HAL3s Multiprocessor

HAL3s Multiprocessor
HAL3s Multiprocessor

Rane has replaced the HAL3 model with the updated HAL3s. The HAL3s does everything the HAL3 did, and more!

  • New analog Mic/Line-Plus input stage adds support for 2 microphone inputs, with or without 48 V phantom power.
  • Additional RAD port: one DR port becomes a RAD port. This makes the HAL3s a 6-input, 10-output DSP (the HAL3 was 4 x 8). More audio channels means more applications solved.
  • 10 dB quieter: the dynamic range is improved 10 dB — now with 108 dB dynamic range!
  • Best of all, the new HAL3s has the same price as the HAL3 was.

Note that your existing HAL3 software configuration files are not compatible with the new HAL3s. This means system designers should either create brand new HAL3s files to use with the new model, or copy and paste all the HAL3 DSP blocks and wires into a new HAL3s file. Then recreate links, presets or paging management settings. You’ll find HAL3s support in the latest version of Halogen software.
The new HAL3s Multiprocessor is shipping now!


A HAL3s Multiprocessor supports 6 in x 10 out audio, with 2 in x 6 out on balanced analog connections, and another 4 in x 4 out digitally through RADs. The two analog 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.

Two DR ports 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. DRs can be operated from a RAD port, so up to four DRs can plug into a HAL3s when RADs aren't needed.

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 US 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.

All RADs

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.

The DR6 is a fully customizable touchscreen remote for the HAL family. It supports multiple pages or tabs and any set of levels, toggles, selectors and/or commands on the 7-inch LCD display.

Ethernet, RAD and DR Cable Lengths

CAT5e 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.

Restaurant and Bar Music and Paging Example

HAL3s Example System

Restaurant system notes

  • The 2 Mic / Line-Plus Inputs (green) may be wired as -10 dBV unbalanced Left/Right Monoed to mix the stereo output for a mono background music system. Or, a single stereo device can supply inputs 1 and 2 for a stereo system.
  • A RAD14 located in the bar adds 1 optional mic, an easy place to plug in a phone or tablet to play MP3s or internet radio, and provides two balanced outputs for remote powered speakers that can be unplugged and put away when not in use.
  • The PAGER1 is located near the entrance with presets to:
    • Page the bar when a table is ready in the restaurant,
    • Page the restaurant when someone is needed at the bar.
    • Page the entire restaurant.
  • DR3 Source and Level Remotes are located in each area, with easy independent source selection and volume.
  • A simple analog switch is provided in the kitchen to turn music on or off. An SPDT switch could select which source is played.
  • MA4 Multichannel Amplifier provides four channels @ 100W, and the MT4 provides transformers for distributed speakers.

Live Sound Club Example

HAL3s Live Sound Example System

Club system notes

  • Either RAD15 with XLRs could be a RAD16 with Euroblock connectors. The RAD15 has instant connectivity, and the RAD16 has the advantage of mic- or line-level inputs in more permanent installations.
  • The DR3 allows control either from the stage or the rear of house.

3-Zone Stereo Background Music Example

HAL3s Background Music Example System

This background music system supplies stereo audio in three rooms, each with it's own source selector and volume control. One stereo source is fed to the "Line" inputs on the rear of the HAL3s wired + and ground for each channel. Two sources could be used if they are run in mono, wired the "Line-Plus" method of Left+, Right+, and ground. Another input can be away from the HAL3s in it's own room to accept an accessory input like a phone or bluetooth adaptor.
