Audioengine HD3 Music System

No, the HD3 system is self-powered. It features built-in Class AB amplifiers, so you can connect your audio source directly to the speakers without needing any extra equipment.

Yes, you can connect a turntable to the HD3 speakers using the analog inputs on the back. If your turntable does not have a built-in preamp, you will need to add an external phono preamp between the turntable and the speakers.

The built-in dedicated headphone amplifier is significantly higher quality than the standard output found on most computers or phones. It provides a cleaner, more detailed signal that can drive high-impedance headphones much more effectively.

The bass reduction switch is designed for when you want to add a separate subwoofer to your setup. Engaging it rolls off the low-end frequencies from the main speakers, allowing the subwoofer to handle the bass more efficiently and preventing muddy sound.

The HD3s are designed primarily for near-field listening, such as on a desktop, in a small home office, or in a bedroom. While they produce impressive sound for their size, they are not intended to fill a large living space with high-volume audio.

Yes, the HD3 supports aptX-HD Bluetooth, which allows for high-fidelity wireless streaming. This provides a noticeable improvement in clarity and detail compared to standard Bluetooth connections, provided your source device also supports the aptX-HD codec.
