Leach Amp protection quistion

lykkedk · 15th December 2003, 06:11 PM

Hi. I was woundering if anyone could tell me, if it's safe to cut the +out at my Leach amp. ?

The reason i am asking, is that I just finished my BoSoZ, which i connect so i only have one power switch to turn on, so that when I turn on my Pre-amp (BoSoZ) it's automatically turn's on my power-Leach amp!

I bough the Velleman p4700 loundspeaker protection kit, which give's me, what i want, when turning it on, it make's a deley at about 6 sec. which is supposed to be connected through the loudspeaker +out, so that i would get no turn on thumb, and when turning the power off, it should cut the +out immidiatly.

But I was woundering if it's safe to just cut the +out-loudspeaker connection's and whether it should be done before the R50, C25 connection, or directly at the output?

The output look's like this :

o Speaker out
|
|
o-------------------o +
|
R 10ohm
|
Cap 100nF
|
o-------------------o -
|
|
o GND

Easiest to insert in the wires to the terminals IMO.
Can't see any problem with this.
