Connecting P50sa - problems...

[Anesthetise]

It's still quite early, so my mind should be clear, but after 45 minutes of cable switching I'm quite confused...
I just received my P50sa pre amp and I tried to connect it. I have a DAC, plugged it to 'CD' input. The selector is on CD, and only left speaker is playing. When I turn the switch on other positions (tape, tuner, aux), nothing comes out of the speakers. I tried switching the cables between inputs and in all cases only one of speakers is playing, either right or left.
The only working position for both speakers is this one, while selector is on Tuner (sorry for bad quality pic):


There are two options: either I'm silly, or it's broken, but how is that even possible

Hi Anesthetise plug the red and black from your Dac! into the red and black of the aux phono's just below Direct set the p50's selector dial to Aux then anything plugged into the dac will play through the Aux ! then anything else cd / tuner etc applies to the relevant switching

Is this a new P50SA?

Looks like you have SP or SSP between pre and amps. Resist moving that until absolutely necessary (look for the Docs guidance on that). However, since you have both channels working, the problem appears to be before that.
Does the DAC have volume control? Have you tried going to the direct input (which should bypass the preamp attenuator.
Hold the P50 steady when pulling the cables so as not to strain the SSP.

Why did you connect inputs like on photo.? It is wrong. Does it play correct that way?
If you have got build in volume knobs in A80s, you double volume control with P50sa. It is strange, if you use only DAC.

Nope it just dont look right.......................

[Anesthetise]

O lol, that is quite... Unexpected Don't say I have to send back my A80s I need a pre amp.

It's a second hand pre amp.

[fafarskid]

If you like connect more then one source, you need sources switch. You can use P50sa as switch, but you have double volume pots in the signal way.

Looking on the picture from the left, you've got pairs of inputs red (right) and black (left). One pair is for one switch connection named above each pair.
Second hand means someone used it and should work correct.
