A question about Jadis's integrated amp's selector

I got a 2nd hand Jadis DA50s integrated amp last week.

I connected the amp with a cd player.
The amp worked fine when I switched the selector to "CD".

But when I switched the selector from "CD" to "tuner" or "AUX", I could still hear music at low sound level, when I set the volume knob to mid level.

Is it normal? Is there anything wrong with my amp?

It is normal. You experienced a phenomenon called "crosstalk".

thx, Njkoh

One more question,

I just studied from the user manual, knowing that the amp's load impedance is pre-adjusted for loudspeakers from 4 to 6 ohms. But I am using speakers with 8 ohms.

Should I made an internal adjustment as the manual said (http://www.hkbizz.com/photo/albums/userpics/10001/Image0002.BMP)?

What are the three pictures showing?

thx so much
