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,
