Gain Setting Question...(Yes I Read The Tutorial)

[walkychalky 10+ year member]

so i have a 4 channel amp that is powering my 2 sets of components......its rated 150 x4 @ 4 ohms....so i assume since i have one speaker/tweeter connected to each channel that is what it's running in. SO therefore i am looking for ~49v correct?

Now do i need to disconnect all speakers when setting the gain with my 1 Khz tone?....or just one so i can out my DMM into the + & - ?

Also, for my orion 2500d running @ 1 ohm (2500 watts)....i am looking for 50v correct? ........and should i use a 50Hz test tone or 45?.....i have seen both in different tutorials

thanx for the help

How many gain controls do you have on the 4 channel amp? And as for the orion, that is correct, and use either one, i personally used a 45, but i dont think it makes much of a difference.

For the 4 channel you are looking for 24.49v per channel. Set the DMM on AC voltage and set the gain to 24.49 using one channel at a time 1khz tone. For the 2500d use either tone. It wont change much.

You should, just in case you set the gain too high, so you don't damage your speakers while you do it.

You dont have to. But believe me 1khz at 150rms isnt going to feel nice on your ears //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
