Furutech Alpha Design Labs GT40Ī±Ā DAC With Phonostage
The GT40Ī± built for enthusiasts with growing music collections on their computer hard drives. Itās a high performance 24bits/192kHz USB DAC thatās amazingly affordable. Looking to convert your LPs or other analog sources to digital? The GT40Ī± will take you to the podium with every album you archive.
The seriously-shielded audiophile-grade GT40Ī± features a low-latency USB 2.0 audio driver that plays and records at 24bits/192kHz. A likely first for this category, the GT40Ī± includes a built-in low-noise MM / MC phono preamp! Record your favorite vinyl to hard disk via the USB output.
The ADL GT40Ī± 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 GT40Ī± (wired with ADLās Formula 2 cable of course!) brings Furutechās 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.
- High performance 24bits/192kHz āVIA VT1736 āUSB chip and 24bits/192kHz āCirrus Logic CS4270ā DAC /ADC chip
- Enjoy audio in high resolution at 24bits/192kHz surpassing conventional 16bit/44.1KHz standards
- Incorporates the most trusted driver in professional audio for 24bits/192kHz recording and playback
- External power supply: while a USB-powered device might be convenient, it wonāt develop the power required for high resolution playback, so we designed the GT40Ī± with an external power supply to solve the problem.
- Headphone Amplifier: It contains a high performance āMaxim MAX9722Aā headphone amplifier with ample drive for good headphones
- Analog-to-Digital Converter: The GT40Ī± sports a high-performance ADC IC chip for high resolution recordings via analog inputs including phono, AM/FM radio, or other analog signals.
- Convenient Clip signal Toggle switch for Recording Attenuation: Adjust the recording attenuation to avoid any distortion during recording: 0dB, 6 dB, or 12dB (RecAtt/db signal light comes on when input level exceeds circuit Gain).
- Phono Preamplifier: A first for this class, the GT40Ī± features a phono equalizer for recording your precious LPs. Switch between Moving Magnet (MM) and Moving Coil (MC) or Line input
- Highest Quality Parts: The GT40Ī± features a high quality amplifier and condenser supporting its high performance analog circuit (NJM5532 OPAMPļ¼ for ADC,DAC,Line in and out and NJM2068 OPAMPļ¼ for Phono )
- High End Audio Grade Connections: The GT40Ī± is equipped with gold-plated Teflon-insulated RCA jacks with an extremely high quality aluminum chassis and machined volume knob

The load (Input Impedance) for the ADL GT40Ī± is fixed at 47K ohm for MM and 100 ohm 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)Ā
GT40Ī± has no setting for gain to match different impedance headphones.
We recommend using 16 ohm to 300 ohm impedance headphones.

“Great packaging for a great product with only a small gripe (just because I am in Italy)”
“Thanks for the quick shipping and great packaging, really courier proof! It could have been trown from the sixth floor without being damaged.
My only small gripe is the power supply that came with only the UK imperial adapter and that is of no use outside UK (the three pronged plug). I wish I had received something usable in Italy.”
