C Do not tin the stripped power supply leads before
attaching the captive screw plug to them. Tinned
wires are not as secure in the captive screw
connectors and can be easily pulled out. They may
also break after being bent several times.
W The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
Audio Connectors
The YCS SW2 A has six RCA audio connectors: two left channel
inputs (white), two right channel inputs (red), one left output
(white) and one right output (red). Figure 2-12 shows the pinout
of the RCA audio connectors.

Wiring the Power Connector
If using a different external power supply from the one provided
with the YCS, you may need to wire the connector for it.
To wire the power connector,
1
. Cut the DC output cord to the length needed.
2 . Strip the jacket to expose 3/16 inch (5 mm) of the
conductors.
C Exposing more than 3/16” (5 mm) of the copper
wires could allow the stripped wires to touch each
other, causing a short circuit. This could result in
the external DC power supply overheating and/or
burning.
Stripping the wires to expose less than the
recommended amount may cause them to slide out
of the connector too easily, even if they are tightly
pinched by the captive screws.
3 . Slide the leads into the supplied 2-pin captive screw plug
and secure them, using an Extron Tweeker or other small
screwdriver.
4 . To verify the power cord’s polarity before connecting
it, plug in the power supply with no load and check the
output with a voltmeter.
The figure on the next page shows how to wire the connector.
