Description

The 2150 Mono Power Amplifier is the beneficiary of 30 years of amplifier design. It replaces the renowned 2050 Mono Power Amplifier, a benchmark product that stayed in continuous production for almost 18 years.

Having the perfect template to build on, we analyzed, improved, and evolved the 2150 into something much greater than its predecessor. It outperforms it in every way and as a result earned Stereophile magazine’s Amplification Product of the Year award. After all, we don’t aspire to benchmarks. We outdo them.

 

  • Boulder's most powerful continuously manufactured amplifier: 1000W into any load

  • Computer designed surface-mount circuit boards secured in custom-machined frames, each damped to eliminate mechanical distortion

  • Dual toroidal transformers, potted and installed in a welded steel enclosure: transformer hum is not permitted

  • Boulder Link for turn-on and turn-off of amplifiers and to send status messages to the display of any Boulder preamplifier

  • 12V trigger connection for remote turn-on by most surround-sound processors and control systems

  • Two 99H2 gain stages (one for + audio and one for - audio), a third-generation descendent of the 990 gain stage used in recording and broadcast studios world-wide

  • Supervisor board monitors and controls all aspects of the amplifier's operating status

  • Dual gain stage design maximizes bandwidth by incorporating the majority of gain in the first stage

  • Designed as a fully-balanced, true monaural amplifier for ideal loudspeaker interface

  • Full Class-A biasing actively managed with an analog circuit that reduces heat and improves efficiency

  • Massive instant power delivery and damping from 80 bipolar output transistors

  • Dual speaker connections via easy to connect, high-current speaker terminals to accommodate bi-wired loudspeakers
