MM/MC phono preamp

Squeeze every bit of detail out of your vinyl collection with the highest quality Cambridge MM/MC phono preamp, with integrated headphone amplifier.

Vinyl, how it should sound

Whether it's blowing the cobwebs out of your record collection or jumping on the analog bandwagon with the resurrection of vinyl, the moment you place the needle on your favorite album is a magical moment. To preserve the unique warmth of vinyl sound, the Duo preamp has been carefully designed with a power supply that includes the latest in toggle modes and a new layer of surface-mounted circuitry to reduce unwanted noise.

Why choose a dedicated preamp?

Considering how weak the signals emitted by a turntable are, not all HiFi amplifiers allow a direct connection. The phono preamp strengthens that signal to a point where the amplifier can work with it. The challenge in that phase of playback is to avoid noise, which can so easily corrupt the signal.

That's why Cambridge has designed the Duo with exceptional parts that deliver the warm, detailed sound synonymous with vinyl, without all the signal corruption of the MM cartridge turntable. The toggle-mode power supply enhances playback by toggling beyond the audible frequency to noticeably minimize noise while the new circuit layer uses surface-mounted parts for the same purpose.

Vinyl, just for you

Enjoy the warmth of vinyl in private thanks to the Duo's included headphone output. Setting itself apart, Cambridge has included a 6.35mm Jack directly in the preamp, to allow the user to enjoy their records even when they cannot use the speakers.

The integrated headphone output also means you don't have to turn on the amplifier just to power the headphones, making for a more environmentally friendly listening experience.

Attention to detail

If wear and tear has taken its toll on some vinyl in your collection, the subsonic filter will help eliminate the low-frequency hum that these imperfections often cause in vinyl. Together with the balance control to manage potential capsule imbalances (which may cause differences between the left and right channels), it achieves a detailed experience with precise soundstage.

Eco Friendly

The Cambridge Duo phono preamp has an environmentally friendly heart, consuming half a watt media in Standby and automatically turning off if it detects no activity for 20 minutes. Additionally, the unit is compatible with universal voltage, allowing it to be used anywhere in the world.
