Pro-Ject Audio Systems Amp Box RS2 Instructions Manual page 4

Bridge Mode
The Amp Box RS2 can be configured to work as a mono amplifier (Bridge Mode) which offers a higher output
power.
- Connect your speaker to the marked "Bridge +" and "Bridge –" speaker outputs.
- Connect the input cable to the left channel XLR input on Amp Box RS2
- Activate Bridge mode by pressing the "Bridge" button
Minimal speaker impedance in bridge mode is 8 ohms.
Clipping
The clipping indicator shows that the amplifier starts to clip or overdrive at its output, which can damage
loudspeakers, and degrade the sound.
 Turn down the volume of your preamplifier.
Thermal protection
When the operating temperature gets too high, the amplifier will shut off & the "Thermal protection" indicator
lights up. Over temperature can be caused by high listening levels and wrong placement.
 Let the amplifier cool down. It will return into normal operation mode automatically.
The Amp Box RS2 uses a convection cooling system to regulate the operating temperature. Air enters
through the vents on each side and the bottom of the amplifier chassis and exits through the sides and
top of the chassis.
Make sure that there is enough space around the amplifier to allow the heated air to exit. If the Amp
Box RS2 is mounted in a rack, please do not use the doors as this could cause a heat buildup. Whatever
type of rack you are using, make sure that the heated air can escape freely.
DC protection
The DC protection protects speakers from constant DC voltage. Although it is a rare fault, it can destroy your
speakers if happening.
 The amplifier will return into normal operation mode automatically. If the fault occurs, please contact
your dealer.
