The Micro AMP 4/2 has two audio inputs and four headphone outputs arranged in two groups: A1/A2 and B1/B2. Each group can select either audio input.
Buttons BP1 and BP2 control the source for group A1/A2. Buttons BP3 and BP4 control the source for group B1/B2. The source is selected for a pair of headphones, rather than separately for each headphone output.
| Button | Selection |
|---|---|
| BP1 | Input 1 for headphones A1 and A2 |
| BP2 | Input 2 for headphones A1 and A2 |
| BP3 | Input 1 for headphones B1 and B2 |
| BP4 | Input 2 for headphones B1 and B2 |
The source selection push buttons connect to the input contacts on removable terminal blocks. Identify the group A and group B connections on the unit before wiring them. Volume is adjusted separately for each of the four headphone outputs.
