Using a Preamp with UR 242....

Im curious as The UR242 has the “D-Pre” preamp stage on channels 1 and 2, when using an external mic preamp is it ok to connect to either channel 1 or 2 at line level or should i use the dedicated channel 3 & 4 line love inputs in the rear ?

thanks for any advice

Always best to use line inputs for external gear with line level outputs.
