Power control
Mains power
In regular use mains power can be left connected
permanently.
When unattended for a long period (holidays etc) mains
power should be disconnected.
Standby/Status indication
When mains power is connected, the Standby/Status
indicator will initially flash to show the firmware version
(refer to the ‘Firmware’ section of this user guide for more
information), then light red as standby is set.
When a connected product switches on the Standby/Status
indicator will change to the colour of the connected Cyrus
product. This confirms that power is now being supplied
from the PSU-XR.
NOTE: If the PSU-XR remains in Standby then a firmware
update may be required for the connected Cyrus product.
Refer to the ‘Support’ pages of the Cyrus website www.
cyrusaudio.com to determine whether an update is
required.
Auto Standby
There is no energy saving auto-standby setting for the
PSU-XR as it will always set to the same power state as the
Cyrus product it is connected to.
If auto-standby is required it can be enabled at the
connected product.
