Inputs
There are two types of audio input connections:
●
XLR type input jacks can be used to connect to the outputs of a preamplifier, receiver with
preamp-out connectors or other sound source devices for the RA2400/RA7300.
●
DB25 “balanced analog audio in 1-8” connector is used to connect the Datasat RS20i (home
cinema audio processor) output to the RA2400/RA7300. A DB25 cable is included with the
RA2400/RA7300.
B DB25 “Balanced Analog Audio In 1-8” Connector Selector Switches
The selector switches are used for channel assignment when the DB25 “balanced analog audio in
1-8” input connector and cable are used with the RS20i. For easy reference, use the white
rectangles next to the switches to write in channel labels.
Note: The selector switches can be used to bypass the Subwoofer channel (input from DB25
“balanced analog audio in 1-8”) from the RA2400/RA7300. Since the selector switches do not
affect the DB25 “analog audio pass thru 1-8” connector, the Subwoofer signal (fed to the input
connector) can be connected to a separate self-powered subwoofer amplifier. The selector
switches can also be used route input signals when multiple RA2400/RA7300 amplifiers are
