CHAPTER 2: Introduction to the HAL System Overview of HAL Devices The HAL host device (which is referred to as HAL throughout this guide) is the brain that controls the entire HAL System. It can connect to a variety of other hardware (or slave devices) such as analog equipment, RADs, DRs, and EXPs. Inside the HAL hardware is a DSP audio processing engine and a host controller that controls DSP operations and manages control links, presets, and more. There is only one HAL device per system. You cannot connect one HAL to another. NOTE FOR DRAG NET USERS: The DSP processing engine in the HAL1 device is four times more powerful than the RPM88, the HAL2 has twice the power as the RPM88, and the HAL3, HAL3s, and HAL4 have the same amount of DSP processing power as the RPM88. Other Functionality In addition to hosting other hardware devices and managing system operations, HAL also does the following: l Provides power to connected RADs, and DRs l Stores configuration settings and compatible firmware for itself and for each connected RAD, DR, and EXP l Provides a connection to an Ethernet network (for control of HAL and the connected devices) l Displays various status indicators (LEDs) providing information about the health of the system Available HAL Models The following HAL models are currently available. For the most current list of HAL models, see the Rane website. HAL1x The device connections that are possible on a HAL1x are as follows: l 4 Remote Audio Devices (RADs) l 8 Digital Remotes (DRs)-Can add up to 4 more by plugging them into the RAD ports l 1-32 Expansion Unit Devices (EXPs) (CAT 5e Expansion Bus) l 8 Mic/Line Inputs l 8 Line Outputs l 4 Logic Inputs l 2 Relay Outputs HAL2 The device connections that are possible on a HAL2 are as follows: l 4 Remote Audio Devices (RADs) l 4 Digital Remotes (DRs)-Can add up to 4 more by plugging them into the RAD ports l 4 IR Remotes l 8 Mic/Line Inputs l 8 Line Outputs l 1 AES3 Stereo Input l 1 AES3 Stereo Output 11
