How does the DI output on the PZ-Pre compare to the J48?
The audio circuits in the PZ-Pre and J48 are both active and employ a very similar approach to the way each buffers the signal. Where they differ is that the J48 is limited by the low current of phantom power while the PZ-Pre has a dedicated power supply with more headroom. With less current in the J48, we have to be very careful on what we ask it to do, while the PZ-Pre can be adorned with extras such as an EQ. For instance, when you increase the bass, you are actually increasing the output level at a particular frequency. This places more demand on the power supply which is not a problem on the PZ-Pre. If you are looking for a pure signal, the J48 would be ideal. If you are looking to modify the signal with EQ to tailor your sound, then the PZ-Pre would be the choice.
