DAX Installation DAX Digital Audio Amplifiers
In Riser Mode to Additional Amplifiers
When a DAX’s Speaker Riser Mode is programmed R
ISER TO ADDITIONAL AMPLIFIERS (refer to
the DVC Digital Voice Command manual for programming), the amplified signal from the DAX
may be connected to an ACT-25 or ACT-70 Audio Coupling Transformer to drive additional AA-
Series amplifiers. This mode provides a 200 Hz supervisory tone required by analog amplifiers.
Figure 3.16 DAX Riser Mode to Additional Amplifiers
Refer to the the ACT-25 and ACT-70 installation documents for more information.
In Riser Mode to Control Modules
When a DAX’s Speaker Riser Mode is programmed R
ISER TO CONTROL MODULES (refer to the DVC
Digital Voice Command manual for programming), the amplified signal from the DAX may be
routed to multiple speaker circuits using SLC control modules.
Do not use background music in this mode. The DAX will provide speaker circuit supervision only
when idle.
