proper sub setup (1 Viewer)

[john bourne]

Sorry for the simple question here, but I read a lot of technical jargon last night and confused myself silly.

When setting up a sub is it best to:

1. set the gain on the sub amp at 1/3 or 1/2 and make the corrections with the pre/pro

2. set the pre/pro sub level to zero and adjust the gain on the sub amp

3. no difference

I understand to set phase first.

Also do you guys try to match the sub level to your mains or do you run it a bit hot?

Thanks for your input as always.

I say start a point 2.

Some things to think about when setting the pre/pro level though.

Setting this level too high can introduce distortion into the signal so it is best to keep it as low as possible. Any below +5 or +6 is probably ok, but lower the better. However having it it is too low may not trigger the subs auto on circutry, it may need to be turned up to get the sub to do anything. Leaving it a 0 is good because it gives you the most flexability of adjustment, if you need to tweak it up or down depending on the content being played. But still may not have a strong enough signal as stated above.

good point with the auto-on function of the amp - thanks.
