Sound issues when playing vinyl through the Uniti Atom

Hi new to the forum and the Naim Uniti Atom which I recently purchased,

Apologies firstly if this has been raised before having connected my Rega turntable though the Atom phono even when raising the volume of the Uniti to the maximum setting the volume is barely noticeable and struggling to hear the record which is playing

Welcome to the forum. What phono stage are you using with your Rega turntable? Is it one that has the phono stage onboard?

Yes

From my rega straight into the back of the unit atom thank you

OK, so a Rega Planar 1 Plus.

Are you getting sound from the Atom that varies with volume but still at a very low level (does it also sound a bit tinny - all treble, no bass?)?

The volume and clarity when using any other source
on the Atom is perfect no issues It’s only when I select the Analog source on the Atom when playing vinyl through the Rega am I unable to improve the volume even when pushing the Atom volume control to the max

Which Rega are you using? If I remember correctly, the Atom doesn’t have an in-built phono stage in the Phono In, it is a line level input. So if you’re not using an external phono stage or the Planar 1 with its built-in phono stage you’ll have a very low level signal going in and thus a very low volume.

Hi Eoin, hoping you are well ?

The phono stage -it seems built in, so I am wondering if the Rega is faulty ?

I wondered as well, but it seems you can only use the Planar 1 Plus with the in-built phono stage switched on … so the issue must be elsewhere …

Are you able to connect the turntable to another amplifier?

Yes I edited my reply whilst you were replying , so I think the fault may lie with either tt or amp,

I suspect it’s the inbuilt phono stage

Ah, I missed the answer “Yes”, thanks Ian.

Are you sure it’s a Planar 1+, and not a Planar 1?

Does it say “plus” here?

And if it isn’t the 1 plus, but the 1, you need a phono stage; I think this is probably the cheapest:

If you are new to vinyl ( or more likely ) or haven’t connected a turntable to an amplifier in many years .

For the sake of simplicity a CD or Blu Ray or TV signal may well output at a rate of say 10, a turntable without a special amplifier will out put at a rate of 1 , so all you hear at max volume is a small squeaky sound .

The Rega 1 plus can be plugged straight into your Atom and you will get a tune if you have a Rega 1 then all you will you will hear is what you described

best wishes

Ian

Rega Planer 3 thank you

The Rega was works beautifully with my Marantz PM6007 and had no issues playing them through my Kef LS50 Meta speakers ,it only when I disconnected from the Marantz and connected it directly to the NAIM is where I experience the sound issues

I’ve had a quick look at the spec of the Marantz and it does include a specific moving magnet phono input. The Atom doesn’t, it expects all of its inputs to be “line level”. Line level inputs expect a much higher voltage than a standard cartridge puts out and the cartridge output needs to be amplified before being put into the Atom inputs. The Marantz has the required amplification built into the Phono input, the Naim doesn’t I’m afraid.

You need a phono stage. The Rega fono would be ideal.
