Do i need to re calibrate the av speaker for adding a extra power amp on front speaker?

[derekchan]

i add a power amp for front speaker,which was used to drive by internal power section of av integrated receiver.
The three floor speaker was calibrated with driving by internal power section of mrx740.
recently i add a power amp for front L/R speaker

Do i need re calibrate now?

 

[Pareto Pragmatic]

Yes.

Well, unless the new amp puts out exactly what the old one did, which is highly unlikely.

I recalibrate for any changes to my system, equipment or position.

may i ask... Does the db adjustment of channel balanced processed by dsp in digital domain,or in analog domain?

lastly,what difference between av receiver and streamer dac for decoding 2chaneel audio ,,Does the better dac that have better sound for 2.0?

If the power amp had the same gain as the avr amps then no, otherwise you can make manual adjustments, or re-run calibration that will do it for you.

Almost certainly digital as the alternative would be more complicated for no benefit.

Re-running calibration is probably quicker and better than wondering if there is a way around it. I would just do it and get done with it the proper way.

I would say that is not the case with Anthem. calibration is, among other things, painfully loud and manually adjusting the channels affected should be much quicker especially if he knows the gain of the external power amp.

Ear plugs could help? I would not speculate and just do it right. Math is math, but not everyone is that good to figure out adjustments based on the gain of an amp - for sure I would not want to go there as opposed to re-running a calibration and be as safe as it gets.

Absolutely, to do it manually one has know the basics, that's why there's auto setup/calibration. As you know, I just don't make generalized, and/or yes no responses "it depends.." is my favorite responses lol, and I do realize it is often not the kind of useful responses people look for.

Possibly, if the streamer has a much better dac/preamp section than the av receiver's, but not for sure and may not be in all cases. For example, the MRX740's dac/preamp section did very well on the test bench, to the point most people would most likely find it totally transparent. So, even if your streamer has the best dac/preamp, it may not "do better" practically speaking, though would measured better on the bench.

I am with you - devil is always in the detail. People are most often looking to push the easy way out button.

For those interested, I would like to add one more point, that is, for a tweaker (like me), after a calibration re-run the manual adjustments will be gone unless one keep a good record (such as taking screenshots or writing things down). A side note: AARCG's phase optimization part is very loud, and tends to take a long time. So, for tweaker who had made a ton of their favorite adjustments/customizations, simply manually changing level trims to level balance their external amps with the internal amps would be much a much quicker and better process than re-running calibration. Also, in my experience, every re-run typically would result in different measured performance verifiable with REW and in that sense I found AARCG is not very consistent, compared to Audyessey and Dirac Live's. I don't want to debate anyone of this so loyal Anthem fans need not bother, unless they also show their REW graphs that support their findings, a tall order, I know.. lol..
