[Bug] Low output signal/power with bass shakers using custom channel maps - Please close...shakers were cancelling each other out.

[jblondin1]

Describe the bug

I have 4 corner bass shakers installed, using two aiyami a07 amps connected to a usb 7.1 sound card. I have configured all outputs, and can send test signals to each corner without issue. However, when I set an effect like "gear shift" to all 4 corners the power output is significantly diminished to the shakers. If I do front left and rear left, its very strong, nice feel, but as soon as I pick front right and left, the power is diminshed significantly. I have tested the amp using much lower power shakers as well, and same issue. Its not an amp cut out, or frequency issue.

SimHub version

9.11.21

Third-party plugins

• I have disabled all third-party plugins.

Steps to reproduce

shake it bass shakers, sound output, "custom channel map". Select left and right front as output for "gear shift". Test.

Repeat above steps and only select Left output, retest.

Expected behavior

I would expect that I can send effects to any channel I wish without diminished power or response. Something is lowering the gain behind the scenes when I output to LH and RH shakers.

Please close this ticket...come to find out...my shakers are opposing and just canceling each other out in stereo. I need to dust off my physics book. All good now. Thanks
