ON/OFF and Analogue Volume Control
Technologies The analogue volume control in iDSD Diablo is superior to any digital volume control.
• Octa-DSD512/PCM768 and 2X DXD.
• Native DSD/PCM Burr-Brown® chipset.
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.
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.

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. -
Balanced 4.4mm fixed analog output
This is an analog 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. -
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. -
LED for Battery Status
| LED | Status |
|---|---|
| White* | > 75% |
| Green* | > 25% |
| Red* | > 10% |
| Red (flashing) | ≤ 10% |
*Battery LED will flash when it is charging.
- 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 a pre-installed firmware v5.30 optimized for
MQA. This version also handles up to PCM384/DSD256.
Tip: For firmware optimized to run PCM768/DSD5 12(non-MQA) please install firmware v5.20.
