4.1 Labelling of Inputs and Setting Level Offset
With the AM-777, in one process, it is possible to label each of the 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-777.

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
The following steps outline the procedure to label all the inputs and set the respective level offset.
