Questions & answers about the

HD4 Home Music System w/Bluetooth aptX-HD

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 peaker. 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.

The HD4 has a built in USB digital-to-analog converter (DAC), but can I also use a different DAC?

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.

If I connect my turntable to the HD4 will it be necessary to purchase a phono preamp or can I simply connect the turntable directly to the HD4 input?

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.

Is it possible to connect multiple sources to the HD4 simultaneously?

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 over the USB connection. This means that the Bluetooth input will mute the USB input's audio playback. Simply
disconnect your Bluetooth device from the HD4 speakers to resume
playback from your USB source device.
