EXP3x Device

Each EXP3x output supports one of two selectable fixed configurations: A Zone Output configuration and a Line Output configuration. The only difference is that the Line Output omits the Zone Processor and Emergency Zone blocks from the processing chain. The reason for including two output configurations is some applications don't require Zone Processing, which provides support for Paging and the Distributed Program Bus. An example is using the EXP3x for analog Line Outputs in a Room Combine configuration, where the Room Combine block in the HAL1x already provides support for Paging and the Distributed Program Bus.

The following sections describe each of the output configurations:

The EXP3x features two RAD ports that provide local support for AV I/O or additional DRs. Some typical applications for the RAD ports are as follows:

• Pager1 Input
• Line Inputs from performance stage located in local zone cluster
• Juke Box input
• AV input from television/satellite feed
• System output(s) to performance stage
• Additional AV output from system to Bar area or digital signage feed
• System output(s) to filler zone with local amps (Zone processing provided in HAL1x)
• Additional DR port(s)

The EXP3x features six DR ports for support of remote level control, source selection, command and toggles. Typical DR port applications are as follows:

• DR1 for individual zone volume control
• DR2 for individual source selection or commands/toggles

  note: You can use Toggles/Command for preset recall, wall open/close, etc.

• DR3 for multi-zone volume control or single volume with source selection or single volume with Toggles/Commands

tip: Place a DR1 in locations where only volume needs to be controlled from within a zone.

tip: Use a DR3 within a zone if you require both volume and source selection. In addition, place a DR3 at a station that needs to independently control the volume of up to 20 zones.

tip: Use a DR2 for global source selection or to indicate a room configuration such as room combining or for Preset Recall.

Eight open-drain logic output ports are provided. These operate the same as logic output ports found on the DR4.

You can configure each of the eight output ports in one of two ways:

• Toggle: The Toggle configuration allows the state of a toggle control in the Control palette of the Processing Workspace to control the state of the Logic Out port. When the toggle control is unchecked, HAL sets the corresponding EXP3x Logic Out port to logic high (5 V) and when the toggle is checked, it sets the port to logic low (0 V). See the EXP3x data sheet for more details on electrical specifications for the EXP3x Logic Out ports.
• Selector: The Selector configuration allows the state of a two position selector control in the Control palette of the Processing Workspace to control the state of the Logic Out port. For example, the logic output can signal a control system logic input that a preset is active or a wall is currently open. When the selector control is set to the first selection, HAL sets the corresponding EXP3x Logic Out port to logic high (5 V). Conversely, when the selector control is in the second position, HAL sets the port to logic low (0 v). See the EXP3x data sheet for more details on electrical specifications for the EXP3x Logic Out ports.

The logic outputs on the EXP3x are suited for legacy paging systems where relays within each zone must bypass 70/100 volt volume controls during a page. This turns up the remote’s volume during pages. With 8 logic outputs, 8 zones of old school constant voltage paging are supported. In this application, logic ports are linked to page-active indicators in Paging Manager in the normal manor [see paging manager and Linking].
