Sound gets ONKYO TX-NR609

[HeardThatSound]

Hello, I'm new to the forum. I started looking for answers to my problem and found audioholics. I've tried searching the forum, but couldn't find any related topics to my problem.. see below.

My equipment: Onkyo 7.1 AV receiver (TX-NR609) and some Klipsch Reference & Icon speakers. I have a pair of front Klipsch tall standing speakers (KF-28), a Klipsch center (RC-42 II), and a pair of surround Klipsch Speakers (RB-51).

Problem: When I change the listening mode from "theater dimensional" to "stereo" (using the 2 front speakers only) on the AV receiver, I noticed the sound is so much louder, more bass, and just overall, punchy and better sounding. When I turn "theater dimensional" back on, it seems that the sound gets quite faint, it sounds good, but way less bass, and sounds weak.

Why is this? I've checked the speaker wiring and everything is lined up perfectly; nothing is connected improperly, to my knowledge.


Thanks in advance for any help!

"Theater Dimensional" on Onkyo's receivers is a DSP (Digital Signal Processing) program that adds a bunch of reverb and out of phase information into the audio in order to try and make your room seem "bigger".

I personally do not like any DSP sound modes. I much prefer to use only the necessary decoder, and perhaps either Dolby Pro Logic, THX Music Mode, or DTS Neo:X to expand soundtracks to make use of all available speakers.

Try "Straight" for the most faithful sound reproduction to the original signal.

I think FirstReflection means either "pure" or "direct" when he says "straight"

What exactly is your goal when using only 2 channels? Theater Dimensional is for when you only have two speakers and you want it to sound more "surround like". You obviously have more than 2, so it doesn't really make sense to ever use T-D.

It can also be used with more than 2 speakers, but the point is to get a bigger wider sound out of fewer speakers.

Thanks for the replies!
I was really hoping to get the big sound for music using all of the speakers (using All channel Stereo mode) and have that deep sound that I would normally only hear in 2-channel stereo mode, where only my Klipsch Tower speakers are working. Basically, I like how the sound is booming when it's 2-channel stereo (2 front speakers only), but I would like to turn on the rest of the speakers and still have it sound just as good. When I enable the other speakers (surround and center) using All Channel Stereo, this huge sound fades and sounds somewhat weak. I'm hoping to find a way to have all of the speakers on for music and still have it rockin. I hope this makes sense. haha.
