DA2208 can be used for various applications, such as :
- distribution of single audio signal to multiple units of power amplifiers
- distribution of audio signal from one location to multiple sites
- tone controls of various locations according to lestening taste from single audio source
- PA application in uninterrupted paging system
Typical schematics for audio distribution from single / double source to multiple units of
amplifiers.

MX2222 Pre-amplifier mixer
BGM output to Group B input
mixed output to Group A input
BGM amplifiers
Paging amplifiers
Group B output
Group A output
to speaker zone selector - amperes zs5602
balanced line output
Note :
Use DA2208 when the output from a mixer ( or any other source ) is to be linked to many
amplifiers ( typicall exceeding 6 units ). Otherwise it shall not be required and can be fed to
amplifier inputs directly from mixer.
Schematic illustrates the
setup for uninterrupted
paging system, with dual
audio signals are to be
connected to 2 sets of
amplifiers.
