Boulder 3050 Mono Power Amplifier (pair)

Boulder's biggest, most powerful, and highest performing amplifier, each built to order for its new owner

Completely designed, manufactured, and hand-assembled at our facility in Louisville, Colorado

1,500 watt power output into any load means absolute clarity and control of loudspeakers

Aluminum base, cut to match the angles and footprint of both the left and right amplifiers

Intelligent microprocessor control so amplifiers can automatically set proper turn-on sequence via Boulder Link and transmit any necessary information to a Boulder preamp's display

Every 3050 contains two of Boulder's highest performing gain stages, the 99H, available only in 3000 Series products

Full Class-A biasing to maximum output, managed with an analog circuit that reduces bias current whenever possible to increase efficiency and reduce heat

120 output transistors for unequaled damping and power delivery

Four transformers per amplifier, each DC filtered, sealed in machined housings, and potted in a proprietary epoxy for silent operation

Circuit boards are installed in aluminum mounting frames precisely machined to fit the board and sandwiched with a layer of damping material

Left and right amplifier chassis are mirror-imaged and feature multiple surface angles to break up any reflected sound

Differentially balanced, instrumentation-style input circuitry for ideal electrical interface with any preamplifier or source component
