3010 — Preamplifier

• Matched, dual-phase 993SD gain stage improves thermal tracking and optimizes ground

• Variable Blend control allows recordings with hard-panned images or mono LPs played with stereo cartridges to create a stable center image

• Ethernet connection downloads future software updates and connects to IP-based home control systems

• Three balanced outputs can be operated independently for multiple zones or together for bi- or tri-amplification

• Boulder’s own fully-balanced volume control significantly reduces distortion and step noise

• Programmable Soft mode temporarily reduces output to levels suitable for conversation

3050 — Mono Power Amplifier

• 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

• Black granite and stainless steel 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

3060 — Stereo Power Amplifier

• Production of the 3060 is extremely limited and every unit is built to order

• All assemblies are completely designed, manufactured and hand-assembled at our facility in Louisville, Colorado

• 900W per channel power output into any loudspeaker load

• Each amplifier is shipped with a machined aluminum and polished stainless steel base that is cut to match the footprint and casework angles of the amplifier

• Contains four (two per channel) of Boulder’s highest performing gain stage, the 99H

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

• 60 bipolar output transistors per channel mean unmatched control of any loudspeaker system

• 48 massive filter capacitors are part of an ultra-responsive, low-impedance power supply

• Five power transformers, housed in machined cases and potted to absolutely eliminate any noise, vibration or hum
