I have an old Baldwin Professional Amp that I would like to send into the L1 Model I via the external speaker output on the back of the amp. Can someone enlighten me on the best way to do this? My first guess would be to run a speaker cable from the amp into Amp 1. So far this seems very noisy so I'm wondering if I'm doing something wrong. I will probably end up unhooking the actual speaker on the amp and just use the output from the L1. Is there another input that would be more suitable? I also have a T1 tone match but didn't think it would be appropriate to go through that. Any help would be appreciated.

Hello Damon,

NONE of the inputs on any of the L1® Systems or the T1® is designed to accept the powered (speaker) output from an amplifier.

PLEASE DO NOT CONNECT a speaker output from your amplifier to your L1®.

You might be able to make this work if you get a DI box that is designed to accept speaker level inputs and provide a line level output to a mixing board or console.

Here is an example of something that may work.

So would it be best to go external speaker to DI, then to an input on the T1? Is a speaker cable required?

Thanks,

Damon Bramblett

Hi Damon,

I've been searching for information about this and have come up with very little. Certainly not enough to feel comfortable saying anything more specific than:

Try a DI that is capable of accepting speaker level input and outputting a microphone or line/level output.

Use microphone level if you are connecting to an XLR connection on your L1® system or

Use line level if you are connecting to a ¼ inch input on your L1® system.

Yes, you will need some kind of cable from the amplifier to the DI box.

Without being able to find some documentation for the amp, I can't tell you what that cable might be.

Sorry that I can't suggest anything more detailed.

Hey Damon - Could you tell us why you want to use this amp? It might help with the answer. Roy

Looks like a low-impedance transistor output (2 or 4 ohms?) via 1/4in jack. Heres a little info:

Baldwin Professional

and from a link on that forum:

try looking at something like a Palmer PDI-03 or PGA-04, they can take in a power amp output and soak up all the power and then give a line out which you could take to the T1.. I use a PDI-03 from the speaker out of my Amp head into the T1- works a treat.

If you don't want rack mount, I think the THD hotplate also has a line out on it.

good luck.
