One dedicated circuit for each mono block?


If I have a dedicated 20 amp Circuit is that ok for two monoblocs? I read that a separate dedicated line is better for each amplifier. So the outlet can't have two plugs but it's better to not use one of the two plugs when connecting a mono block?

I have a transparent Power isolator which I know use to plug amps into.

So maybe a dedicated circuit can be used to plug amps directly into and then have Power isolator connected to a separate Circuit for everything else.

I am trying to evaluate the merits and to need for getting a second dedicated line while installing the first.

One will be fine

 

have monoblocks on one line all the time

unless you have Krell mastercllaasss, you will be good. 

Good point @arcticdeth  Yes.  I have Krell KRS200 references from late 80s, upgraded to 400w per side.  They can draw up to 2kW a side.  Watch the house lights dim when they power up.  No arctic deth in my listening room!

I run each off a separate circuit.  I also run three more circuits for TT, pre-amp and phono amp.  CD player and SACD player, have their own circuit - don't want those ugly digits escaping anywhere.

One dedicated breaker, #10x4 line, one leg to a dedicated 9’ copper earth ground stake and the other end to the amp chassis. 
 

Both amps  to the same receptacle.  Use a hospital grade 20 amp receptacle. They are sturdier.

hey, if have the coin, heck yes, do it,!

I thought about it, didn’t have the flow of cash, as I estimated. 
 

 Sounds great! Enjoy

Cashflow is of course a relative thing but, looking at the cost of big Class A amps new today, the KRS200s are great value.  There is a fairly ready supply at between £6k - £12k.  They are nearly 35 years old now so expect service issues.  I bought mine in the early 90s from a Krell dealer ex-dem.  I paid £7.5k then.  About 12 years ago I had them checked over, serviced and fully re-capped.  That cost £3.5k then.  But for £12k today expect them serviced and re-capped.

I reckon that's value and they sound great against today's big designs, many of which have been toned down for the green lobby and don't run in pure Class A right up to the top.  And don't they look the business!!
