Int. Amp's input sensitivity and DAC's output

Hi,

I'm a little confused (concerned) about the match between my Cambridge Audio DACMagic and my integrated amp. The DACMagic's output is rated at 2.1V rms (unbalanced). My integrated's line input's sensitivity is rated >= 200mV and overload signal level rated >=2V. Now I'm concerned that the DAC is actually driving the pre-amp section of the integrated to overloading levels.

Is this a correct analogy or am I mistaken?

Comments appreciated.

Thank you Atmasphere, well I'm using DK Design MKII, I'm using an external Phono Preamp. The thing that bothers me is the Overload signal level on the amp which is rated at 2V (or greater) and the DAC's output is rated at 2.1Vrms.

And yes you're correct, with CD I'm always at the bottom of the volume control

I would purchase attenuators with RCA plugs that would possibly increase ranges on your volume knob and dynanic headroom of the system.
They're available at partsexpress.com.

Thank you Maraknetz, any chance of signal degradation?

The Rothwell 10 dB in-line RCA attenuators were, to my ears, more transparent than the partsexpress units. they do cost quite a bit more but there are significant benefits from operating your system w the volume control more in the middle of its range.
