highest-quality discrete components and operate purely
in the analogue domain. Hence all the clarity and

Tip: Under Battery Power mode, the micro iDSD will
continue to use battery power even if the USB cable is
connected afterwards.
Tip: For Apple iPhone/ iPad/iPod Touch, Android devices,
please use Battery Power, otherwise you may receive error
messages from your device.
Tip: For connection to Apple devices, the Apple USB

9. Power Mode
There are 3 dierent types of power
output levels to drive dierent head
phones from the most sensitive In-Ear-Monitors(IEMs)
through to the most demanding over-the-ear
headph
ones.
Ap
proximate listening time (in Battery mode with typical
headphones)
Eco ..... = for high-sensitivity IEMs
(Default, ~12 hours).
Normal
= for medium-sensitivity headphones
(~19 hours).
Turbo. = for the most-demanding headphones
(~6 hours).
T
ip: See section 12. For how Power mode is used in conjunction with
Direct/Preamplier mode.
WA
RNING: when rst starting out, do not set the
volume control higher than 9 o' clock and only in
“Eco” mode as the headphone amplier of the iDSD
is exceptionally powerful. iFi is not responsible for
any headphone/hearing damage arising from
incorrect use.
10. Pol
arity
Adjustable signal polarity of music
playback. For a digital signal source only (ie. not for an
analogue signal via the 3.5mm input.)

Tip: For PCM we recommend “Bit-Perfect” for listening and
“Standard” for measurements. For DSD, select
Extreme/Extended/Standard to nd the one that sounds
best for listening and “Standard Range” for
measurements.

With the iEMatch, even the most
sensitive In-Ear-Monitors (IEMs) can
be matched to the iDSD.

High Sensitivity: For High Sensitivity IEMs.
Ultra Sensitivity: For Ultra Sensitivity IEMs.
14. SmartPower®
The USB type “A” port located to the
side is able to recharge a Smart device.
SmartPower® will automatically detect an
iPhone/Android or similar and commence charging.
However, the micro iDSD must be switched OFF as it
cannot charge
Tip:
Any USB connected device can be recharged but with
larger devices such as tablets, the SmartPower battery
will charge, but will be rapidly drained. Hence, it is not
recommended for such applications
Tip: MAC OSX (10.6 or later) has built-in native support for the iDSD.
MS Windows
(XP or later), please download and install the driver
software BEFORE connecting the iDSD to the comp
(www.i-audio.com).
Tip: For the
best sound quality, always set the volume control on
the computer and the playback software to 100%.
