the standby light flashes after turning on and you don't hear the regular click of the relay engaging after 4 seconds, indicates an output short or amplifier failure. The protection circuit prevents any further damage by not turning on system.
You will need professional help to fix this problem because even to a electronic enthusiast the construction of a typical AVR is not service friendly.

Look for TONE CONTROL

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

what do i do when my DENON AVR-1506 turns on then flashes red and turns off?

The speakers are disconnected with the switch in the headphone jack. If you use headphones regularly and speakers quit working right after a session with headphones, the contact in the headphone jack my have gotten stuck or the relay this switch controls may have gotten stuck. -mark

Did it ever work? Are you certain the sub is getting a signal. It has to be defined. How about the speaker levels adjustment? Did that work? Give us a clue.

Auto poll just selects the first digital input that is live, it is not how you want to setup your receiver. Use the onscreen display and setup each input one at a time to the digital source that corresponds to it.

Let me know exactly what sources you have and how you have them plugged in and I will be happy to walk you through the setup and calibration. I sell the AVR1610 on a regular basis and they are very good receivers.

Let me know the details and we will be rocking in no time. By the way if you have a setup mic for your system throw it away, the manual calibration is alot better.

Don't know this particular transistor but most of the B#### transistors were manufactured by Bendix Corporations Semiconductor Division at South Street, Holmdel, New Jersey 07733. I think most if not all were Germanium PNP high power transistors in TO3 cases. It's just possible that some surplus dealer or electronics buff around Holmdel may have one in the junk box. If not look for a replacement with capability of handling the specified channel power output at the supply rail voltage. Gain is probably not too critical.

May be the power supply check for power to the power supply and the output voltage from it as well !! May need to be replaced ! It cost $125.00 for part and $225.00 for a new one installed !!

Most receivers only handle one sub at a time. If you are deadset on connecting two, you might want to consider how much power your receiver will give to each if you split the signal then determine the power of each sub. If the subs aren't the same you can be sure they will sound strange.

If they are identical and your receiver has enough power to handle them both, examine the connection the subs use to connect to the receiver and split the connection by buying a splitter at a local radioshack.

You will probably be better off using the better of the two subs instead of having both connected. Your sound quality will be more balanced and clear when it comes to bass.
