The Audiolab PPA7 Phono Preamplifier delivers exceptional vinyl extraction, dynamic warmth, and ultra-quiet background levels for modern high-fidelity analog systems. Designed with a fully discrete, ultra-low noise input stage, the Audiolab PPA7 Phono Preamplifier accommodates both Moving Magnet (MM) and high- or low-output Moving Coil (MC) cartridges with pinpoint RIAA equalization accuracy. Featuring comprehensive front and rear panel adjustments for capacitance, resistance, and gain matching, the Audiolab PPA7 Phono Preamplifier ensures optimal cartridge loading. Outfitted with both single-ended RCA and balanced XLR outputs inside a heavy-duty shielded aluminum chassis, the Audiolab PPA7 Phono Preamplifier preserves delicate low-level phono signals from external RF interference.
Key Features & Innovations
Ultra-Low Noise Discrete JFET Input Circuitry — the Audiolab PPA7 Phono Preamplifier utilizes hand-selected JFET transistors to provide maximum gain with minimal noise floor distortion.
Selectable MM / MC Cartridge Loading — fine-tune resistive and capacitive loading parameters to match the exact physical and electrical characteristics of your turntable cartridge.
Precision Equalization Network — high-grade polypropylene film capacitors and close-tolerance metal film resistors deliver exceptionally accurate RIAA equalization curve compliance.
Balanced XLR & Single-Ended RCA Outputs — features balanced outputs for long cable runs to preamplifiers or integrated amps without signal loss or ground hum.
Dedicated Subsonic Low-Cut Filter — built-in switchable subsonic filtering attenuates ultra-low frequency warp rumble without degrading musical bass response.
FAQ — Audiolab PPA7
Does the Audiolab PPA7 support both Moving Magnet and Moving Coil cartridges?
Yes, the Audiolab PPA7 Phono Preamplifier includes dedicated circuitry and switchable gain modes for both Moving Magnet (MM) and low/high-output Moving Coil (MC) cartridges.
Why is adjustable cartridge loading important on a phono preamplifier?
Adjusting capacitance and impedance allows you to optimize frequency response and tonal balance based on your specific cartridge manufacturer specifications, avoiding harsh highs or rolled-off details.
Can I connect the PPA7 directly to an amplifier without a main preamplifier?
The PPA7 is a fixed-line phono stage designed to connect into a standard line-level input (AUX, CD, Tuner) on an integrated amplifier, receiver, or dedicated system preamplifier.
What is the purpose of the subsonic filter button?
The subsonic filter cuts harmless ultra-low frequency feedback caused by warped vinyl records, preventing woofer pumping and reducing amplifier power strain.
