Boulder 1161 Stereo Power Amplifier
At last, there is a solution for listeners with smaller living spaces or more efficient systems. Those who want a genuinely high-performance amplifier in a more manageable package. There are systems and locations where larger amps don’t fit, or more powerful options are unnecessary. The Power Amplifier is a compact, less powerful alternative that gives up performance. The dynamics, the control, the delicacy, the resolution–everything is still there. There are no sonic drawbacks. 1161 has the same operational feature set as its larger brother, 1160, and yet it’s packaged in a chassis the same width and depth as the 1110 Preamplifier. So you see, it is possible to have everything, even with less.
Boulder 1161 Stereo Power Amplifier Features
-
200W peak power per channel into 8 ohms, 350W peak power into 4 ohms, 450W peak power into 2 ohms
-
Space-saving design is the same footprint (width and depth) as the 1110 Preamplifier. Lower power output allows the use of a standard power cord.
-
Smaller carton packaging means more accessible 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.
-
Boulder’s own 985 gain stage achieved superior signal handling and resolution, just as in the larger 1160 Stereo Amplifier.
-
Revised and redesigned automatic biasing circuit accurately stabilizes bias to eliminate manual calibration.
-
Complete smart-home and integration compatibility with 12V trigger, IP control, and networked HTML page
-
With automated online downloads or manual USB port installation, software updates to the internal control and housekeeping systems are available as needed.
