1. PowerMatch (High/Low)
PowerMatch setting should be on low for IEMs and on high for on/over
headphones.
LED Status
White High
Off Low
WARNING: Due to the high power of ZEN DAC 3, before changing the PowerMatch setting, always start off at a
low volume level so that there is no risk of damage to your headphones, speakers or your hearing. iFi audio is
not responsible for any hearing or equipment damage from misuse.
2. XBass+ On/Off
Many headphones lack the correct bass response. XBass+ was uniquely designed as
an analogue circuit designed to 'add back' the lost bass response for the most
accurate playback.
Tip: Open headphones (lack of bass due to structural design) and some highly sensitive earbuds (lack of bass
due to unit size limitations) sound better when XBass+ is on, or can be adjusted to suit personal preference.
