The Pro-Ject MaiA DS3 integrated amplifier is Pro-Ject's new reworked all-in-one compact amplifier solution. It combines both, analogue and digital inputs to suit all different sources.

With 140 watts per channel at 4 ohms you can easily power a decent selection of speakers. The electronics are packed into a beautifully machined full aluminium case which protects it against outside interferences.

Versatile Input and Output Options

The MaiA DS3 offers you the following inputs:

  • 1x Phono (MM or MC)
  • 3x Line (CD player, tuner, etc.)
  • 2x S/PDIF Optical
  • 1x S/PDIF Coax
  • 1x USB
  • 1x Bluetooth 5.0 AptX HD

Use your favourite headphones to privately enjoy your favourite tracks or connect your speakers with 4 mm banana plugs, spades or naked wires to the gold-plated speaker outputs.

The variable RCA outputs also allows you to include a subwoofer or another power amplifier in your setup. Use the fixed output to distribute the audio signal to another device unaffected by the volume control to feed an audio recorder, for example.

With the supplied remote control, you are able to analogue change the volume with the motor driven potentiometer and switch your input.
