Codex Ayre - AC Power

Line-Level Outputs
Plugging standard
(single-ended) headphones into
the front panel will cause the
rear-panel output signals to be
incorrect. See “Controls and
Operation” for details.
The rear of the Codex features both balanced and
single-ended outputs for use with stereo systems
using amplifiers and speakers. Balanced connections
are made via XLR connectors, while single-ended
connections are made via RCA connectors.
When you have a choice, a balanced connection
will offer slightly higher sound quality than a
single-ended connection.
It is not possible to connect the XLR
outputs to conventional single-ended
equipment with RCA input jacks
without damaging the Codex.
Attempts to do so will void the
warranty.
AC Power
The Codex may be plugged directly into an
unswitched wall outlet. Although proprietary RFI
(radio-frequency interference) filtering is built into
the unit, in some situations an AC power-line filter
(such as those offered by Ayre) may provide
additional sonic benefits.
As virtually all computers use switch-mode power
supplies that introduce unwanted RFI on the AC
power line, it may be beneficial to use an AC power
line filter for the computer and its accessories (e.g.,
display monitor), many of which also utilize
switch-mode power supplies.
