Hello,

at this time it is difficult to get the QA472 Low Noise Mic Preamp in Germany/Europe.

It is possible to combine an other Mic Preamp with the QA403 (do you have experience with certain devices from other manufacturers).

What should you consider when adjusting the level of a different preamp?

```auto

```

Please don’t be angry about my maybe stupid questions….

Thank you for all answers

Hallo Diskus

It depends what you want to measure and what the budget is. I’m personally using a QA472 but I know several people who use the img Stage Line / Monacor MPA-102 for measuring e.g. loudspeakers. This alternative preamp offers gain setting in 5dB steps, is available from Monacor or Thomann and I don’t see any reason why it will not make a good mic front end for the QA403.

Regards from Switzerland

Hi @Diskus, you can always order the QA472 directly from US. But @AVO is correct, the amp demands for a mic front end for measuring speakers isn’t that rigorous.
