MoFi MasterPhono Phono Preamplifier

The dual-chassis construction physically separates the power supply from the sensitive audio circuits. This isolation significantly reduces electromagnetic interference, resulting in a lower noise floor and a cleaner, more detailed signal.

Yes, the MasterPhono is highly versatile and supports both MM and MC cartridges. It features selectable gain settings from 40dB to 70dB and adjustable loading, allowing you to dial in the perfect match for almost any cartridge on the market.

While standard voltage-based inputs are common, the current-based input option provides an alternative way to handle low-output Moving Coil cartridges. It can offer a different sonic character and improved impedance matching for specific MC designs, giving you more flexibility to fine-tune your system's sound.

No, the MasterPhono is a dedicated, pure analog phono preamplifier. It does not include a headphone amplifier or an analog-to-digital converter, as its primary focus is maximizing the performance of your analog signal path.

The included remote control allows you to adjust key settings like input selection, gain levels, and filter engagement from your listening position. This is particularly useful for comparing different loading settings or gain stages without having to get up and manually adjust the unit.

The subsonic filter is designed to remove ultra-low frequency rumble, often caused by warped records or turntable motor noise. Engaging it helps protect your speakers from excessive woofer excursion and cleans up the overall sound by preventing these unwanted frequencies from muddying the audio.
