Shur Iso Line out...

[lespaul6]

Anybody using one of these boxes for a wet/dry set up? Can you leave your head connected to your speaker cabinet and just use the other speaker output jack for the iso box without changing the ohm setting on the amp???
I don't want anything between my head and the cab so if this cant be done, I will not be using it.

Yes, that is the way I ran mine...

I think it can work this way? I run mine in between the cab and the head and then out to my SDE3000 to the Matrix power amp to the 2X12 Dr Z cab. It does not alter the tone that I am amare of?


Per Suhr:

The ISO Line Out box is used to provide a transformer-isolated signal from any guitar amplifier speaker ouput jack. One common purpose is to provide a line level signal that feeds an effect processor. The wet only output of the effect can feed another amps effect loop return or power amp with speakers to have a Dry/Wet setup or even Wet/Dry/Wet.

What it is NOT:
The ISO Line Out box is NOT a load box. In other words, the amplifier MUST have a speaker connected at all times. The ISO Line Out box is not a speaker cabinet emulator.

Connect any available speaker output jack to one of the Speaker Thru jacks on the ISO Line Out box. If the amp has only one speaker output jack, connect this to one of the Speaker Thru jacks on the ISO Line Out box and plug the speaker into the other Speaker Thru jack. Connect the Line Out jack to a balanced or unbalanced jack of your mixer, effect or recording device. Set the appropriate level.

cool... thanks for the replies guys. Looking to go this route rather than have a slave out added to the amp.

I disagree. Reading the material it states the Iso line out is not a load box which means the amp must still see a load of some sort, such as a speaker or load box. Looking at the Iso box, the notations show the speaker load is a straight through process with a line taken from it.

What you can do is run the Iso box between your amp and cab with the line out to another amp or effects, but not from a separate ohms tap.

Quite sure its a high impedance box, mine is not a sure but I use it in a separate output. Mine is not a Suhr but I think is very similar.

I've used one for having my main amp dry and used the ISO to run my signal to effects then out to two Tech 21 Power Engines in stereo..... it worked very well.

BTW it is NOT a load.

this is kinda what I'm getting at... I realize it is not a load. So, I have my head plugged into my 4/12 cab as I normally do at 16ohms ... this would be my dry tone. Can I then use the amps remaining speaker jack to steal a line level signal using the iso box and into effects then power amp?

You use two speaker cables and a regular cable. You use one speaker cable out of your speaker output on your amp into one of the "speaker thru" jacks on the ISO then use another speaker cable plugged into the other "speaker thru" jacks on the ISO then into your 4x12 cab. Then use the regular cable plugged into the "line out" on the ISO to go to your effects then out of your effects into another power amp and cab. That would give you a W/D set up. Of course if you use a stereo power amp and two cabs after your effects then you would have W/D/W

This is how I run my W/D set-up.

ok then, I think I will hold off as I did not want anything in between my head and cab... I know is "transparent" or whatever but I'm weird about hearing differences, high end roll off..whatevers... I'll hear it!

In reality that doesn't play out but sounds like you've convinced yourself you will... so.

I agree!!!

 

[lespaul6]

lol.... yes, Ive had bad experiences will most things labeled "transparent".

 

[MrDan666]

When it's hooked up, there is absolutely nothing between your head and cab. The speaker thru jacks on the Suhr box are wired together in parallel, exactly the same way your amp's speaker jacks are wired together.

It can't have any effect on the amp's tone whatsoever

I think some folks need to reread this thread and the manual.

OP: the manual clearly says you can use any available speaker jack to tap the line out. If your amp has only one, you have to insert the ISO box between the amp and the cab. But if you have more than one (which you do), you run one directly to the speaker and the other to the ISO box.

If you're really in doubt, you can call Suhr, but I don't see any other plausible interpretation of that manual.

 

[metalmaniac93]

Well I have one and use it with the Atomica running W/D and there is no transparency issues. Suhr pedals, electronics are amazing. Same goes for the Koko Boost.

 

[lespaul6]

Above, that is how I read it initially as well and just sought confirmation from someone here who might be using it that way. If it is as you and I assume then that would work for me.

How about setting it up like I described? can you give that a whirl and report back

With running it in between the amp and cab, I'd be less concerned about loss of tone and more concerned that somehow one of the speaker cables gets unplugged or the box breaks somehow leaving the amp without a load. Much safer to run it off one of the other taps.
