used.
C Remote
Trigger
Input
The remote trigger input is used for remote activation of the
RA2400/RA7300
by an external
device. The trigger is used to connect in a separate device in the system so when it powers on
it also powers on the
RA2400/RA7300.
Use
the
Remote Trigger jack to connect a compatible preamp, source device or other product
(with a 3.3-24VDC output) that that you wish to use to remotely power on the
RA2400/RA7300.
D Speaker Outputs
Use the Speaker Output binding posts to connect the
RA2400/RA7300
to your speakers. The
binding posts are color coded to help ensure proper polarity.
E Product Serial Number
Document this number for future reference or when contacting Datasat customer
service/techsupport. You will be required to provide the serial number when reporting issues
and/or to verify warranty.
F AC
Input
Use the included power cord(s) to connect your amplifier to an AC power source. The RA2400
uses one power cord and the RA7300 uses two.
G Master
Power
Switch
The rear panel Master Power switch(es) selects power to the amplifier, either on and off. The
switch(es) must be in the ON position for the front panel power switch and remote trigger to
work. Note the RA2400 has one master power switch and the RA7300 has two (both should
either be on or off).
H DB25 Analog Audio Pass-Thru 1-8 Connector
This connector routes signals from the DB25 input jack, through the
RA2400/RA7300
for
connection to additional amplifiers. For example, the Subwoofer input channel can be switched
away from the RA2400/RA7300 and still be routed to the pass-thru connector. This allows the
Subwoofer signal to be fed to a separate amplifier. Also, the 8-channel analog audio output
from the Datasat RS20i can be routed to multiple RA2400/RA7300 amplifiers.
I Power Supply Voltage Indicator
Each RA2400/RA7300 is marked at the factory by a green dot to indicate the power
requirements. Be certain to use only the appropriate voltage as marked. Plugging an 117V
