Laptop headphone out causes wierd 2x4HD effect

[Cornell Smith]

This has me stumped. New 2x4 had no output on channels 2 and 4, regardless of routing- as long as either input was connected to either headphone output. Without changing anything other than the 2x4's input, all 4 channels operate normally. I was using the generator function to set up subs.
I'm loading the software on another laptop.

What type of headphone connector are you plugging into the laptop? Is it a 3-conductor TRS male connector, or is it a 4-conductor TRRS male connector? The 4-conductor male connector is meant for use with smartphones and includes a contact for a mic connection. The 3-conductor male connector is for regular headphone jack like most laptops have and includes no mic connection. A 4-conductor plug (male) mated with a 3-conductor jack (female) gives an iffy connection and results that can sound extremely weird. Just a possibility.

No. It was a case of operator error. I had neglected to set the crossovers to ‘bypass ‘. No worries.

Glad you got it figured out.
