Powerful Preamplifier Functionality
As a G2.1 Series product, ALTAIR G2.1 has been developed with properties and features that ensure its performance is considered “next-level,” and allow for it to be used as a stand-alone preamplifier. Analog Volume Control onboard, similar to that on the VEGA G2.1 and based on a resistive ladder design, provides an ultra-quiet signal, no matter the input. Class A Orfeo Output Modules allow for an ultra-low-noise and low-distortion signal in the analog domain. Altair G2.1 also houses two separate all-analog inputs, completely bypassing the digital structure and maintaining a pure analog signal from input to out. The first is a line-level analog input, including home theatre bypass functionality, and the second is an in-house engineered moving-magnet phono stage for an elegant, direct, and quiet connection to a turntable.
