in the diagram at right.

b. Connect the left stereo channels of the audio sources to

one or both white RCA Audio Input connectors.

Connect the right stereo channels of the audio input

sources to one or both red RCA Audio Input connectors.

Step 5 — Connect audio outputs

a. Wire the RCA audio output connectors to audio output devices as

shown in step 4a, above.

b. Connect the left stereo audio channels of the output devices to one

or both white RCA Audio Output connectors.

Connect the right stereo audio channels of the output devices to

one or both red RCA Audio Output connectors.

Step 6 — Wire the power connector (optional)

C Always use a power supply speciﬁed by Extron for the YCS SW2 A. Use of

an unauthorized power supply voids all regulatory compliance certiﬁcation

and may cause damage to the supply and the YCS.

Step 7 — Enable auto-input switching (optional)

To set up the YCS to automatically select the active, connected input:

a. Use two jumper wires to connect pins 1 and 2 and pins 2 and

3 of the provided 3-pin captive screw connector. Tighten the

screws to hold the jumper wires securely in place.

b. Insert the captive screw plug into the Contact/Auto-SW

connector as shown at right.

Step 8 — Enable black and white mode (optional)

To enable the YCS to detect NTSC signals that are black and white only, place the switcher in

black and white mode as follows:

a. Remove the four case screws on the sides of the

unit and lift off the top cover.

b. Locate the jumper at JMP1 and SW1 on the YCS

internal board (behind the front panel buttons).

Place the jumper onto both the SW1 and JMP1

pins.

C When placing the jumper on the two

pins, ensure that the ﬁne wire connecting

the two sleeves of the jumper is at the top

(outside). Do not attempt to force the

pins through the wire.

c. Replace the case cover.

Step 9 — Power on

Apply power to the YCS, the input sources, and the output devices.

Selecting Inputs by Contact Closure

The Contact/Auto-SW connector on the YCS rear panel enables optional remote input

switching via a latching contact closure device (as

an alternative to auto-input switching, described in

step 7, above).

To switch inputs using contact closure:

a. Connect a latching contact closure device to

pins 1, 2, and _ of the Contact/Auto-SW

connector on the rear panel.

b. To select input 1, momentarily short pin 1 to

the _ pin. To select input 2, momentarily short

pin 2 to the _ pin.
