ACT-2
Audio Coupling Transformer
General
The ACT-2 Audio Coupling Transformer is used with the DVC-AO/RM-1 and AA-30, AA-100, or AA-120 to provide a means to drive multiple amplifiers in large audio system applications. It provides the following functions:
- Attenuates high-level amplifier output to create low-level input for additional amplifiers.
- Isolates input from output.
- Provides CMNR (Common Mode Noise Rejection).
Suitable Configurations
To drive AA-120/120E, AA-100, and/or AA-30/30E audio amplifiers: The ACT-2 provides electrical isolation between its input and output and attenuates the signal from high-level audio to low-level audio. Ground fault detection is not provided for output wiring on the ACT-2. Up to 40 audio amplifiers may be fed by the output of an ACT-2 as long as the wiring does not exceed 200 feet (61 meters), 18 to 12 AWG (0.78 to 3.1 mm²). The DVC-AO/RM-1 low-level signal is first fed into a single AA-30 amplifier. The high-level output of this amplifier will support a Class A or Class B wiring arrangement and can be fed to the input of up to 500 ACT-2 units. The outputs of each of the 500 ACT-2 transformers may then be used to feed a lowlevel audio signal to the input of as many as 40 additional AA Series amplifiers. The output of an ACT-2 supports Class B wiring only. Where Class A wiring is required, all amplifiers served by an ACT-2 must be housed in the enclosure containing the ACT-2.
