Music Hall pa2.2 Phono, A2D, & Headphone Preamplifier

The Music Hall pa2.2 phono amplifier is the ultimate tool for vinyl enthusiasts. It features an ultra-quiet MM/MC phono amp, high-grade headphone amp, analog-to-digital converter, and high-resolution 2-input pre-amplifier in one sleek package. With fixed or variable line output capability, you can record vinyl or any line level source to your computer with ease.

The pa2.2 also includes an adjustable MC gain stage, USB digital output, and Apple Mac and Windows compatibility. Its high-performance 24bit/96kHz analog-to-digital converter, superior wolfson WM8786 ADC, and tenor TE7022 24bit/96kHz USB receiver deliver unrivaled sound quality.

The phono amp also boasts a phase/invert switch for perfect audio phase, gold-plated RCA inputs and outputs, and silky smooth high-grade Alps “blue velvet” volume control. Its solid alloy construction and vibration damping feet ensure durability and stability. The pa2.2 is truly a Swiss Army knife of phono amps that delivers unparalleled versatility and performance.
