dangerous to use the VH4S in mono?

[loic]

If i use my VH4S in mono, there is a danger on the unused side?

If i turn down the unused side, is it enough to protect the amp?

You probably want to make sure there is a load on the amp, even if no volume is being used on that side, unless either Peter or the manual says otherwise...

I believe you can not do this. You have two tube amps in one, when the stand by is flipped off you should have BOTH amps plugged into a load. That is the drawback of the VH4s, you HAVE to have a stereo cab to plug BOTH sides into ALWAYS.

 

[~Abstract~]

Once you turn the amp off standby...even if it's turned down...BOTH SIDES need a reactive load (aka speaker...load box...SOMETHING). DO NOT just leave one side unplugged. You will fry your output transformer doing that.

DANGER!

me too, i think that's dangerous... but it seems that Peter had already told me that's not dangerous ... but i'm not sure

I have two stereo cabs, but sometimes i don't play with my cabinet on stage and i have to play in mono. I will buy a torpedo live very soon and i have to use it in mono .... So i have to know if it's safe for my stereo toy

Sounds like you need to buy an attenuator to use just as a dummy load box to properly shut down one side of the amp, or you might want to consider selling/trading it for a VH4.

Indeed I often think to trade my VH4S for a VH4 ^^

this load box is a solution but it's expansive and big : http://www.palmer-germany.com/mi/en/PLB ... PLB2X8.htm

Do you know a smaller load box?

This is all you need plus a jack and some speaker cable:

The shop also has small enclosures, add that and a jack to your list and drill a 11.5mm into the enclosure . . .
