Hi,

my test with http://www.tfm.ro/win32-projects/test-avi-ac3/

Since I have no SUB connected to my AMP I connected my front left speaker to the sub output. With the test sample I could hear the LFE test tone. So, one is able to hear the sub channel on my front speaker. This is my first observation.

Now my tests:
  1. L/R: Large or Small // Center: off // SL/SR: off // RL/RR: off // Sub: on
    1. SL/SR and Center are mixed to L/R
    2. Sub test tone can be heard
  2. L/R: Large or Small // Center: off // SL/SR: off // RL/RR: off // Sub: off
    1. SL/SR and Center are mixed to L/R
    2. Sub output is silent (well, it's off), but Sub test tone is not mixed to L/R
  3. L/R: Large or Small // Center: off // SL/SR: Large or Small // RL/RR: off // Sub: off
    1. Center is mixed to L/R
    2. Sub output is silent (well, it's off), but Sub test tone is not mixed to L/R
  4. L/R: Large or Small // Center: Large or Small // SL/SR: Large or Small // RL/RR: off // Sub: off
    1. Sub output is silent (well, it's off), but Sub test tone is not mixed to L/R

My conclusions:
  • center is mixed correctly to L/R
  • SL/SR is mixed correctly to L/R
  • Sub is NEVER mixed to L/R

Test were done with firmware 1.61.

Question to the other testers:

Did the mix-up of the sub to L/R worked in the past with any firmware? For example, 1.56?
