Hallo, I have an old amp without a sub preout. I need to add an active subwoofer. If I use a "double Y cable " to obtain another pre out the speakers level will go down ?Are there other problem to know? I'm sorry for my English, ciao a tutti, Fabio.

I wouldn't think there would be a problem using a y output on the pre out. It would depend on the input impedance of the sub input, but I think it should be high enough to not have any noticable effect. Another possibility would be to use the speaker level inputs on your sub if it has them.Emotiva UPA-700 Amp

Ciao, I think , for example: I have a battery 12volt 3ampere. If I add to much lamps something will go down , right ? Is It the same for the preamp ?Ciao,Fabio.Comment

Good example, but it would be like adding lamps that only draw .003 amps, you can add quite a few before they have a noticable effect. A powered sub shouldn't draw very much from the pre-out. It will take a very small signal and amplify it using the mains voltage in for it's power source. Like using your 12v battery to power a relay which in turn switches on a monster lamp powered by a 220V input.Emotiva UPA-700 Amp

Yes the "Powered Sub" will be in essence doing all the dirty work. The receiver will only sending the sub a signal............ kinda passive or say unpowered if you may, so there shouldn't be any noticable load on the reciever at all.CLIVE

I have always heard (and read) that there will be signal loss when using a y-adapter for this purpose.Comment

I built a new sonosub and I am driving it with an Behringer EP2500. I was thinking of reconnecting my old Velodyne with the new sub. Can I just use a y-adapter to add the old sub. How does this effect the sub output signal to each sub. Also, does this put extra stress on the subwoofer preamp output?... -
I'm hoping someone can help me out. I'm contemplating getting a Rotel RSP 1582 preamp that has XLR outs so that I can connect my preamp to my amp using XLR's (balanced connection). Would it be possible to use RCA (unbalanced) out to connect my sub, a Vandersteen V2W, while at the same time connecting... -
Hello,
I built a new sub which uses a pro amplifier. I decided I wanted to reconnect my old Velodyne sub back up as well to improve headroom. I used a y-adapter at the input of the proamp to daisy chain over to the old sub.
When I first turned everything back on I was... -
Hi,
It was suggested to me by one of my sources that the DSP EPROM update in the latest RSP-1098 firmware release (plus the native EPROM code in the RSP-1068 and RSX-1067) fixed the issue that many of us RSP-1098 owners had with the Sub level in the Test Tone menu being 10 dB too low... -
So I had this old Yamaha sub... 8" driver, 3" x 6" port, about .75 cu ft, with a 50 watt (claimed) plate amp... it sucked. Distorted at the slightest provocation, and overall had all the sonic glory of a wet fart.
The good thing about it is that it was a nicely constructed...
