The GT40α gets you to the winner’s circle!!
The GT40α is built for enthusiasts with growing music collections on their computer hard drives. It’s a high-performance 24bits/192kHz USB DAC that’s amazingly affordable. Looking to convert your LPs or other analog sources to digital? The GT40α will take you to the podium with every album you archive.
The seriously-shielded audiophile-grade GT40α features a low-latency USB 2.0 audio driver that plays and records at 24bits/192kHz. A likely first for this category, the GT40α includes a built-in low-noise MM / MC phono preamp! Record your favorite vinyl to hard disk via the USB output.
The ADL GT40α features L/R analog outputs, and switchable line or phono inputs with a vivid, captivating sound that is simply unheard of in this category.
The ADL GT40α (wired with ADL’s Formula 2 cable of course!) brings Furutech’s signature sound — smooth, detailed clarity — to desktop systems, especially with high resolution 24bits/192kHz files, but even 16-bit/44.1kHz files sound impeccable and very musical.

IMPORTANT:
The load (Input Impedance) for the ADL GT40α is fixed at 47K ohm for MM and 100 ohms for MC
Input Sensitivity Level for MM: 4.0mVrms at 1K Hz
Input Sensitivity Level for MC: 0.4mVrms at 1K Hz
Input Sensitivity Level for LINE: 400mVrms at 1K Hz
Maximum Input Level for LINE: 2Vrms at 1K Hz
MC input to LINE output (Vol./Max.) => 70dB @ 1K Hz ,( +/-1dB)
MM input to LINE output (Vol./Max.) => 50dB @ 1K Hz ,( +/-1dB)
LINE input to LINE output (Vol./Max.) => 8dB @ 1K Hz ,( +/-1dB)
GT40α has no setting for gain to match different impedance headphones.
We recommend using 16 ohms to 300-ohm impedance headphones.
