Question about BeePre2 300B Preamplifier

[tube747]

What is the output impedance of BeePre2 300B Preamplifier?

As I want to use in my own system that has active subwoofer with input impedance of 12K ohm.

Whether the BeePre2 able to handle load impedance of 10K?

Thanks!

It's about 3K ohms in the basic form and about 400 ohms at the RCA  output with the output upgrade added. Either version should be fine with a 12K ohm load.

Hi!
I have swarm subwoofer system setup in my system, and interested in your 300B preamp/power amp and speaker system.

As long as your 300B Preamp able to drive the load, which is around 10K rather than 12K after doing the math (65x12/(65+12))

You have mentioned the output impedance is 400 ohm with the upgraded. Can you explain what is it about?

Many thanks!
