You can do a simple test:
Play some music just connect the source right channel to the preamp and leave the left channel disconnected, if sound come out from both left and right speakers that is the switch position of MONO.
joule la150mkII- preamp
Hi All
this is a stupid question, but i cannot seem to get the answer. i have a joule la150mk II. there is a button for stereo or mono, but nowhere in the manual does it specify whether the button needs to be depressed or not. there a re2 signs next to the button that look like a sideways v. as i said, i know its a stupid question, but if anyone knows , i would deeply appreciate it
thank you
