Pro-Ject Phono Box Phono Preamplifier

The classic phono stage that just works

The Pro-Ject Phono Box is the entry point to Pro-Ject's phono stages. It accepts both moving magnet and moving coil cartridges through a rear-panel switch, then feeds a clean line output straight to your amplifier. A small footprint means it sits neatly beside the record player. Sold as a single unit in black.

Why You'll Love It

• Ready for most turntables. A rear-panel switch moves between moving magnet at 40 dB and moving coil at 60 dB, so it suits a wide range of cartridges.
• Runs quiet and green. Low noise ICs keep the signal clean, while the DC power supply draws under 1 watt on standby.
• Easy to place. The compact case tucks in next to the record player and connects through gold-plated RCA sockets.

Under the Hood

• MM and MC loading. 47 kΩ for moving magnet and 100 Ω for moving coil, both at 120 pF.
• Ultra-low output impedance. The output stage drives your amplifier cleanly with up to 9.5 V maximum output at 1 kHz.
• Accurate RIAA. The equalisation curve holds to within 0.5 dB across 20 Hz to 20 kHz.

CHT Insider Verdict

The Phono Box is a straightforward, well made way to get a turntable talking to an amplifier that has no phono input. It has been a long standing best buy for good reason, covering both cartridge types in a box you can hide behind the system.

Pro Tip: Switch to MC only if your cartridge is a moving coil design. Most starter cartridges are moving magnet, so leave it on MM and 40 dB gain.
