The load (Input impedance) for the ADL GT40 is as follows:
Line 50K ohm Approx.
MM 46K ohm Approx.
MC 10K ohm Approx.
Maximum Input Level for MM: 5.0mVrms at 1K Hz
Maximum Input Level for MC: 0.4mVrms at 1K Hz
Maximum Input Level for LINE: 1Vrms at 1K Hz
The Gain setting for the ADL GT40 is fixed at 62.5dB for MC and fixed at 48.5dB for MM.
(MC input to LINE output) => 62.5dB @ 1K Hz , +6dB(Line)
(MM input to LINE output) => 48.5dB @ 1K Hz , +6dB(Line)
GT40 has no setting for gain to match different impedance headphones. We recommend using 16 ohm to 300 ohm impedance headphones.
