Application 9: Large Restaurant, Secondary Zones
In this simplified example, a FreeSpace DXA 2120 digital mixer/amplifier
and ZA 190-HZ work together to provide sound to a large restaurant.
The DXA 2120 receives signals from multiple sources and supplies
power to loudspeakers located in the main dining and bar areas. A ZA
190-HZ zone amplifier connects to the DXA 2120 via the fixed-signal
AUX OUTPUT connection. Both components are located in an
equipment room inside the restaurant. The ZA 190-HZ runs a split
constant-voltage distribution line to two zones, each with their own 70V
wall-mounted variable control speaker attenuator (not a Bose part).
These feeds power pairs of DS 16F (16 W tap) loudspeakers in kitchen
and restroom areas.
