McIntosh C55 and C2800 Preamplifier

The C55 Preamplifier takes the baton from its predecessor, the award-wining C53, and adds new features and improved sound quality.

With a highly versatile 9 analog and 7 digital inputs, the C55 becomes the nerve center of your audio system. Analog inputs include 3 balanced and 4 unbalanced connections, along with 2 phono inputs each configurable for either Moving Coil or Moving Magnet phono cartridges to connect your turntables. Both phono inputs feature adjustable Gain in 6dB steps from 40dB to 64dB as well as RIAA equalization.
