Phono/RIAA:

The SRL Phono Stage MK2 is based on a dual-stage circuit gain with a standard, passive RIAA equalization. Uses modern, low-noise, operational audio amplifiers. Allows the use of MM, Moving Magnet or MC, Moving Coil elements.

Power Supplies:

Its six independent power supplies use Schottky rectifiers, with independent power and current sources for each loop without stabilization feedback. The total capacitance of the power supply is 11,200 uF.

Design:

The SRL Phono Stage MK2 is focused on a minimalist and functional design. The panel is made of anodized aluminum or acrylic - and the chassis in carbon steel, where it is applied thick layer of electrostatic paint in black matte. Internally several elements are used to prevent the formation of hysteresis loops on the chassis.

The transformer, manufactured under strict specification, uses plate type G.O. (grain oriented), electrostatic / electromagnetic shielding and separate secondaries to the audio and service power supplies (timing, relays and lamps).

The unit is available in three versions: RCA, XLR, and XLR Premium.
