I just checked my user manual and sales brochure and they both say the same as what you have. Seems a bit odd that power would be the same for 4 or 8 ohms. I will check my DC at the speaker outs and post them later tonight.1st page has wrong specs. It mentions 120 w for both 8 and 4 ohms. So either it's same for both loads or it's a typo.
