NAD PP 2e Phono Preamplifier

NAD PP 2e Phono Preamplifier

The NAD PP 2e Phono Preamplifier is a dedicated, low-noise phono stage designed to bring out the detail, dynamics, and tonal balance your turntable is capable of. Built for both Moving Magnet (MM) and Moving Coil (MC) cartridges, it adds the clean gain and accurate RIAA equalization needed to convert a cartridge’s tiny signal into a stable line-level output that any amplifier, receiver, or powered speakers can use. A carefully tuned, wide-band design helps records sound open and natural, while a gentle infrasonic (rumble) filter supports smoother playback by reducing unwanted low-frequency noise. With an external high-voltage supply, gold-plated input sockets, and smart Auto Power Down, the PP 2e is a simple, high-impact upgrade for systems with basic or no built-in phono input.

What It's Good At:

• Delivering clean, low-noise gain that makes vocals and instruments sound clearer and more present
• Supporting both MM and MC cartridges, making it easy to match a wide range of turntables and upgrades
• Preserving accurate tone and balance with precision RIAA equalization
• Reducing woofer “pumping” and turntable rumble via a gentle infrasonic filter
• Integrating effortlessly with most systems using a straightforward line-level output
• Staying quiet and consistent thanks to an external high-voltage power supply and quality signal-path parts

NAD PP 2e Q&A:

What does the NAD PP 2e do in a turntable system?

It boosts your turntable cartridge’s very low signal and applies RIAA equalization so it becomes a standard line-level signal for an amplifier, receiver, or powered speakers.

Will the PP 2e work with my cartridge—MM or MC?

Yes. The PP 2e supports both Moving Magnet (MM) and Moving Coil (MC) cartridges, making it compatible with a wide range of turntables.

When do I need a phono preamp like the PP 2e?

You need one if your amplifier/receiver doesn’t have a dedicated “PHONO” input, or if you want a cleaner, more detailed phono stage than what’s built into your current gear.

What is RIAA equalization and why does it matter?

Records are cut using an equalization curve; a phono preamp must reverse that curve during playback. Accurate RIAA equalization helps music sound balanced, natural, and consistent from record to record.

What is the infrasonic (rumble) filter used for?

It helps reduce ultra-low-frequency noise from turntable/record vibration that can cause woofer pumping and muddy bass, supporting smoother and more stable playback.

How do I connect the PP 2e to my system?

Connect your turntable to the PP 2e inputs, then run the PP 2e’s line-level output to any standard analog input on your amp/receiver (not a phono input).

Does the external power supply improve performance?

The external high-voltage supply is designed to support stable, quiet operation and help keep noise out of the sensitive phono amplification stage.

Does the PP 2e turn off automatically?

Yes. Auto Power Down places the unit into standby when it’s not in use to reduce energy consumption.
