I did measure an Allan and Heath desk and some digi-something and they behaved quite differently. The digi provided the voltage immediately after turning it on and quite exactly what you'd expect while the a&h took a few minutes to reach the 48V and it climbed up further. Notice that this was measured without any load, simply with a voltmeter, so the reality might look different. However, I also doubt that 2V off mean a lot to mics. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
