turned off when its use is not required.
An adapter is available from Ayre should you

AC Power
The CX-7e MP may be plugged directly into an
unswitched wall outlet. Although proprietary RFI
(radio-frequency interference) filtering is built into
the CD player, in some situations an AC power-line
filter (such as those offered by Ayre) may provide
additional sonic benefits.
