I can't get my M-282 amplifier to work with my system.
I have a Denon 1312B system and trying to upgrade to 7.1 via onkyo's M-282. Have tried putting the trigger on all different settings. Changed the settings on the denon. Still no sound
Hello - maybe I can help. Can you please tell me what type cables you are using and the inputs / ouputs to and from your devices
I have RCA cables from the denon receiver going out to the M-282. Then 18 guage in/outs for the speaker cables
what ouputs from the Denon are you using? And to what input on the 282?
RCA outs from the Denon and RCA ins to the 282
Ok please tell me what specific OUTPUT you are using and same for INPUT on 282 please, the exact jack labels
i guess i'm not understanding your question here. are you talking about the cables themselves. From the Denon it says "surr back", on the 282 i put the cables in the audio in
am i missing the question here?
Ok thanks. That is it. Did you first test for 282 audio using FM or other source to verify the speakers are working?
oh....no i haven't.
lemme try hold on
so they're not working. ive actually used these speakers before on my surround system, and they work just fine
Ok so the Onkyo is not working , is there any "protection" light on, or "standby" on the display? Are you able to switch inputs but still get no sound ?
the onkyo light is orange. i think that means on, per then manual. how do i switch inputs? there's only one input on the onkyo
Lets try going into the Denon Audio menu, and navigate to "advanced" and select the AFDM and tell me what the setting are please
what's weird is i tried changing the inputs. I put my computer RCA plug into the input on the onkyo, then put the rca cable output from the onkyo into "dock" on the denon. I hear music this way.
Yes but your looking for the surround rear signal to feed the amp for 7.1. Did you check the AFDM settings
ok, i pressed menu on the denon. There's no advanced menu on the denon
how did i get to the AFDM settings?
i'm sorry. i dont know what AFDM stands for
sorry....how do i get to the AFDM settings on the denon?
Can you please press "adio adjust" and see what the display says
it says Mode - cinema; D. comp - off; surround back - on; default yes no
am i chatting during peak hours when several other customers are online? It has been 10 minutes since the last answer. I can just try again later if most of the chat is going to be like this
Ok good Please select SB channel OUT from the audio menu and make sure that is not OFF, and select DSCRT to ON, also make sure AFDM is OFF then set the SB CH OUT to "MATRIX ON.
i dont see any of those options on the denon menu screen. Can you walk me through it step by step. Again, I have a Denon AVR-1312. All i see on the menu screen is "speaker setup", "input setup", and "option setup"
hello? is anyone here?
I rated bad service because I had slow responses. My question was not answered. My expert left without leaving a comment. I have been on chat for an hour now and made very little progress.
Relist: Other.Very slow responses. My expert didn't seem to know the equipment i was dealing with. My expert left the chat without leaving a comment.
Hello, thanks for contacting us. My name is XXXXX XXXXX X'XX try to assist you with your issue.
Hello. My name is XXXXX XXXXX X can assist you. To lessen the confusion, we will work only on the secondary amp, the M-282. Unplug the unit from power. When you first plug it in, and push the power button, you should hear one click. Within about 5-10 seconds, you should hear another. Can you please tell me if you hear either click? I can explain more when you reply.I may be off the site for a few hours, but rest assured, I will return and look for your response. (Edited by Moderator) I look forward to your reply.Thank you,DaveMaria-ProMod41090.1546696412
Thank you for responding. I don't mean to be rude or impatient with the first expert, but we weren't getting anywhere.
That's OK. You were fine. We are all different, and this isn't a 8-5 job. The experts work as Independent Contractors working on the JustAnswer site. I would like to think that we are all an expert, in at least one main category; some of us more than one. My expertise is audio, and I prefer home audio to all that I do. Sooooo, enough of that.Now to you. Let's get you up and going. The two clicks are great, but I need more of an explanation on the flashing red lights. When it's up and operating correctly, there shouldn't be anything blinking. Can you please tell me what's flashing?Now I need to know about what audio input mode, as well as which input you are using. I assume you are using the A speaker system? As to the speakers, you are running just 2 off that amp?Please let me know ASAP.Thanks,Dave
So it flashes red blinking lights for 5 seconds, then turns orange. Apparently this is part of the normal operating system per the manual.
OK. The turning orange after the red blinking is fine. What I meant by audio input was, is it analog or digital? Sorry, I don't have the manual in front of me. I saw it's only a 2 channel amp, and from your question, I'll have to assume you only have just the left and right analog input, correct? The next thing I'd like you to try is this..Take any RCA patch cable, and with the amp off, unplug the audio input. Before you turn it back on, plug in the new RCA patch cable. Turn it on, and after the second click, just touch the end of the cable, left then right. You should hear a hum from each channel as you do this. If it works this way, we need to go back to the receiver, as this amp is OK. By the way, if this amp has gain(input volume) controls, they should be turned to maximum, and attenuated by the receiver.Let me know.Dave
so it's an analog RCA input. So I tried touching the end of the cable as stated above. There is absolutely no sound coming out from the speakers. I even tried different sets of speakers, and no go. I'm guessing my onkyo is a lemon.
Well, let's not call it quite yet. So you plugged in a standard patch cable to the Onkyo, before you turned it on, and then touched the tip and nothing. Have I got that right? I'll be back in a few minutes. I want to look up something.DaveOK. I'm back, and I believe I have your answer. Remember last night when I told you that if the unit has a gain control(s), aka, input volume, turn it all the way up, and control the volume with your receiver? Well it does have one. It has one control on the back of the unit, that controls both channels. With both units off, turn the control all the way counter clockwise(off) and then, with the receiver on first, the amp will turn on, if you have set the trigger to audio, and then increase the volume with the control on the back of the 282. You should end up with the control all the way up, when you're done making all the adjustments, but you can do it in stages if you like, so you don't blast yourself out of the room.Please let me know. I'm 90% sure this is your issue, as the amp is not in protection, if you hear 2 clicks.DaveAudioExpert41091.102731169
That's great. It just didn't make sense the way you were describing it. If it clicks twice, that means the amp is not causing any protection issues. That said, there may be a hundred other problems causing loss of audio, but not that one.Sure, I can help with the balance issue as well. Just turn off the amp, switch the left and right audio input leads. If the left is now a bit louder, then it's coming from the Denon that way. Once you know that for sure, you can make changes to the gain(volume) for both left and right channels on the Onkyo coming from the Denon.. Like I said before, you should turn the Onkyo to the max, and control it with the Denon. You can have issues with the control on the Onkyo. It's called a tapered control, where in this case, the left and right channels are "ganged" together on the same shaft. If the control is slightly out of spec, one channel can increase the volume faster than the other, but frankly, I haven't seen that issue in over 20 years. It's probably just a minor change that needs to be made on the Denon. More expensive amplifiers, with have separate gain controls for left and right. I could go into all the details, by telling you that they don't even use volume controls anymore. It's all controlled by a microprocessor(computer, in your case, in your Denon), but that's a entirely different question. :-)Please take a moment and rate my answer between 3-5, which will insure that I am compensated for my time and experience. Tips and bonuses, as always, are greatly appreciated. Thank you. It's been a pleasure assisting you.Dave
