Buying an Onkyo a-rv410 amp. Current owner says that the output seems low after a quick test. Unit has been sitting (dry and safe) for 2 years. Owner states it is similar to when the loudness button would be off - just not as strong.
Something internal, or a button switched on or off?

Re: onkyo a-rv410 amplifier output problem
Hi pm, Hard to make an assertion without firing it up yourself. It may be that be has faulty speakers, speakers out of phase, faulty earthing of line out from the source he tested it with. Good chance that it is ok. Take advantage of his concerns, and buy it extra cheap. Good luck

Both of the devices have optical connections, by getting a lead between the two you should hear the high quality sound from the unit. Make certain the optical connection is switched on and assigned to the Onkyo.
Only a record player requires a pre-amp. If it the amp doesn't have a dedicated socket for it.
Hi Chris, not all sources will play to zone 2. Only internal and analog sources. If you want to play your cable box for example you need an analog connection from the cable box to the receiver. Also, the output is very low it needs to be amplified. Thank you, Onkyo USA
First of all, did you test the primary and secondary leads for resistance? They all should be from 2-30 ohms max. If they are, the transformer is fine. If they are open, you will need a service manual which may be on-line. If you need more assistance or would like to inquire about repairing your unit, please visit my website at audoserviceclinic.com. Thank you.
check your amplifier output speaker impedance requirements.. example: 8 ohms...build a speaker 8 ohms in parallel or series connection.. check the impedance using ohmeter ..you must reach the required impedance..
use 1 cell battery to check if you speakers are in-phase...if one speaker did not ..reverse connection and check again ...to give the good sound...hope you understand my english..:)
SMCCARTY, The idea behind bi-wiring speakers is to get the highest quality of sound by getting the sound from two separate sources doing separate jobs. Lower frequencies are harder for an amplifier to produce than higher frequencies. So it is common to give these frequencies to two different amplifiers so each can produce the highest quality of sound. By removing the low end from the top end amplifier, it provides the top end amp more headroom thus reducing the chances of clipping. Clipping can easily be heard from the tweeters destoying not only the sound but your speakers as well. It is common practice in pro and car audio to use separate amps for subbass, low, mid and high; four amps working together to their corresponding drivers (more or less depending on the system and type of audio being produced).
In your case, getting the two different sources from basically the same amp (power supply), would not accomplish the full intent of bi-wiring; it would just make more wiring for the same end result.However still a good thought on your end. Onkyo receivers are great because of their beefy power supplies. Not very many other brands have such strong power supplies. Denon's are close but not equal. Chris-
Unfortunately can't connect it that way. The pre out is only meant to go directly into an amplifier that has all of the same inputs (front/rear, center and surround), not a standard receiver. (Pre amp to amp only, not pre amp to receiver) If your Onkyo doesn't have all the same inputs as your Kenwood preamp has outputs you will just use your standard left/right outputs from the Kenwood to your Onkyo input (CD, Tape, Phono,DVD etc) then use the outputs (front/rear, center and surround) from your Onkyo receiver and connect directly to your speakers..
It could be that you lost the power supply to the surround amp IC or the Ic is defective. It should be mounted on a circuit board attached to the heatsink. Look for poor solder connections first. I don't recall the specifics of this model, but the surround amp IC should be easily located.
Update this with your progress and I'll try to locate the service manual in the meantime.
It's probably salvagable but I doubt it will be cheap or easy. Most likely you have one or more ruined output transistors. If you're into taking things apart and soldering, it might be easy for you. Just look for abnormalities on the transistors, usually a little hole in the center of them or blistering. Replace those and you'll either have it back to sounding good or much closer to it. Most output transistors do not fail without showing visual evidence of it.
