Boulder – 1163

Product Description

Boulder – 1163 stereo power amplifier

At last, there is a solution for listeners with smaller living spaces or more efficient systems.

Those who want a truly high-performance amplifier in a more manageable package.

There are systems and locations where larger amps simply don’t fit or more powerful options are unnecessary and the 1163 Stereo Power Amplifier was developed as a compact, less powerful alternative that gives up nothing in terms of performance.

The dynamics, the control, the delicacy, the resolution–everything is still there.

There are no sonic drawbacks.

The 1163 has the same operational feature set as its larger brother, the 1162, and yet it’s packaged in a chassis the that’s same width and depth as the 1110 preamplifier.

So you see, it is possible to have everything, even with less.

 

Features:

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

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

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

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

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

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

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

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