Frequently Asked Questions
How easy is it to set up HD4?
HD4 is an all-in-one system with no extra components needed except your phone or computer. Simply place the speakers where you want them and connect the power supply. Hook up the included speaker wire from the powered left speaker to the right passive speaker. Then connect your music with the supplied cables - or go wireless - and that's it.
Does HD4 come with speaker grills?
The HD4 speakers do include detachable magnetic grills. The grills have thin rubber pads to prevent marks or damage to the finish or the cabinet, so your HD4s will keep looking great even if you like to remove / replace them frequently!
Can I use the HD4 with tablets or smartphones like Samsung Galaxy or Microsoft Surface?
Absolutely! The HD4 offers wired or wireless connections to any phone or tablet using the aux audio input or Bluetooth aptX-HD. For wired connections to newer devices without a headphone jack, you'll need the correct USB-A adapter cable to connect from your tablet to the USB input on the HD4. These are generally available from the manufacturer of your tablet/smartphone, local electronic stores, or even online retailers.
Can I take my Audioengine HD4 speakers to another country with a different voltage?
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.
Can I use an inverter with my HD4 speakers?
Sure, for HD4 you will need an inverter that can supply about 50-60 watts.
