How to know whether the ZEN DAC are actually powered from USB or 5V DC external power supply?
If ocnnected, an external PSU is auto-selected.
However, when I try plug in the 5V DC external power supply... only the External Power indicator at the back lights up (Green). The unit wouldn't turn on... No lights on the front (Volume Knob)... Power Match and True Bass wouldn't light after press... until i plug in to PC/Latop/HP...
That's by design. LEDs on the front are engaged once audio data is sent to the product.
If the ZEN DAC are powered by the 5V DC external power supply, why it drain the battery from phone... After about an hour listening with HFM Sundara (Power Match and True Bass both ON, Volume around 10-11 o'clock), the phone battery drops from 100% to 91%. With the HIP DAC... the phone battery only drops like 1-2%... Seems like ZEN DAC are drawing power from USB via instead of the 5V DC external power supply.... How do i make sure the ZEN DAC only draw power from the 5V DC external power supply instead from the phone....
ZEN DAC auto-senses its power source, and with externally provided 5V it doesn't draw power from USB. But if you feel that the disparity in battery usage of your smartphone is too big, please open up a ticket here: https://support.ifi-audio.com
Perhaps one of our tech staff encountered something alike already.
Hi @iFi audio is there any report of channel imbalance on the volume pot of ZenDac? mine out of the box from 0 - 15% only left channel has sound and the right channel only has sound in 20% vol (08:30 position). Playing from Foobar using 4.4 Bal phone out.
A small channel imbalance early on is normal, but both channels should be equal during normal listening volumes.
