Rane HAL4 1U Programmable DSP Multiprocessor, 2 Input x 2 Output Audio, 20-20kHz, 2.9kOhms, 2100 MIPS

The HAL4 is a stand-alone 2x2 Halogen replacement for the popular DragNet RPM2 with four-times the processing power, improved digital remote and Web Control options, simplified linking and improved preset recall capability. It solves just about every signal processing problem found in one or two rooms. The HAL4 is a 2-Input, 2-Output drag-and-drop DSP device for Halogen software. Inputs are Line / Line-Plus / Mic / Mic+48V capable. In addition to supporting balanced line and microphone inputs, this configuration allows a stereo pair connection to an input, converting to a single L+R mono signal. Standard balanced outputs are provided.

• DSP contains 2100 MIPS of processing power
• Ethernet 1000BASE-T with Zeroconf service discovery protocol for easy set up
• 2 analog Line-Plus Inputs on Euroblock connectors (green)
• "Mic / Line-Plus" Inputs accept a balanced mic, line or mono left & right unbalanced lines, configured in Halogen software.
• 48V phantom power available for a condenser mic input.
• 2 analog balanced line outputs on Euroblock connectors (orange)
• Front panel signal and overload indicators for both inputs and outputs
• One Digital Remote Port
• RJ-45 shielded CAT 5e connections up to 300 meters (1000 feet) A single DR port provides support for preset recall, level control and select functions using a DR1, DR2 or DR3. If more logic ins and outs are needed for pots, switches or external indicators, a DR4 or DR5 may be added.

RADs (Remote Audio Devices)
A Remote Audio Device (RAD) provides analog to digital conversion at the wall.

• RADs greatly reduce the length of the analog transmission line.
• Remove the hum and buzz problems of long runs.
• Reduces the cost of wiring, conduit and termination.
• Most models install in a standard USA electrical box.
• Print labels for each in/out from Halogen software.
• Most models are available in white, ivory and black and include a matching decora plate. To order a RAD4 in white, order a RAD4W ... ivory is a RAD4I and black is a RAD4B.

Digital Remotes
Three Digital Remotes simplify end user control and eliminate installer brain fatigue. Use Digital Remotes for volume control, preset recall, source selection or resetting or toggling system states. All offer customizable backlit LCD screens for intuitive end user labeling. Home run shielded CAT 5e (or better) connections to a HAL or EXP eliminate addressing, external power and the need to test the cables. Each is available in white, ivory or black and fit in standard electrical boxes.

• The DR1 supports Level Control.
• The DR2 offers Single Selector or List of Toggles/Commands behavior.
• The DR3 has three behaviors: Single Level & List of Toggles/Commands, List of Levels for either multizone volume control and/or input source mixing and Single Level plus Selector.

The DR4 Logic I/O Expander adds more logic to any HAL for external switches and pots:
• 8 Logic Inputs, Internal 5V pull-up.
• 8 Logic Outputs for relay drive, LED or logic level output.
• 8 Analog Control ADC inputs for potentiometers.
• 6 IR Ports for IR2 wall sensors.

The DR5 Switch Controller adds more logic to any HAL, accepting external switches and driving LEDs on a room combine panel.

Ethernet, RAD and DR Cable Lengths
The maximum length for CAT 5e cable between Ethernet devices is 100 meters. Shielded CAT 5e between a HAL or EXP and a RAD (carrying 4 channels of digital audio) can run up to 150 meters. Shielded CAT 5e between a HAL or EXP and a DR (carrying control information) can run up to 300 meters. It is possible to extend these lengths by increasing distance between the HAL and Expanders. Up to 32 Expanders can daisy-chain from a single HAL and each can be up to 100 meters apart. For greater distance, off-the shelf Gbit Ethernet media converters are supported. Multimode fiber can run up to 2 kilometers and singlemode fiber can run up to 12 kilometers.
