Versatility, Performance, Compactness, Affordability: Four-In-One Music Hall pa2.2 MM/MC Phono Preamplifier Also an Analog-to-Digital Converter, Headphone Amp, and Preamp
Dubbed by Music Hall "the Swiss Army Knife" of MM/MC phono preamplifiers, pa2.2 is actually a four-in-one component that also serves as an analog-to-digital converter, headphone amplifier, and line-level preamplifier. Apart from its versatility, performance, and compact size, the best part about pa2.2 just might be its incredibly low price. No mere pushover, this flexible all-in-one component delivers high-quality sound and provides a laundry list of features. For starters: The extra-quiet MM/MC phono preamplifier with adjustable MC gain combined with a 24-bit/96kHz Wolfson ADC and high-resolution two-input preamp (phono and line level) that allows you to record vinyl LPs or any line-level source directly to your computer. Then, add in a Tenor TE7022 24-bit/96kHz USB receiver, USB digital output, and a phase/invert switch for high-end sonics. Want to archive mono records? Easy. pa2.2 is compatible with mono and stereo LPs, and its Alps "blue velvet" volume control and external-switch-mode power supply further elevate what you'll hear no matter what source or function you select. Top it off with a high-grade headphone amplifier for intimate listening sessions and solid top-to-bottom construction, and pa2.2 is your new best friend for computer audio functions as well as traditional music listening. And of course, it's backed by our Money-Back Guarantee.
