Yes, you can. The HD4 speakers use a switching power supply so it will automatically convert to the different voltage. The power cable is also detachable which makes it convenient to replace the AC plug with a different type if you don’t want to use an adapter plug.
Sure, for HD4 you will need an inverter that can supply about 50-60 watts.
While the HD4 has a fantastic 24-bit DAC, you can always run your own external DAC to the speakers by connecting to the analog inputs.
Some turntables will need a preamp before being connected and others may have one built-in. Check the turntable manufacturer’s website or user manual.
Yes! All Audioengine powered speakers have multiple audio inputs. Both analog inputs (3.5mm and RCA) are active, so you can connect multiple audio sources at the same time. The digital inputs are slightly different, though. Both the Bluetooth and USB inputs share an internal DAC. In this case, the Bluetooth input will take precedence […]
You should be able to use multiple sources with the HD4s just fine. The analog inputs on the HD4 are always active. They will play at the same time as the Bluetooth or USB input. Bluetooth and USB share the DAC though, so you can only listen to one at a time, and Bluetooth takes […]
Technically, yes. But thankfully, it won’t really be noticeable! Bluetooth only has a delay of about 30ms (milliseconds). So for example, you can watch videos from apps like YouTube and stream the audio through your HD4 without any noticeable lag.
You would connect the variable output of the HD4 into the input of your sub using RCA cables.

Bluetooth LED is on and solid: The HD4 Wireless has power and currently connected to a Bluetooth-enabled device. LED indicator illuminates orange instead of white: This is normal! It means that […]
If the left speaker is in an easy to reach location, you can certainly use the physical knob to set volume. If not though, we generally recommend setting the HD4 at around 50% and adjusting from source.
