What the X-POWER TT Replaces
Most turntables ship with a small switching adapter — a wall wart — that provides basic DC power. The Musical Fidelity X-POWER TT is a linear power supply designed to take its place. It delivers 15 volts DC at 2 amps, with a transformer that isolates the turntable from mains noise. The upgrade is a five‑minute swap that requires no tools or settings.
How to Install the X-POWER TT
The installation is straightforward because the X-POWER TT uses a standard DC plug and voltage that matches Musical Fidelity's own turntables. Follow these steps to replace the stock adapter.
- Power down the turntable: Switch off the turntable and unplug the original wall wart from the wall socket. This prevents any accidental connection while you work.
- Disconnect the original adapter: Pull the DC plug of the original adapter out of the turntable's DC input socket. Set the old adapter aside.
- Connect the X-POWER TT: Take the DC lead from the X-POWER TT and plug it into the same DC socket on the turntable. The connector fits firmly and is keyed to prevent reverse polarity.
- Plug the X-POWER TT into the wall: Connect the supplied IEC C14 power cord from the X-POWER TT's rear inlet to a wall outlet. The unit runs on 115 volts AC at 50 or 60 Hz.
- Power on and enjoy: Turn on the turntable as usual. The X-POWER TT has a soft‑start circuit that limits inrush current, so the system powers up smoothly. No further configuration is needed.
Key Specifications of the X-POWER TT
- Musical Fidelity X-POWER TT Turntable Power Supply: Output is 15 volts DC at 2 amps, regulated to within half a percent. This ensures consistent voltage to the turntable motor electronics, even under load from a heavy platter.
Musical Fidelity X-POWER TT Turntable Power Supply - Musical Fidelity X-POWER TT Turntable Power Supply: Filtration uses 10,000 microfarads of low‑ESR capacitors for low noise. More capacitance helps smooth out ripple and reduces high‑frequency noise that can affect the phono signal.
- Musical Fidelity X-POWER TT Turntable Power Supply: The chassis is extruded aluminum in the X‑profile with a brushed faceplate. The metal enclosure provides better shielding and heat dissipation than a plastic wall wart, and it sits beside or behind the turntable rather than dangling from the wall.
Compatibility Check Before You Buy
The X-POWER TT was designed for Musical Fidelity's Roundtable S, Roundtable S2, M6xTT and M8xTT turntables. These decks generate their own AC for the motor from a DC‑driven generator, so the X-POWER TT feeds that circuit with cleaner DC. If you own a different turntable, check that it requires 15 volts DC at 2 amps and that the plug polarity matches. Some Pro‑Ject models are compatible, but it is safest to confirm before ordering.
