Issue with Connect:AMP and Volume

I'm a few months into my Sonos setup, and absolutely love it. Yes, my first (two!) cars didn't cost this much, but I consider it one of the best investments I've ever made. I have 5 zones with a mix of Play:5 and Play:3 speakers, and also using my own speakers -- which is where the trouble is.

In my living room, I have a Connect:Amp hooked up to a pair of Polk RTiA1 speakers (http://www.polkaudio.com/products/rtia1). The sound is... disappointing. I should clarify: The sound is spectacular, certainly more sophisticated than from my Play:3 or Play:5 speakers, which already sound great. But it doesn't seem as "powerful" as it should be, for lack of a better word.

For one thing, with all zones on the same volume setting, my living room speakers are noticeably quieter than the others. I have to turn up the volume in that room by perhaps 20% to equal the volume being played elsewhere. Also, with the volume set somewhere around 5% maybe, there's not really any music coming out of the speakers at all, while my Play:3s and Play:5s are still audible.

And second, it just feels like the overall power isn't that impressive. It's uncomfortable to stand in front of my Play:5 with the volume even close to maxed out, but not so with my Connect:Amp/Polk setup. Turning the volume all the way up is indeed pretty loud, but not the blast I was expecting. Not that I'm aiming for a setup that makes my ears bleed... Just making the point.

I hooked some other speakers up to the Connect:Amp and had the same issue. I don't think the Polks are the problem, and like I said, they do sound amazing for what they put out. (They are also gorgeous!)

What I'm struggling with is whether to keep this setup. Maybe my expectations were too high, maybe I've got something screwed up on the technical side, I don't know. This is by far my most expensive Sonos room, though... About $825 including the Amp ($500) and speakers ($325). I'm wondering if a $600 pair of Play 3's would sound the same or better.

Anyway, eager for any advice anyone has to offer.

This may be a daft question, but are you sure the Polks are wired in phase?

That's my first thought too. Out of phase speakers will give exactly the effect jma describes: vague, washed out, low bass levels and no "punch" to the overall sound.

Worth checking I'm sure.

Just for "giggles" try using your speakers with a different amplifier (using the RCA output jacks on the Connect;Amp) and see if there is a difference in how the speakers sound.
soundhd,

As wadgel notes, Connect:Amp has no RCA outs (other than a low-pass subwoofer feed).

As of now it's still our impression that you own precisely zero Sonos components, so your experience in the use of the products is presumably commensurate.

Helpful interventions are always welcome. When they're inaccurate and misleading they only serve to confuse.

hi jma

i am sorry i don't have any solutions for you, but i can offer my experience. i have a play 3, play 5 and connect amp. the amp is hooked up to dali zensor 1s, and previously a cheap pair of missions that came bundled with whatever the denon microsystem of 10 years ago was.

the connect amp is very loud (on both sets of speakers). i am scared to turn it up to full volume! albeit in a small/medium room.

if you are saying that you can turn it up to full volume, and it isn't ridiculously loud, then that is surprising and not what i would expect, and doesn't sound quite right to me.

p.s. personally i wouldn't worry too much about the volume toggles being "out of sync". factors such as room size and placement has an effect on your comfortable settings, and will presumably vary from zone to zone. that said, the volume on my connect amp zone is generally lower than that of my player zones for comfortable listening.

Just wanted to follow up:

This was driving me crazy enough that before I boxed up the speakers and returned them for something else, I decided to buy a new Connect:AMP just to see if it would make any difference. And... That was it! With the new amp, the sound coming out of the Polks is absolutely stunning. And, yes, loud and powerful: At about 50% volume, my (very large) living room shakes.

I have no idea what the issue could have been that was limiting the output of the old Connect:AMP, but it doesn't matter now. And by the way, to anyone looking for bookshelf speakers, I can enthusiastically recommend the Polk RTiA1. Price pretty much everywhere is about $325 for the pair, and they easily sound as good as speakers costing three times as much. (And as I mentioned before, they really look gorgeous.)

Thanks for all the suggestions everyone.

Can someone help me to solve my issue with connect:amp left hand output volume extremely low?

I have 2 connect:amps and both are giving the same output issue.

I have tested it in 2 different set of speakers and in both (and also both amps) the issue is the same. After 1 second, volume of the speaker in the LH is turned automatically to very low level.

If someone knows what may be the solution, please let me know. I am getting crazy with it.

I am using Atrium45 outdoor speakers and another set of old speakers (6 ohms)

Bruno Santos,

First post! Welcome to the forums.

Are you using the same speaker wire in all of your tests? Are there any volume controls or switches in this circuit? What happens if your exchange left and right at the back of the CONNECT:AMP?

Buzz, I have tested all speakers in all positions and the output issue is always the same. Left output from sonos amp is extremely low, but as I have two sonos connect:amp and both have the same issue I can not believe in an amp internal failure.

So answering your question, when I swap wirings in the back of the amp, the issue continues in the same output ports of the amp, migrating the low sound level to the other speaker

Perhaps this is too simplistic, but could it be that your Music Equalization "Balance" setting for the problem zone is offset to Right channel only? This would explain why two CONNECT:AMPs show the same apparent "fault".
SONOS rules! 8 Zones and counting!

Buzz, thank you for the attention.

I have spent few hours today over this issue and now for my personal surprise it is the radio that I was selecting!!

Honestly I can not understand the reason as I would believe that even mono radios would play LH and RH speakers!

Thank you again for the attention!

I was checking it also and everything was fine .

Now for my surprise it is associated with one radio (radio mpb fm) I am not able to understand the reason
