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-2 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.

: In order to setup an SC-2 by using its Web Interface you must have the
SC-2 connected to your home Network.

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-2 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-2 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.
