Pro-Ject Amp Box DS2
Compact stereo power amplifier from Pro-Ject, in the Box format, designed to complement a source with variable output level.
Description
The Amp Box DS2 is a stereo power amplifier in the compact format characteristic of Pro-Ject's Box range. It is intended to be paired with a source fitted with variable-level outputs, whether a preamplifier, a home cinema amplifier or a network player, rather than to operate on its own.
Its frequency response extends from 10 Hz to 50 kHz, with channel separation greater than 40 dB at 20 kHz and a signal-to-noise ratio of 90 dB, values that point to precise, low-noise stereo reproduction. The gain of 31 dB and the input sensitivity of 1 V on RCA allow for direct matching with a variable-level source, while the input impedance of 47 kohms limits the load placed on that source. Harmonic distortion remains below 0.1% at 90 W, ensuring a signal that stays largely unaltered even under sustained power.
- Stereo line input on RCA
- Gold-plated screw speaker terminals, 4 mm diameter, compatible with banana plugs
- Trigger input/output for power-on linked to the source
This compact format and integration-oriented connectivity are aimed at anyone wishing to build a modular, discreet Hi-Fi system, complementing other units from the same Box range, rather than an installation requiring a conventional integrated amplifier.

What to check before buying used
On this type of external power amplifier, the gold-plated screw terminals warrant a visual check to ensure they grip banana plugs correctly without play. Also check that the trigger input/output works properly, and confirm the presence and condition of the dedicated external power supply, which is essential for the unit to operate.
