Stereo Box DS3
The Stereo Box DS3 is Pro-Ject's new reworked classical integrated stereo amplifier solution. It offers one phono (MM & MC capable), three line and one Bluetooth® input. With its 150 watts per channel at 4 ohms you can easily power your favourite speakers.
The whole electronics are packed into a beautiful machined full aluminium case which protects it against outer interferences. The Stereo Box DS3 is handmade in Europe and available in an either black or silver finish.
Versatile input & output options
The Stereo Box DS3 offers you the following inputs:
1x Phono (MM or MC)
3x Line (CD player, tuner, etc.)
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.
Designed & handmade in Europe
The new Stereo Box DS3 is carefully designed and handmade in Europe. The goal was to develop a technically flawless device in a housing that is only as big as necessary to safe raw materials. Due to the timeless design & rigid aluminium casework, it is built for eternity.
With high-quality materials and components, but also well-thought-out design, Pro-Ject want to be a pioneer in the industry.
