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,

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

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

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.

Dave

OK. 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.
