CHAPTER 2: Hardware Component Details
This chapter provides details about the HAL System hardware devices that you'll be installing.
HAL1 Device
The HAL1 host device (which is referred to as HAL throughout this guide) is the
brain
that con-
trols 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 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.
Maximum Device Connections
The device connections that are possible on a HAL1 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
1–4 Expansion Unit Devices (EXPs)
l
8 Mic/Line Inputs
l
8 Line Outputs
l
4 Logic Inputs
l
2 Relay Outputs
Other Functionality
In addition to hosting other hardware devices and managing system operations, HAL also does
the following:
l
Provides power to connected RADs, DRs, and EXPs
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 sys-
tem
