Hartke LH500 Effects Send volume

The master volume control or the gain knob? Usually the master won't affect volume but the gain will.

 

Weird. Well I don't know but Hartke CS is excellent. If you can wait till Monday, I'm sure they can help but you'll probably get an answer here soon enough.

 

Question, why are you using the effects send and not the DI?

But you’re right right the volume controlling the effect loop shouldn’t happen.

 

That’s what most folk want to go into their recording train.

 

Blech!!!

 

That's not really how the LH works. If you plug into the FX return with any pre-amp, The volume knob is deactivated. Edit: This is because you would be bypassing the Entire preamp section.

The send side of the effects loop has to be responsive to volume knob. Or you'd have no volume since the signal goes through the effects loop.

Edit: It almost seems like that part of the manual is just wrong.
This one line in particular:

"post-EQ and post-Limiter but unaffected by the setting of the VOLUME" control.

 

I just helped somebody with something similar using a preamp pedal... the effects send is POST volume control, post EQ, and the effects return injects signal into the power amp with no additional volume control. It's possible that there's just a mistake in the manual. (at least on the unit that helped a player configure with his preamp)

 

Yeah I think it’s likely that there’s an error in the manual. Maybe they copy/pasted some parts from another bass amp manual that had a separate gain and master and didn’t consult the actual schematic.

 

I had an LH1000 and I can confirm what the OP is experiencing with the fx loop. The loop should be labeled pre out/power amp in instead of fx loop.

 

It's no different than most effects loops on amps without a master volume control.

 

Wait. So I'm confused. If I had a pedal board with preamp and plugged directly into the effects return, the volume control on the amp doesn't work? All volume would be controlled from the pedal board going into the amp?

 

Correct.

 

Well this thread and information is surely timely. I've got just that type of set up and have been running into the effects return of an Orange TB500 and I was feeling bad about using it all the time and was thinking of picking up an LH500 but I would need the volume knob on the amp to work (it works on the Orange). Thanks!

 

You are essentially just using the power amp section and bypassing your amps pre-amp when plugged directly into the effects return. It's cool to try different Pre's or pedals this way. There's a whole new selection of tones for better or possibly worse.

 

The TB500 must be wired in a unique way. At least not like Hartke. Does the EQ section work also?

Edit: actually, looking at the Schematic it looks like EQ section would be separate.

 

Eq is before the effects loop.
