I also have some spares, from our recently finished UGS project + UGS Motherboard

I intend to use the Joshua Tree attenuator from twistepearaudio.com in front of the UGS pre. The standard resistor set that can be bought together with the attenuator gives an input impedance between 2,2 kohm and 10 kohm and an output impedance of 750 ohm. I bought the attenuator boards without any parts so I am free to chose the resistors to suit my needs. I am a little worried that 2,2 kohm would be a little low at the input of a pre. What do you think? Should I go for a little higher impedance?

You can keep the existing resistor values you have, and by placing attenuator at the output it would likely work and would be a better match; UGS won't mind the varying impedance of the ladder. A 10k fixed ladder might be a better solution at the output though. UGS out impedance is about 125 ohms single ended and 250 ohm differential. Best, nAr

I will start with these boards since I already have them but later I may try a 10K ladder as well. Thanks for the answer. |

For ladder at the input input I mounted two of those for balanced operation in stereo, so far so good ![]() http://www.audiophonics.fr/potentiom...0k-p-5228.html Best, nAr
