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.
