That's all news to me. Mine doesn't have line out, only DI. . afaik, which isn't very much, unless the amp gets driven it won't heat up. When working hard to drive speakers it gets hot, but not when it's idling.

A line out should be the preamp signal on full bore anyway, not dependent of the amp attenuator. If it really is dependent on the attenuator then TBP player is probably right and the amp will be disconnected when the line out is in operation. The pdf should spell that out without any guessowrk required.

Hey guys, just wondering, what exactly is the point of the ground(earth) lift switch on most(all?) TE amps?

Looking it up it seems like it gets rid of hum from ground loops?
I kind of understand what that means, but my real question is this:

If it helps your sound, why give the option to turn it off?? :p

cheers guys :)

When two or more devices are connected to a common ground through different paths (Preamp Ground and Power Amp Ground), a ground loop occurs.
Currents flow through these multiple paths and can develop voltages which can cause damage, noise or 50Hz/60Hz hum in audio or video equipment. To prevent ground loops, all signal grounds need to go to one common point and when two grounding points cannot be avoided, one side must isolate the signal and grounds from the other. Lifting either the Preamp or the Power Amp ground eliminates the loop. See?

Thus, Trace Elliot has provided a way to isolate the signal section from ground while maintaining a "Chassis Ground" so you don't get the S^&! shocked out of you when you touch you pre or power amp :D... for safety reasons...

It's in every Trace Elliot manual for equipment that has this feature.
Not all manufacturers provide a ground lift, thus making it more difficult to isolate HUM and other noise in the signal which gets amplified and sent to your speakers as NOISE. :spit:

If you are only using the AH or RAH, which all have an internal power amp, the signal section needs to be grounded so you don't hear any "noise".
When you connect it to another power amp via the DI or Line Out, you need to lift the signal section ground to isolate the ground loop - so you don't hear any "noise" - created by a ground loop.
Confusing, aye? :eyebrow:
So they give you an internal switch to do it without having to BUY an external ground loop isolator.

Well I stumbled onto a really cheap ($150) 1153T cabinet a couple of weeks ago and almost immediately started looking for a second. I really could not believe how much I liked it. Well a fellow TB'er, Count Bassie, helped me out so here is my current rig: Ampeg V4 feeding two 1153T cabs - one for small gigs, two for when one is not enough! Sounds great with my Fender Deluxe!

This is my first ever Trace stuff and I must confess that they make some pretty fine stuff. I guess I am now a member of Team Trace!

Thanks Trace! really helpful :) Sorry i didn't see the manual, i bought my amp second hand :p

Just one more question:
Is there any disadvantage to leaving the ground lifted when you don't need to?

Hmmm.. I answered this earlier but I don't see my post....:confused:

So,....
No advantage to leaving it lifted.
If you are NOT using a secondary power amp, TE manuals say it must be grounded. It helps to send errant signals, noise and RF signals to ground instead of to your speakers - hum, noise, 2way radio transmissions can get in to the system...:mad:
I have several model manuals if you need one PM me your email and model - I'll send you one in .PDF (adobe).:D

Hey guys, not sure if this is a good place for this post, but I came across this TE 4x10 cab on craigslist and was wondering if you think it looks like a good deal or no? I don't know very much about these cabs so any insight would be appreciated.
