Connecting monoblock tube amps to single subwoofer.
Hi all,
I have added a REL5TX sub to my system which is driven by VTL225 monoblocks.Currently the sub and amps are connected via the low level outputs on my preamp. I would prefer to use the high level connection to the REL by direct connection to the the VTLs. I am concerned about creation of a ground loop that will cause hum on the system. I have been told that the ground loop can be avoided by running a ground wire directly between each amp. Is this a possible solution, and if so, where / how should the ground "jumper" be connected to each monoblock?
Many thanks in advance for any comments or suggestions.
When I was running a pair of mono tube amps, the tech I contacted at REL was adamant that I run my single T5 in mono, from a single amp only. The red and yellow wire twisted together and attached to the 8-ohm speaker tap and the black wire to the ground. I saw no reason to go against his instructions. I figured REL knows their products a lot better than I do. :). |

@ ieales: Possibly.
*********** Oh no sir, Not "possibly" but absolutely. I can assure you that REL does indeed know their product a lot better than I do. :) One more thought which has usually served me well is to apply the principle of Occam's Razor. I paraphrase: "Generally the simplest answer is the best answer." Not always. of course, but often enough. YMMV. :) And of course, some anal-obsessive audiophiles are likely to surely disagree. :) OTOH, I'm with daveyf, I eventually got a second sub, even before swapping my mono tube amps for a tube integrated. |
