  5. ON/OFF and Analogue Volume ControlTechnologies 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.For more information, please refer to www.ifi-audio.com.
  6. S/PDIF 3.5mm Coaxial/Optical inputWhen 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 analog outputThis 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.
  8. USB-C (5V) battery charge inputFor charging only. Due to the very high-power nature of iDSDDiablo, 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
