Thanks for the interest and help guys. I’ll get back to this at some point. Too busy at the moment.
There’s no diagram for the circuit board and some have no reference so it might be difficult to find components.
Cheers

Alpine CDA-9833
Alpine CDA-9833
Ive got this stereo open at the moment and the small 12v fan won’t run. I’ve tested it by itself with a Bench PS and it’s working ,just not when plugged into the board when the stereo is switched on.
Any help is welcome.
Cheers.! 🙂

That’ looks like a line input pot. I can’t say for sure but it might be.
I’m using this to the line input and it’s OK.
Even the loud 12” ones don’t peak to 0db. They’re in the - db range.😊
They’ve just set the phono input too high but it’s perfect for LPs as they are lower anyway.

I’ve got a Rod Elliott P06 to build aswell. Plenty threads on that around.
I was talking to him about this unit. He says that you need a pot for audio. It makes no sense to not have one as you have no control over it.
I was trying to make this unit work alone without anything other than maybe putting a small pot in there maybe.
I could upgrade some of the caps in there to better the sound a bit but it works good for LPs.

Hi
Its a 1210mk2. Cartridge is a Stanton 500.
The LPs are a nice volume. It actually sounds pretty good. I was playing all sorts. Al Jolson. Brenda Lee. George Jones. Del Reeves. Eddie Cochran.
I don’t think it’s made for 12” singles. If I somehow reduced the volume. The LPs would be too low then.
The 12s are more than 10db louder. Surprisingly ,one of the LPs peaked around -3.5db too ,but didnt go near 0db.
Yea I don’t understand it either ,I’ve been playing vinyl for over 40 years. I’ve never known a phono input to be loud like that. From Amplifiers...Leave a comment:

I was testing it again with a turntable and Albums are -6 to -8db.
12inch singles are very loud ,I don't know what level they are as they're in the Red most of the time.Leave a comment:

Hi again.
I measured the voltages on the chips.
Im getting +4.9v+ on pin 8 but 0v on pin 4 on both of them.Leave a comment:

Took some photos with a light under the board to see the tracks. [ATTACH=JSON]{"data-align":"none","data-size":"full","data-attachmentid":3269270}[/ATTACH]

No Its all fixed levels.
There should have been an adjustment in some way.
Any idea what voltages I should be seeing on those chips.
Ill hook up a CD later on to it.
Its either the input or output. Knowing those voltages might help.
Its a shame I cant get the schematic as that would help and we could see the whole thing and how it works.
Like I said I can always use something else but it would be good to try to make it work properly.

Hi
Im on a mac.
Theres no adjustments to make. I was looking for some.
I thought it being USB ,there might be software that accesses a chip in there to adjust it but no.
I need to try a loud CD through it. I'll then know if its the output side.
The owners of Citronic dont have a schematic for it , so how did they make it.
I cant see it being like that from factory. Maybe a component is gone somewhere.
I can always find another way but why not try to get it right if I can.
Its handy as you just plug the turntable straight in.
Here is a better...Leave a comment:

It’s a usb audio interface but you can connect a turntable to it or another audio source.
I’m talking about the input via USB.
It’s too loud for some reason.

Citronic AC-1USB Output Too Loud
Hi
I have a Citronic AC-1USB.
When I run a turntable into it and then try to record it. The volume is too loud and distorting. In the red. Mainly 12” Singles. I haven’t tried a CD into it yet. I’m wondering if there is any way to bring the volume down inside the unit itself. Change a part or two. Put a small pot somewhere as there are no adjustments at all in there. I’m looking for the schematic but not found one yet.
Heres the circuit board inside.
Cheers

I got the Plug for the adaptor at last. A Nice Silver one.
Soldered it all up with Heatshtink included to make it ice and neat.

I plugged it in and hooked it up like a mixer and it works.
Im getting the audio through it.
I'll try a mic later on and mess with the effects a bit.
Ive had it a while and didn't know the adaptor was the wrong one.
Sad really.
Great to see it working like it should...Leave a comment:

Ok man. Thats what I was thinking.
The Unit is all back together now.
I'm still waiting on the plug.Leave a comment:

Im waiting on a plug for the adaptor ,as the one on the end ,don't fit ,as the pin on the device is too big.
One thing I noticed when buying one ,is there are a lot more DC adaptors than AC ones around.
Did you work out why the front panel works with the DC Adaptor.?

The Adaptor should be here next week.
I'll be surprised if it don't work.
Cheers for the help so far.Leave a comment:
