Owners Manual

5. ON/OFF and Analogue Volume Control
The analogue volume control in iDSD Diablo is superior to any
digital volume control.
Warning: Due to the high power of iDSD Diablo, always start off at a low volume
level so that there is no risk of damage to your headphones or your hearing. iFi
audio is not responsible for any hearing or equipment damage from misuse.
Power ON. Power OFF.
Tip: For Apple iOS and Android devices, please use battery power, otherwise you
may receive error messages from your device.
Tip: For connection to Apple devices, an Apple Lightning to a USB Camera Adapter
is required. For connection to Android devices, a USB On-The-Go (OTG) cable and
appropriate OS support are required.

Connection for 6.3 single ended headphones . Please use 3.5 to
6.3 mm adaptor for 3.5 single ended headphones.
2. Balanced 4.4mm analogue output
Connect balanced 4.4mm headphones.
Tip: As iDSD Diablo is balanced, we recommend the 4.4mm output.
3. Power Mode
There are 3 different types of power output levels to drive
different headphones from the ultra-sensitive in-ear monitors
to the most demanding over-ear headphones .
Approximate listening time (in Battery mode with typical headphones):
Eco up to a maximum of 12 hours (10)
Normal up to a maximum of 9 hours (8)
Turbo up to a maximum 6 hours (4)
4. Audio Format LED (kHz)
The LED colour scheme indicates the audio format and sampling
frequency received by the iDSD Diablo from the music source.
LED Mode
Yellow PCM 48/44.1kHz
White PCM 768/705.6/384/352.8/192/176.4/
96/88.2kHz

6. S/PDIF 3.5mm Coaxial/Optical input
When USB is not used, connect to a Coaxial/Optical cable (through
a Toslink Mini-Plug).
Tip: a Toslink Mini-Plug to Toslink adaptor is included for connecting a Toslink
optical cable.
Tip: The SPDIF standard supports PCM only up to 192kHz.
7. Balanced 4.4mm fixed analogue output
This is an analogue output via 4.4mm > XLR or other balanced
interconnects. You could use this for an active speaker or an
amplifier.
Warning: Do not insert 4.4mm headphones to this source as the full volume is
likely to damage your headphones or your hearing.
8. USB-C (5V) battery charge input
For charging only. Due the very high-power nature of iDSD
Diablo, it will take ~12 hours and ~6 hours for a standard and
high-powered (the enclosed super-silent iPower 5V ) charger
respectively to fully recharge the iDSD Diablo.
9. LED for Battery Status
LED Status
White* > 75%
Green* > 25%
Red* > 10%
Red (flashing) ≤ 10%
*Battery LED will flash when it is charging.
10. USB3.0 'Type A' input port
For data transfer only. Connect your phone to the iDSD Diablo
with a Lightning to a USB Camera Adapter (Apple) or USB On-
The-Go (OTG) cable (Android). When using other audio sources,
please connect with a USB cable.
Tip: It is preferable to use a USB 3.0 over using a USB 2.0 port on the PC.
Tip: The iDSD Diablo comes with a pre-installed firmware optimised for MQA. This
version also handles up to PCM384/DSD256.
Tip: For firmware optimised to run PCM768/DSD5 12(non-MQA) please install
corres ponding firmware.
