I have a 4100 NEX, when i adjust the equalizer, only the front and rear speakers are affected, not the subwoofer output. It is just me or ?

The subwoofer will be affected as long as the frequencies you're EQing are within the range the subwoofer is allowed to play.

For example, if you have low pass crossed over at 80Hz and you EQ the 63Hz band, the sub will be affected. If you adjusted the 8kHz band, the subwoofer won't be afffectd. Why would it? That wouldn't make sense.

Pionneer just anwsered my question :

"Thank you for contacting Pioneer Electronics (USA) Inc.

You are correct, the EQ does not effect the subwoofer output. This is
normal operation for the NEX series units."

JUp that was good with my AVH-X8500BT. There it was possible to adjust the subwoofer with the equalizer.

Now with the AVIC F70DAB it is not possible. It is a shame for such a price...

It seemed logical that the subwoofer would be affected if you EQ a frequency that the subwoofer plays. I guess the NEX series is designed so that the sub output is completely independent of the EQ? Very interesting...

Yep, i seemed logical. Im a little deceived

Not just logical, but conventional.

Another ill-conceived Pioneer "we think its better this way" idea.

This is about on par with Microsoft Windows Volume Mixer implementation.  On a professional mixer board, you set a channel's volume level (slider) and it stays there when master volume slider is moved.  In Volume Mixer, per application sliders all move in proportion to the "master" and additionally the tool-tip number values are relative to full scale and not the "master" position.  The people that make these decisions and have the weight to actually have them implemented should be fired for false personification of an audio professional..!!!

I'm about a half-notion away from going with another make...
