To listen to audio during installation, connect the audio outputs to a local amplifier and

speaker. A standard stereo system will suffice, but the lack of differential audio inputs

may make the audio seem degraded. After the DSR-4530 is authorized and providing

the desired service, reconnect these outputs to the channel modulator. Since these are

differential pairs, it is recommended to use two pair shielded audio cables rather than

the single wire and shield type.

NOTE:For best quality audio, take care to ground the shield on both the IRD GND ter-

minal and at the channel modulator end.

5. To set up the IRD for use in the network, choose one of the following audio

configurations:

a. For services transmitted in stereo and used in your plant as stereo, connect the Left

Audio Out terminals (L+ and L-) to the left audio inputs on the channel modulator,

and connect the Right Audio Out terminals (R+ and R-) to the right audio inputs on

the channel modulator.

b. For services transmitted as a single mono, connect the Left Audio Out terminals

(L+ and L-) to the audio inputs on the channel modulator. Right Audio Out

terminals (R+ and R-) also contain the single mono. For more details about mono

configurations, see “Audio Mix Field” on page 23.

6. DSR-4530s are able to generate cue tones when commanded over the satellite link. If

these internally generated cue tones are used, connect the 600-ohm differential Cue

Tone+ and Cue Tone

- terminals on the DSR-4530 to the device receiving the tones. The

cautions on cable and grounding noted in the audio instructions also apply to cue tones.

7. If using ASI output, select the service that is desired on the output. If PID Aliasing is

turned on, the DSR-4530 only outputs the specified service.

Powering On the DSR-4530

To apply power to the DSR-4530, perform the following steps:

1. Plug the DSR-4530 into a power source and all LEDs on the front panel are illuminated

while the front-panel LCD screen is blank. After approximately 60 seconds, the LEDs

go out and the LCD screen displays a screen similar to the following:

This screen is displayed for only 30 seconds, then the front panel LCD displays the

Main menu.

2. Proceed with the installation and setup using the front panel menus as described in

"Operating the DSR-4530" on page 9.
