Boulder 1163 Stereo Power Amplifier

150W peak power per channel into 8 ohms, 200W peak power into 4 ohms, 400W peak power into 2 ohms

Space saving design is the same footprint (width and depth) as the 1110 Preamplifier and lower power output allows the use of a standard power cord

Smaller carton packaging means easier transportation, unpacking, and installation

Truly balanced input connections and output stage as with other 1100 Series products

Newly developed protection circuitry safely and immediately shuts down the output section in case of shorted speaker cables or faults in the system and allows for greater peak power output

Superior signal handling and resolution achieved using Boulder's own 985 gain stage, just as in the larger 1162 Stereo Amplifier

Revised and redesigned automatic biasing circuit accurately stabilizes bias to eliminate the need for manual calibration

Output stage uses 40 output transistors and 12 supply capacitors to ensure stable, high-power output into any load while maintaining detail and clarity.

Software updates to the internal control and housekeeping systems available as needed with automated online downloads or manual USB port installation
