Rane HAL4 Programmable DSP Audio Distribution Multiprocessor

The HAL4 Programmable DSP Audio Distribution Multiprocessor from Rane allows you to easily create a network of audio and paging zones. It has 2100 MIPS of processing power, and includes its own Halogen control software for Windows, which assists in everything from dynamic signal routing to cable testing.

The HAL4 provides two on-board analog inputs and outputs in Euroblock format. Each input supports a dynamic mic, 48V phantom mic, +4 dBu line-level, or Rane's line-plus input. The line-plus mode accepts -10 dB unbalanced left/right monoed together on the "+" and "-" ports respectively. Line-plus also connects the stereo RCA left tip to the "+" terminal, the RCA right tip to the "-" terminal, and both RCA shields to the Euroblock ground.

The HAL4 offers a single DR remote port, which can control parameters such as volume, DSP presets, input source, and system states. The unit may be connected to the DR1, DR2, DR3 or DR6. Additionally, a DR4 or DR5 may be added for other logic inputs and outputs. The remote connects via CAT 5e cable at lengths up to 1000 feet (300 m).

The Halogen software enables complete control of all components networked to the HAL4 from an Ethernet-connected Windows-based PC. It's indispensable in designing, configuring, and dynamically controlling your HAL audio system. It splits your workflow into two sections, hardware and processing. The hardware workspace allows you to see all connected devices, specify them, and troubleshoot. The processing workspace is where all the virtual patching, DSP effects processing, preset design/recall, zone link, and room combination settings take place. The system can also support external control systems, such as AMX, Crestron, and Stardraw. The HAL4 ships with the Halogen software and a standard IEC power cable.
