Using single-ended preamplifiers:
If your preamplifier/processor does not have balanced outputs, the adapter used to
convert from balanced to single-ended should tie Pin 1 and Pin 3 (the inverted
signal) together. This can easily be checked with an ohmmeter: the resistance
between Pin 1 and Pin 3 should approach zero.
CAUTION!
The Single Ended to Balanced adapter on the input side of the SC-3 is
wired differently than the appropriate adapter on the output side. Please refer to the
output section of this manual (section 7.) for connecting to Single Ended Amplifiers.
As mentioned above if you have a single-ended unbalanced preamp/surround
processor we recommend purchasing one of our premium custom
WWK-
CUSTOM2 and or WWK-CUSTOM3 interconnect kits that can be made with either
balanced and or unbalanced connections.

RS232
The RS232 interface allows an external control system such as AMX, Control4,
Crestron, or Savant to control the system. All basic operational modes are supported
(operate, standby, selecting presets).
Connection Specification:
The RS232 DB-9 female connector is wired as a DCE, and connects via straight
cable to a DTE, or via null modem/crossover cable to another DCE.
The Pinout:
•
Pin 2 is the TRANSMIT for data from the SC-3 System Controller to the
control system and carries RS232 signal name RxD.
•
Pin 3 is the RECEIVE for data from the control system to the SC-3 and carries
RS232 signal name TxD.
•
Pin 5 is the GROUND/COMMON for the pin 2 and pin 3 signals.
•
The other pins are not connected; the shell is grounded at the chassis.
Signal names RxD and TxD are named from the point of view of the DTE and that is
why the signal names appear to be backward but are not per the standard. Off the
shelf USB RS232 Adapters plug right into the port and work as expected with no
special configuration.
Communication parameters are:
•
Baud Rate: 9600
•
Bits: 8
•
Parity: None
•
Stop Bits: 1
