Amp Box RS
The Pro-Ject Audio Systems Amp Box RS is a high-end stereo power amplifier with a fully balanced double-mono topology, highly efficient pulse-width-modulation modules, and a tube buffer input stage using two ECC88 (6922) tubes. It delivers 2 × 110 W at 8 ohms or 2 × 180 W at 4 ohms, supports 2-ohm loads, and provides RCA and XLR inputs, a 22 kOhm input impedance, and a damping factor of 400 at 8 ohms and 200 at 4 ohms. Its metal casing is available in silver or black, with 4 mm banana, spade, or bare-wire speaker terminals and an external 48 V/2.5 A DC power supply.
