Step 4 — Outputs

a. Video and sync BMEs — Connect a single plane of video or sync, as appropriate to the BME, to the BNC connectors on the video and sync BMEs for each output.

NEach BME supports one video or sync plane only. See figure 1-1 in chapter 1 for an example configuration.

b. Audio BME — Connect balanced or unbalanced stereo audio or mono audio devices, as appropriate to the BME type, to the captive screw connectors.

Front Panel Controls

Input and output buttons select inputs and outputs. Output buttons light amber to indicate video and audio ties. The buttons light green to indicate video-only ties. The buttons light red to indicate audio-only ties. Input and output buttons also select presets.

The output buttons also display the selected input’s audio level.

The input buttons also display the selected output’s volume level.

Enter button saves changes.

Preset button saves a configuration as a preset or recalls a previously-defined preset.

View button selects a view-only mode that prevents inadvertent configuration changes. In systems with audio BMEs, View decrements the level and volume.

Esc button cancels selections in progress and resets the front panel button indications. The Esc button does not reset: the current configuration, the RGBHV and audio selection, any presets, or any audio level or volume settings. In systems with audio BMEs, Esc increments the level and volume.

RGBHV and Audio buttons select/deselect video and/or audio. The Audio button blinks to indicate audio breakaway. The Audio button also selects the audio level/adjust mode.
