Connections

Digital Audio Connections

Connect an optical cable from each of the Digital Audio 1-4 output connectors to the corresponding sound bar or AVR's audio port.

Product Select Buttons

To select products, connect the push-button to the RJ9 port marked Push-Buttons at each position. To enable TV sound, connect a push-button to the RJ9 header port marked TV Button. Compatible push-buttons are available from Audio Authority.

The modular RJ9 plug makes this Easy Plug button a snap to install and reliable for the life of the demonstration system. RJ9 is the same four-conductor format used for most telephone cords, making the harness easy to obtain in any length. The standard 802-807 harness is 1.5m long, with other lengths available upon request. A Model 013-100 Easy Plug button with an illuminated blue ring is shown.

Timeout Interval

All outputs deselect after a period of inactivity (the timeout interval). The timeout interval is set by the Timeout dial, in increments of 15 seconds. If the timeout switch is set to 0, the demonstration does not time out. Each time a customer makes a selection, the timer resets.

Timeout Dial: A circular dial with numbers 0 through 9, labeled 'TIMEOUT DIAL', used to set the demonstration timeout interval.

HDMI Input

Connect a premium certified high-speed HDMI cable from the source to the HDMI input of the 1729-4K. Cable lengths should be kept as short as possible.

Television Output

Connect the output of the 1729-4K to the TV input with a premium certified high-speed HDMI cable.

Power

Connect the included 12V power adapter to the Power Input of the 1729-4K. Button LEDs should be on. If these lights are not on, check the HDMI cable connections, ensure both HDMI cables are connected to the 1729-4K, and verify the components are powered.

Operation

On power up, the POWER light blinks to show normal operation. Turn on the source and destination devices. Both HDMI cables must be connected for operation. Press a product select button to make a selection. Press the TV button; the demo product mutes, and the TV speakers play. Deselect any active product by pressing the button again.
