Antipodes CORE - Powering On and Off

2 | Antipodes Audio Music Server
TURNING ON & OFF
To power on an Antipodes music server, rst make the
rear panel connections and ensure the power supply
is on. Then click the front panel power button briey,
and wait 2 minutes for the Antipodes to power up fully
before proceeding.
To power o󰀨 an Antipodes music server, click the front
panel power button briey, and wait a few seconds till
the front power light extinguishes. Note that a minor
incompatibility in the design of your DAC’s USB input
may hold a service open on the Antipodes and prevent
shutdown, and the power light will remain on. If this
happens, power o󰀨 by clicking the front panel switch,
wait 20 seconds and then complete the shutdown by
holding the front panel button in until the power light
goes o󰀨.
Only after the power light has gone o󰀨 is it safe to
remove power from the rear of the Antipodes. Failure
to shutdown correctly may require the Antipodes to be
serviced.
StandBy Mode
To maximise sound quality all critical power supply
capacitors remain powered when power is applied to
the rear of the Antipodes, even when the Antipodes is
o󰀨 at the front panel. This is called standby mode.
If you wish to shutdown your Antipodes for extended
periods we recommend you leave the Antipodes
in standby mode, that is, powered at the rear of the
Antipodes. If power is removed for more than a few
minutes, the Antipodes may take up to three days of
being powered to return to its optimum sound quality.
Leaving the Antipodes in standby mode avoids this
warm-up period.
There is a downside to putting your Antipodes into
standby mode with some DACs, due to the way
di󰀨erent DACs are designed. Your DAC may power
down its USB input when you put the Antipodes into
standby and may fail to power the USB input back up
again when the Antipodes is restarted. The problem is
caused by poor design of the DAC’s USB input.
The simplest solution is to restart your DAC after
restarting your Antipodes. Restarting your DAC may
mean turning it o󰀨 at the back panel and back on
again. And DACs with external power supplies may
need the power to be turned o󰀨 and on again at the
external power supply, or at the wall if it does not have
a power switch.
Burn In Period
Your Antipodes music server will only reach peak
performance after about two full weeks of use. During
the rst 100 hours of use the sound can be relatively
poor. At around 250 hours the sound will be good.
Small improvements will be heard after that, perhaps
for a month or more.
The reason for this is that the high quality capacitors
used take a long time to form and therefore for the
power supplies to fully stabilise. Digital circuits need
very nearly perfect power supplies before they can
perform as designed.
