GT40a Windows driver supports Win XP, Win 7 and Win 8 (not Win Vista)
The load (Input Impedance) for the ADL GT40α 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)
GT40α has no setting for gain to match different impedance headphones.
We recommend using 16 ohm to 300 ohm impedance headphones.
