2.5.5 AIB-4/AIB-1 and ACT-2
The ACT-2 Audio Coupling Transformer provides a means to drive a large number of remote audio
amplifiers in large system applications. It isolates inputs from outputs and also provides common
mode noise rejection. Refer to the ACT-2 Product Installation Document for detailed information.
Note: When using the ACT-2, it must be installed on an AIB-4/AIB-1 which is mounted only in the
top row of the cabinet. The ACT-2 will not fit in any other cabinet position.
