Subwoofer hook up

Jimbo18

The Velodyne sub I just got doesn't have a single subwoofer cable hookup like my old one so I was planning to use speaker wires. The manual that came with the sub says to run wires from the surround outputs to the sub and then to the surround speakers.

I read several threads here that mention using the front outputs to the sub and then to the front speakers.

Does it make any difference?

Jimbo18

Doesn't anyone know? If not, I guess I will stick with using the surround outputs like the book says mostly because I run my surround wires behind where the sub is place now anyway.

The CHT-10 has RCA level inputs. Just go sub out from your Pioneer to the LFE input.

Thanks, got it. My eyes ain't what they used to be. Didn't see that one of the inputs is marked that way, I thought it had to have both inputs connected. :redface: And the book didn't mention it.

(Not the first or last "redface" for me I am afraid).

Jimbo18

Actually, I didn't miss anything because it's not there. The sub that I have isn't marked for an LFE like the one pictured above. Guess I am back to asking the question if it matter if I use the surround outputs instead of the front.

Use either of the inputs RCA inputs.

Jimbo-

Habanero is right. Even though your sub does not show the LFE graphic, using either RCA input should work fine. As far as routing speaker wire- I've never heard of using wire from the surrounds. That just doesn't make any sense. I'm not doubting what you are reading in the manual, but sometimes things get screwed up in translation. All the manuals I've seen for Denon AVR's are awful and you need to be a mind reader to figure them out.

Just think about the surrounds only receiving a small portion of the overall sound from a movie mixed in 5.1 channels. Very little LFE effects to be had by sending that signal to the sub. If anything you would use the L and R front speaker wire to sub 1st and then back to the front speakers. Especially if you are listening to a stereo source such as CD's, otherwise you would have no signal going to the sub.

The easiest and most effective method will be to use the subwoofer pre out on you receiver into either rca input on your sub. Good luck getting it going.

From the owners manual:

Subwoofer outputs
The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Many home theater processors/receivers (Dolby Digital, DTS, THX) have a "subwoofer out" jack that is internally filtered and designed to be used with a powered subwoofer.

In these installations, you may bypass the internal crossover in either the processor or the Velodyne subwoofer. In some installations, it may be beneficial to have a steeper ultimate crossover slope. To do this you can use both your processor's crossover and the one internal to the Velodyne sub. You should stagger the frequencies (i.e., 120Hz sub, 80Hz processor) for best results.

To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another crossover, simply locate the switch marked "SUBWOOFER DIRECT/INTERNAL X-OVER" on the rear panel of the subwoofer and set to the "SUBWOOFER DIRECT" position. This will eliminate the internal crossover from the signal path.

Note. . .
If not using an external crossover, you should use the built-in crossover for optimal performance. When using a single channel input signal (such as a surround sound processor's subwoofer out, or LFE), the auto on/off circuit sensitivity will be affected. When one input channel is used instead of two, the unit will see lower signal levels present at the inputs. This may cause the unit to turn off when listening at low volume levels. If this occurs, simply use a "Y" adapter (available from most dealers) to allow your processor's single sub line to be fed into both L&R inputs. This will make the unit turn on at lower signal levels.

In short, use a Y adapter into the inputs. Play around with the SUBWOOFER DIRECT/INTERNAL X-OVER switch and crossover points to see what sounds best.

Thanks, guys. And WLDock that is exactly how my manual reads. I didn't have a Y adapter and thought I would just go with the speaker wires, and somewhere I read that this might produce slightly better signal, but as TNHDYMAN pointed out, I also thought that it didn't make sense to use the surround outputs, that's why I asked the question initially if it mattered using those, or the front, outputs.

I will have to hit up RS or BB I guess for a Y adapter, or just use the front outputs.

Thanks for all the help.

Mono price has really nice and good Y adapters. I bought mine from them.

Jimbo18

Thanks, GFO, will do that.

You don't need a Y adapter. Just hook up to left or right and you'll be fine.

Thanks. And actually, since I don't yet have the adapter, I did just that this morning and then ran the MCACC and it sounds great so far.

The Velodyne definitely digs deeper than the HK did and seems great for HT so far. Not sure about music yet though.
