REL sub setup

I'm not sure because it's not in front of me, but I think there's a knob with numbers 1-4. In the manual it says they are high pass 0 phase, high pass 180 phase, low pass 0 phase and low pass 180 phase. At least this is what I think it is. I have mine set to high pass 0 phase. If I'm not totally making this up, why would the sub have this switch if it auto detected? I guess maybe I should call REL...

Correct me if I'm wrong Jrwr7, but those independant knobs allow you to set the phase control for the different inputs independently, so when it auto switches inputs, the phase is customized for that input; you may want the phase setting different for movies than music.

Hey Y'all,

I've read the manual and on page five it explains the functions of the mode selector. I have my subs set to 4, meaning the phase is set to 180' and I have the LFE signal by-passing the ABC filter in the subs because I have my processor handling the crossover, thus giving the subs only the signal they need to reproduce through the RCA cable connection. The line level signal would need to go through the ABC to blend the frequencies properly with the speakers. The subs are receiving a full spectrum signal straight from the amp, through the Nutrik cable, so the ABC would filter out everything above the frequencies the sub is set to reproduce. I had to read the manual about four times before I felt I had it correct. I hope this clears things up.......John

The mode switch may not actually be the input selector. It sounds like you still need to change the mode switch position when going from the hi level input source for music to the lo level input from the HT source. The advantage is you don't need to swap connections going from one source to the other. Since I only use the Stadium III for music, it has not been a feature I use.

Hey Y'all,

Eagle, I'm 100% sure you do not need to change the mode selector for H/T to music if you are using both the Nutrik cable and an RCA connection simultaneously. The only thing you’re doing by changing the mode is adding/subtracting the ABC filter and possibly changing the phase setting. As I mentioned above, what the ABC does is affect the subs crossover frequency internally. That is how the sub takes the full range signal directly from the amp, via the Nutrik cable, and blends it with the sound from the main speakers in 2 CH play back. If you use the ABC for H/T it defeats the bass management in your H/T processor/receiver. The only reason you may need to switch the mode is if you do not have bass management in your processor/receiver, but most units now include this function, especially for H/T.

I've also found that once you find which phase setting sounds good for your room, it will work for either H/T or music.
