Phono Stage

The flagship of the DS Audio line, the DS Master1’s phono stage is a fully discrete dual-mono design with single-ended RCA and balanced XLR outputs, as well as three low frequency cutoff points.

Fully discrete dual-mono circuitry with three dedicated power supplies

The DS Master1’s matching phono stage features expertly designed, fully independent dual-mono analog circuits. To achieve flagship-level performance, each channel has its own dedicated power supply to deliver more than ample power with the third power supply dedicated to the cartridge LED drive system to the DS Master1 phono cartridge.

Your choice of outputs and low frequency response

The DS Master1 phono stage features three sets of RCA or XLR outputs. As well as three separate low frequency cut-off points. Output 1 is “DS Standard” single cut-off with 6db/oct at 30Hz. Output 2 is “RIAA Standard” double cut-off with 6db/octave 50.5Hz and 6db/octave at 30Hz. Output 3 is “RIAA Sub-sonic” triple cut-off with 6db/octave 50.5Hz, 6db/octave at 30Hz, and 12db/octave at 25Hz. Each low frequency contour is accessed by its own dedicated single-ended RCA or balanced XLR output for a total of six sets of dual-mono outputs.

Massive 24 kilogram / 53 pound unit weight

Its robust weight is the result of the twelve 120K μf electrolytic capacitors and three transformers used in the DS Master1 phono stage. To achieve the lowest possible impedance, a pure copper bus-bar provide connection between the bank of capacitors.

*Please note, the DS Master1 phono stage is only compatible with DS Audio optical phono cartridges
