Using DAX88 Pre-Amp Outputs
Zone 7 and 8 of the DAX88 are pre-out zones and are represented on the back of the
unit as stereo RCA jacks. These zones can be used for connecting external amplifiers
to expand the available power in a large zone or multiple zones, or can even be used to
add a powered subwoofer to a room. These outputs could even be used to feed an
audio signal into another DAX88 unit.
The DAX88 can be used as the master controller in large commercial audio systems
with constant voltage 25/70V amplifiers connected to these PRE-AMP outputs. The
PRE-AMP output levels are variable and are controlled from the Matrio App, DAX88
keypad or even RS232 from an automation system. For best performance, the PRE-AMP
output cables should be less than 25 feet long and be high-quality, shielded cables.
