The following section provides instructions to access the AM-77’s advanced features.
3a. Labeling of Inputs and Setting Level Offset
With the AM-77, in one process, it is possible to label each of the 5 inputs with a corresponding source and to set
the respective level offset. This function is recommended only after ALL desired sources have been connected
to the AM-77.
A list of available labels is shown overleaf in chronological order.
The main advantage of setting the level offset is that the volume level will change in real-time, so that the user
may adjust the offset without the need for additional equipment. By using this function and selecting the desired
level offset, one may ‘match’ the volume level of all inputs so that when switching between sources, the volume
remains the same, thereby avoiding undesirable and potentially equipment-damaging noise levels.
For example:
Input 1 CD Player (2V output) Offset: 0dB
Input 2 LP (1V output) Offset: +6dB
Input 3 SACD Player (4V output) Offset: -6dB
