A pre-amplifier designed to add or take nothing from the audio input. Driven from an oversized transformer and sophisticated power supply, each amplification stage uses an independent power supply to ensure as little crosstalk and distortion as possible. A ladder resistor volume control ensures the cleanest sound path, selected for neutral impact on the music signal. Inputs include 5 x single ended RCA and 1 x balanced XLR, single ended and balanced outputs provided for connection to a power amplifier stage.
