Figure 2-11 — Power connector wiring

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.

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.

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.
