Product Description
The Cambridge Audio Duo phono preamplifier is a versatile preamp for vinyl players equipped with both MM and MC cartridges.
This model is equipped with a modern specialized switched-mode power supply that provides good shielding and minimizes interference in the signal path. High-quality components with surface mount technology are used in the circuits to increase mounting density and reduce noise, which is important for low-level signals taken from the cartridge. The well-thought-out circuit topology ensures high-quality sound.
The phono preamp features a built-in infrasonic filter to eliminate low-frequency hum that occurs when playing warped or damaged records, preventing speaker overload. The Cambridge Audio Duo model includes a balance control knob on the rear panel, a unique feature for phono preamps. The balance control helps to adjust volume differences between channels caused by various factors, including worn vinyl records.
It also includes a quality headphone amplifier with a 6.3mm output and volume control integrated into the front panel, allowing you to listen to vinyl without connecting to external speakers. The rear of the Cambridge Audio Duo has two RCA inputs for moving magnet (MM) and moving coil (MC) cartridges. A selector button on the front panel allows you to choose the desired input. The linear RCA output is used to connect to amplifiers or active speakers.
The phono preamp has an Auto Power Down function that switches it to standby mode with low power consumption (less than 0.5W). The model features a small all-metal chassis with good anti-resonant properties and a classic design. According to the manufacturer, the Cambridge Audio Duo delivers exceptionally clean analog sound with a warm tone, detailed sound, and precise soundstage.
