Notes: 1. This specification is guaranteed by characterization, not production testing.
2. Input resistance is for the input selected. Non-selected inputs have a very high (>1MΩ) input resistance.
3. Operation in Slave sub-modes may yield results lower than the 80 dB minimum.
* Parameter definitions are given at the end of this data sheet.
