Product Description
Boulder – 1162 stereo power amplifier
The art of technological progress, beautifully expressed in the art of visual design, in an amplifier of truly remarkable ability.
Let us present to you the Boulder 1162 Stereo Power Amplifier, awe-inspiring and modern, yet staying true to Boulder’s long-standing guiding principle: maximize performance.
Every circuit has been refined and every mechanical detail has been optimized.
Everything about the 1162 is the culmination of the 40 years of engineering prowess.
As a result, it is exactly what you would expect: brilliant.
Features:
Class-A Smart Current biasing circuit
300 watts of output power can drive any reasonable loudspeaker to realistic levels
32 Amp IEC pre-terminated power cord supplied in order to safely transfer power to the 1162 and provide absolute maximum performance
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
Updated Ethernet-enabled supervisor circuitry monitors amp, protection systems, and IP and HTML control; improving reliability and longevity
Dual power transformers are DC filtered and enclosed a welded steel case for perfectly silent operation
Boulder Net control access connects to networked systems & integrated homes and links the 1162 with other Boulder products
Four pairs of high-current speaker connections to easily accommodate for bi-wired loudspeakers
Machined front panel depicts the topography of Flagstaff Mountain near Boulder, Colorado
