Powering On and Off
The Crimson has no power on/off switch for two good reasons: first of all, cutting the power
off before the external PSU does not truly stop the latter‘s power consumption and, secondly,
the chances of an accidental powering off that could ruin a recording are reduced to zero.
We recommend to connect the Crimson and all other audio devices in the same network to a
high-quality and appropriately rated multi-outlet power strip from where you can cut-off and
restore the power supply. In any case, the connection of the audio network to a central power
outlet is the general recommendation, in order to avoid ground loops and other similar noises
that could arise due to connection points having different potentials.
