A. Local Power (see figure 3-3).
In this system, power is supplied to the
AR2000-M device by connecting it to a 120VAC or
240VAC supply in the immediate vicinity of the
device. An input selector switch is provided and must
be set to the appropriate input voltage prior to
turning the device on.
3-7. POWER CONNECTIONS.
The two basic methods of supplying power to an
Audio Router device are 120VAC 50/60Hz Local
Power or 240VAC 50/60Hz Local Power and 24VDC
Backup Power. The following paragraphs describe
each method along with the advantages and disad-
vantages of each.
