Default Output from FM tuner too high level

Hi

I have a wonderful FM tuner (Micromega with fixed output level) and an Audiolab 8000S integrated amp. The output from the tuner is very loud, I have to turn the volume to 7, almost entirely down, and it is still very loud.
Can I make a voltage divider with some resistors soldered into the RCA plugs? I do not want to mod the tuner or the amp, that fits well with my CDP as to volume.

Which resistor values to use?? Any other suggestions?

http://www.rothwellaudioproducts.co....tenuators.html claim to have the solution, but at 39/pair.

These RCA plugs contain resistors coupled as voltage (potential) dividers, as I suggest to do myself. But what about the values, and does the resistor to ground go from the "sending" or "receiving" end of the series resistor??

You should make it yourself!
For tips, see here: http://www.goldpt.com/pre.html
the pre-attenuation you could fit inside a plug, or on the inside of the amp.

just to be sure...you have not connected it to TU-rntable-input?

Making fun with me?

No, there is no turntable input on an Audiolab 8000S, only linear inputs.

Hi,
I am surprised that the Tuner & 8000S are not compatible.
The 8000S should need more gain to play the tuner than the CDP.

Can you measure the output of the tuner with a DMM?

If the tuner is putting out more than about 200mV average then consider an attenuator built inside an RCA phono plug (at the 8000S amp end). It is only two resistors for each channel.
