Accuphase AD-2900 Phono Input Board

Accuphase AD-2900 Phono Input Board with 2 Tonearm Inputs

The Accuphase AD-2900 is a beautifully executed phono equaliser board that brings serious analogue performance to any compatible Accuphase preamp. Once installed in a rear-panel slot, it lets you enjoy your records with the same refined polish and quiet authority you’d expect from Accuphase’s standalone components. With separate input circuitry for both MC and MM cartridges, the AD-2900 matches each pickup type with precision, delivering an impressively low noise floor and a smooth, confident presentation that feels effortlessly musical.

Accuphase has engineered the AD-2900 with meticulous attention to detail, starting with equaliser boards made from glass-cloth fluorocarbon resin and fully separated left and right channels. The result is superb channel integrity and RIAA accuracy, thanks in part to its differential-style equaliser topology. Whether you’re running a classic MM or a more demanding MC cartridge, the dedicated circuitry and ultra-low-noise bipolar transistors ensure the signal remains pure, stable and remarkably quiet.

Flexibility is another strong point. The AD-2900 provides two sets of inputs - AD1 and AD2 - allowing you to connect two tonearms or two turntables and switch between them straight from your preamplifier’s front panel. Each input can store its own memory settings, making it easy to optimise gain and impedance without fuss. With MC gain options of 64 or 70 dB and selectable impedances from 10 to 300 ohms, plus MM gain settings of 34 or 40 dB with the standard 47 kΩ load, fine-tuning your analogue chain becomes a pleasure rather than a chore.

All of this is housed in a robust aluminium enclosure that shields the delicate circuitry from external noise, maintaining the AD-2900’s refined sonic character. Designed to integrate seamlessly with a wide range of Accuphase preamplifiers, it’s the kind of upgrade that immediately elevates playback while keeping operation intuitive and elegant - very much in the Accuphase spirit.

Why Choose The Accuphase AD-2900

The Accuphase AD-2900 is one of those upgrades that quietly transforms your analogue setup, pairing an easy, almost luxurious listening experience with some seriously thoughtful engineering. Once slotted into your preamp, it treats your records with the same calm refinement you’d expect from Accuphase’s standalone gear, thanks to dedicated MC and MM input stages that keep noise impressively low and music flowing effortlessly. Its beautifully made boards, differential equaliser topology and fully separated channels all work behind the scenes to maintain superb accuracy and tonal purity, while two switchable inputs with memory settings make juggling multiple tonearms or turntables wonderfully simple. Add in the robust aluminium enclosure and generous gain and impedance options, and the AD-2900 comes across as a remarkably complete phono solution - uncomplicated to use, elegantly executed and unmistakably Accuphase.
