Hacking a Luxman Integrated

One cool and often under appreciated feature in Luxman integrateds is the "Separate" button. It disconnects the preamp from the amplifier, allowing for a number of approaches. Actually this is two features. One is the always active preamp output available on the back.

The second is the ability to feed the amp directly, bypassing everything in the preamp. Useful features:
  • Add room correction/EQ/active crossover in the middle.
  • Passively bi-amp (without using separate)
  • Feed a subwoofer (without using separate)
  • Use amp for home theater
  • Use ~ 0.047uF cap to add a high pass to your Luxman, letting you feed a sub for everything below 80 Hz.
  • Use ~ 1uF or higher to add some flavor to the sound. 
It has me thinking about using it with my sub for 2 channel again. :)


Best,

I love the Separates mode.  I have my Marantz 8805 connected to the 509X for L/R and another amp driving my center channel.  I switch to full integrated mode when using my DAC. Awesome combination.
 
I do have a question, are the two sides (amp/preamp) operating completely independently?

When I have the 509X in separates mode and just using the amp side, the sound cut out briefly when I change things on the preamp side.  I could swear this is a new occurrence.  When I used to change the input or Line Straight mode, the amp side was not effected.  Are you guys seeing this too?
