Will this work? - Connection question

My newly acquired Rotel RA-02 integrated does not have a sub-out. It does, however, have pre-outs for L/R, which I'll be running ICs to my Rotel RB-1070.

I would like to run a sub with this rig, and I understand I can use the speaker level inputs/outputs on the sub to connect. I'd rather not have all the speaker wire running all over the place.

What I was thinking is running a Y adapter (MFF) from one of the pre-outs, and connecting the sub to this Y.

This *should* work, since the low frequency signals are basically mono, right?

I have a similar setup....my integrated has pre-outs which run to the sub.

Don't forget, that with this setup and NO external x-over, your 'mains' will still run full range.
At hi amplitudes, with lots of bass content you could still overdrive the mains without the sub even breaking a sweat.

Cool. Thanks Jan.

Leo, I'm not worried about my mains running full range, they dip down to about 35 hz, I believe and have the x-over on the sub set as low as it can go.

Bingo!
My panels go to a claimed 36hz, I have the X-over on my HSU set to about 40 hz and I have bass that'll rattle your fillings.
Very seamless, good for music or HT.

My sub is nowhere as nice sounding as a Hsu. But it goes boom, sometimes almost musically.

I think my next sub (for my dedicated music system) will be a Totem. Something small, fast and musical.

Yup. It works (not that I had any doubt).

Hooked up my new RA-02 last night and used a Y-connector out of one the RCA-outs.

Silly question, perhaps, but will this affect the balance of the system in anyway? Having one channel split by a Y connector, and not the other?

Your sub has but one RCA connector?

The sub has 2 RCA inputs. I was talking about my pre-amp. It has no sub pre-out, so I'm using a Y splitter on one of the pre-outs.

You should be splitting both pre outs.

That's what I figured.

Just out of curiosity, what kind of effect is this having on my system?

Bass....more bass.
You MAY experience other symptoms. Less sleep. Nausia in the morning, at least until your second cup of coffee.

hehehe...the 2 channel input to the sub will mean 3db increase in sound, Daviv, along with ant 'non mono' stuff that you will see from the upper roll-off.

Go stereo cables.

Juuuuust cause you can.

Will do Nuck.

3db is nothing to sneeze at. And I like buying cables...
