Hi,

can speaker protector be used for monoblocks?

Is ok to just left out K2 and R12 and just use K1 with appropriate voltage?

Kind regards
Urosh

If you are considering a second run of the 'Soft Start' pcb, could you include a simple DC Trap, as any dc component is 'bad news' (for torroids especially) and is now common in all of our main supplies - just requires a couple of caps and diodes directly in line with the active mains line that's already on the board - plus, while the mains is so readily available, perhaps add a simple 'Line filter' to complete the set.

Yes it will work. Yes again.

Hello,

If I want to use DC voltage :
- I don't need C6 and I can use a strap instead of D6,
- I must use K1-1 as the positiv and K2 for ground

Is that right ?

I have 12volts relays, what range of DC voltage can I use ?
How much current do I need ?

Thank You for your response.

If you have available 12V to 15V DC then you don't need D6 and C6, but be mindful of the polarity when you do. Make sure the positive goes to the line going to D6 position. 500mA to 750mA should be more than enough.

I'm not sure what you mean by "I must use K1-1 as the positiv and K2 for ground"

Sorry, I wanted to say : connect the positiv DC (12V to 15V) to X1-1 and connect the ground to X1-2.
Thank-You.

Yes that should work. But if your relays are rated 12V then you need 24V DC supply, not 12V-15V only as the relays will not engage.
