CHAPTER 2: Introduction to the HAL System When using an EXP3x in a Room Combine configuration, it is typical to provide a DR3 remote in each base room for Level and Source selection. If eight base rooms each require a DR3 device, you can use the 6 DR and 2 RAD ports on the EXP3x for connecting the required eight DR3 devices. Note that you would link to the Level and Selector in each HAL1x Room Processor block and not to controls in the EXP3x. BEST PRACTICE: Use a linkable level block before the EXP3x Input to control the background music level without affecting paging provided before the EXP3x, i.e., in a room processor or zone processor in the HAL device. RAD Ports 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: l Pager1 Input l Line Inputs from performance stage located in local zone cluster l Juke Box input l AV input from television/satellite feed l System output(s) to performance stage l Additional AV output from system to Bar area or digital signage feed l System output(s) to filler zone with local amps (Zone processing provided in HAL1x) l Additional DR port(s) DR Ports The EXP3x features six DR ports for support of remote level control, source selection, command and toggles. Typical DR port applications are as follows: l DR1 for individual zone volume control l DR2 for individual source selection or commands/toggles NOTE: You can use Toggles/Command for preset recall, wall open/close, etc. l 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. Logic Outputs 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: 76
