Product Description

Boulder – 2160 stereo power amplifier

Great products don’t just appear, they evolve, built on the technology and the style of what came before them.

The 2160 is the stereo amplifier from Boulder that replaced the venerable 2060,

a brilliant amplifier that earned awards world-wide. The electronics are updated and the look and feel

have evolved with a new satin metal finish. Yet the 2160 remains uniquely Boulder.

That is, it looks, feels, and sounds better than anything you’ve ever heard.

Features:

Bias operation is Class-A to full rated output power and managed with an analog circuit that minimizes heat and power consumption.

Boulder’s most powerful, continually produced stereo amplifier: 600W per channel.

Surface-mount circuit board design minimizes connection resistance and inductance.

Non-resonant chassis cut from solid plates of aluminum on Boulder’s own CNC machining centers.

Four fully-discrete 99H2 gain stages, potted and housed in machined shells for thermal stability and shielding.

Two massive transformers are filtered, potted, and enclosed in a welded steel case.

Power cycling, turn on sequencing, and status messages sent to Boulder preamplifier displays via the Boulder Link communication system.

12V trigger connection for remote turn-on and use with most surround sound processors and external control systems.

Supervising microprocessor circuitry controls and monitors protection systems,

and the turn-on and turn-off of any linked amplifiers.

Dual stage design incorporates the majority of gain in the first stage to maximize bandwidth and minimize distortion.

Two pairs of speaker connections per channel to accommodate bi-wired loudspeakers.

Fully balanced design from inputs to outputs reduces distortion and noise.
