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)

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.

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 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.
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.

If there is a difference must be in the amp in the Connect or maybe just the power out of the Connect Amp is not enough to really run the speakers correctly. If no difference then try moving the speakers around and see if that makes a difference.

The Connect:amp does not have RCA audio out.

jma,

Probably, you should not attempt to use a CONNECT:AMP in your system. Use PLAY:3's and PLAY:5's because you will not be able to match the level controls of anything else to your satisfaction. You could possibly use a CONNECT and a regular amplifier, but I think that you will run into volume control issues there too. You'll need to operate the follow-on amplifier at a high volume that will be outside of your comfort zone. This could be fixed with a product such as this.

Note that this is not an equipment flaw issue, it is simply a mismatch with your expectations.

Are you saying that you have run out of volume control and the volume is still too low?

No, I'm saying that I have to add about 20% to the volume level of the zone with the Connect:Amp and Speakers to equal the same volume level as the Play:3 or Play:5 speakers. (And this isn't a room size issue or anything like that...)

Obviously it's something that can be managed, but is a little annoying. And the volume control resets anytime you do anything to change room groupings, so you have to sort of recalibrate.
... the speakers hooked up to the connect:amp are definitely quieter.

I hear you, and I guess starting out by saying it's not "loud enough" didn't really capture what I was trying to capture. It just feels like I'm not getting a very "full" sound out of the connect:amp/polk pairing. I'm open to the idea of trying other speakers, but these seemed pretty good.

And then there is still the issue of the volume disparity -- my Play:3s and Play:5s really are at equal volumes when I've got everything playing at once, while the speakers hooked up to the connect:amp are definitely quieter.
jma,

In your brain, try to disconnect "volume control setting" from any judgements about sound quality. If the room plays loud enough, ignore the volume control setting. The volume control settings are about sensitivity, not quality. I'm not throwing SONOS into this bin, but as a general rule I find that the lower quality stuff gets louder at the lower end of the volume control than higher quality stuff. One must turn the volume control farther on high quality stuff for equal output. This loud at low settings is very important out in the department stores. Sometimes I'll lurk in a high traffic store and observe. Customers will remark how "powerful" a unit is if it gets impossibly loud when one "just cracks" the volume control -- this is the one for them to buy.

It is a largish room. I have the speakers on either side of my fireplace (which is in the middle of the room, not at one end.)

As a test, I brought two of my Play:5 speakers from other rooms and paired them in stereo mode, and... Wow. The sound is really exactly what I'm looking for. Substantially more bass than the Polks were delivering. (Which again makes me wonder if I've got something screwed up with my connect:amp or the wiring?)

I may return the amp/polks and buy two more play:5s. That's still a pricey option ($800), and they really don't look as nice, but the sound is great. And I guess I can always use them in a different part of the house some day.
How big is the room, and where are the Polks located with respect to the walls?

The Connect:Amp delivers 55W/ch into 8 ohms and those Polks, whilst of average efficiency, can take a more powerful amp. They are however 'bookshelf' speakers with modest low frequency extension so they're unlikely to shake the room.

If yours is a largish room you may be better served with a Connect plus a separate amp and speakers.
