Product Description

Boulder – 1161 stereo power amplifier

At long 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.

The 1161 was thus 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 1161 has the same operational feature set as its larger brother, the 1160, 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:

200W peak power per channel into 8 ohms, 350W peak power into 4 ohms, 450W 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

Complete smart-home and integration compatibility with 12V trigger, IP control, and networked HTML page

Superior signal handling and resolution achieved using Boulder’s own 985 gain stage, just as in the larger 1160 Stereo Amplifier

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

Smaller carton packaging means easier transportation, unpacking, and installation
