ATOLL PH100 Phono Preamplifier

The PH100 phono preamp is an external module that has a specific power supply consisting of 2 high-end transformers (one per channel) with very low noise as well as 4 voltage regulators. The assembly is shielded by a metal box in order to preserve any interference on the audio stages. Entirely with discrete components, it does not include any link capacitors. The configurations (MM/MC, input impedance) are directly accessible from the rear of the chassis.

OVERVIEW

The ATOLL PH100 is a high-quality phono preamplifier that is designed to deliver exceptional sound quality when playing vinyl records. It features a fully balanced design, high-quality components, and precise engineering, making it a popular choice for audiophiles and music enthusiasts who value accurate, detailed audio reproduction.
