Section 3: DAX Digital Audio Amplifiers
3.1 DAX Overview
3.1.1 Description
These Digital Audio Amplifiers are multi-featured amplifiers with digital audio functionality. They
are designed to work with the DVC Digital Voice Command.
Refer to Figure 1.1 on page 9 for a simplified illustration of DAL devices on a digital audio loop.
3.1.2 Features
The DAX audio amplifiers have the following features:
• 50W total output power at 25V
RMS
(DAX-5025) or 70 V
RMS
(DAX-5070).
• 35W total output power at 25V
RMS
(DAX-3525) or 70 V
RMS
(DAX-3570).
• One Class A connection for high-level audio output, or alternately, two Class B connections.
• Audio output activation via network control-by-event equations resident within the DVC.
• Isolated alarm bus input, to be used for backup activation of alarm messages when normal
digital communication is lost, or for retrofit applications.
NOTE: The term DAX is used in this manual to refer to all the DAX model versions listed in
Table 3.1.
Individual part numbers are used to distinguish features or functions that differ.

NOTE:
Speaker placement must be given careful consideration when planning an audio system:
• Place speakers from different DALs (Digital Audio Loops) so they are not within the audible
areas of other DALs.
• Carefully consider the audible range of speakers within a DAL; overlapping audio messages can
be confusing.
