ifi Audio iDSD Diablo User Guide
1. Single-ended 6.3mm output
Connection for 6.3 single-ended headphones. Please use a 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 of 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
Cyan DSD 128/64
Red DSD 512/256
Green MQA
Blue MQA Studio
Magenta Original Sample Rate
MQB
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. 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.
For more information, please refer to www.ifi-audio.com.
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 into 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 to 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 OnThe-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 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 corresponding firmware.
Tip: For all the latest firmware updates please refer to our website here: www.ifiaudio.com/downloads/
