PeeCeeBee Preamplifier GB

A basic question Shaan,
With an output impedance as low as 32 ohms, can i use the preamp to drive two poweramps.
Powermap input impedance typically shall be 22 Kohms.
or do i need a unity buffer / isolation between preamp and the two poweramps.
if any other precaution required please recommend
 
Hi Hemant.

The preamp is fine with any load impedance from 32ohm upto infinity. So yes, you can drive 22kohm inputs with the preamp without any problem. No need for unity buffer, isolation etc. The very low output impedance actually helps the preamp isolate your signal source from the amplifier as good as a buffer. Just use good shielded cables and that's all.
