Boulder 2108 Phono Preamplifier

Three pairs of balanced inputs allow connection to three different turntable, tonearm, or cartridge combinations at the push of a button, without any reconfiguration

Fully-balanced circuitry rejects noise and keeps the delicate signal from a phono cartridge in balanced mode, maintaining balanced operation throughout and eliminating noise that would otherwise obscure critical musical information

Entirely separate power supply chassis houses four independent power supplies: left audio, right audio, control, and standby, for total isolation of all supplies from the sensitive analog audio circuitry

Standard RIAA equalization as well as EMI, FFRR (London/Decca), and Columbia EQ selections enable proper playback of collectible records made prior to 1955

Modular and discrete Boulder 995S phono gain stage is exclusive to the 2108, hand-manufactured and calibrated to spec in a potted and precision-machined housing

Non-resonant and expertly machined casework protect the delicate analog signal from microphonic and resonant distortions

Customizable Personality Cards for each input to match the exact individual needs of various phono cartridges: MM, MC, resistive and capacitive loading, high or low gain, and demagnetizing

Switchable outboard demagnetizer pass-through connections for use with specific MC phono cartridges

Front panel selectable, three-setting low-cut filter removes turntable rumble or low frequency noise from warped records
