Rane RAD26 – The 1-cable drop RAD

If you need a break from reading, just watch this video introduction to the RAD26:

Rane’s new RAD26, a member of Rane’s HAL System provides enough audio and control I/O to support one room in a HAL audio system.

 Applications include:

Halogen 5.0’s FIR Filter Import DSP Block

FIR chainHalogen 5.0’s FIR Import DSP block is available to all four current HAL models.*  The FIR block permits importing finite impulse response (FIR) filter coefficients. To obtain the FIR coefficient’s file, either:

1) Download the applicable FIR file for the loudspeaker from the manufacture’s website – e.g., Fulcrum Acoustics, or

2) Generate the FIR coefficients from measured loudspeaker response data using the software packages that create FIR filters manually:

CAF Group Specifications for Rane Amplifiers

Audio product specifications always seem contentious. But they should be more like Cheerios – they are what they are. The trouble with audio specs is that not all companies follow standards on measuring and especially publishing specifications with the detail required to make them useful. To make valid comparisons between different products, or implement them in systems effectively, the details are imperative. It’s still mostly a free-for-all – especially with the exaggerated “marketing” numbers often seen.CAF Group Continue reading

The Rane PAR – Pro Audio Reference

Highlight educationRane has always been about education, not marketing. Twice a year and with no – or at least, not enough – fanfare, Rane owner, Dennis Bohn, updates the Pro Audio Reference on Rane’s website. If you don’t know it, the PAR is an audio dictionary and then some. It’s August first today, so new updates are published. February first is the other release date for new audio items. Here are a few new things:

Inchindown – where the world’s longest reverberant echo is produced. Seventy (yes, 70) to 17 seconds, depending on your soprano sax range.

HAL Install in Divisible 300 Student Classroom at PNWU

Consultants at Sparling in Seattle designed a HAL1 system into a Pacific Northwest University lecture hall. Delta AV in Gresham, OR, are doing the installation. Two classrooms can be combined. Each room requires 75 push-to-talk mics for students – one at every other desk. The 150 student mics mute locally, and a variety of teachers’ mics and laptop RAD feeds tackle the instructor audio.PNWU Room Combine

Twenty-two AM2 gain-sharing automixers offer the ultimate solution. Continue reading

Georgia HAL Install – Moving the DR & RAD Locations Around

Or Hadash SanctuaryAri Newman at Shade Tree AV in Atlanta, Georgia, installed a HAL System in the Congregation Or Hadash in Sandy Springs, GA. Architectural firm BLDGS brought Shade Tree AV into the project to design a system that complemented the venue’s contemporary design.
The client wanted an audio system that could accommodate many different use scenarios, and the preset capabilities in HAL were the perfect choice. Continue reading

Using Fiber Media Converters with HAL1x’s Expansion Bus

TP-Link MC200CM

To exceed 100 meters (300 feet) distances between daisy-chained (yes, daisy-chained) EXP devices, you need an unmanaged, Gigabit Media Converter – either single-mode or multimode. The data pulsing through Rane’s Expansion Bus is not IP (Internet Protocol) and contains no MAC Addresses. Thus, you cannot connect it to an Ethernet network in any way. No Ethernet switches allowed. You must have a dedicated connection from the HAL1x to all subsequent EXP devices – up to 32 EXPs maximum.

Here is a very simple and inexpensive multimode fiber media converter we found on Amazon. The maker is TP-Link. Model number MC200CM. You need two of these – one at each end, of course. Plus the cable. We bought the blue cable, although, we’ve heard that the green cable sounds better? You’ll have to judge for yourself. Often terminating the cable is the biggest challenge – a favorite task for IT folks.

We’ve also successfully tested the Startech MCMGBSC055 which works great.

We do NOT recommend the Trend Net TFC-1000MGA – it does not work with our bus. This is where the “unmanaged” requirement fits in. If the device tries to inspect “Ethernet” packets to, for example, keep track of MAC Addresses that come and go, this is not compatible with Rane’s Expansion Bus. Our bus contains no MAC Addresses and no IP Addresses, nothing. Some but not all Managed converters allow you to turn off such packet inspections. If you’re working with IT networking folks, make this unmanaged requirement clear to them to avoid speed bumps on the Expansion Bus.

 

Know HAL #2: Plug it in, it works! (Remember analog audio?)

Remember when you could plug in a live audio cable and immediately you’d hear sound? This was before you needed an IP Address, software, a mouse or (gasp!) the correct firmware in all your devices before you could hear music. We do.

HAL's DR & RAD devices - just like analog. Yet unlike any digital audio device you know.

Rack Mounting Rane DR and RAD Devices

Often, Rane’s Decora Remote controls for HAL (e.g., DR1, DR2 or DR3 remotes and many RAD models) need to be placed in the rack room.

To mount them, get a hold of Lowell’s 19″ Punched Rack Panels – specifically, get the D9P-ID-3 model. This is a 3U panel that has nine holes for Decora devices.

NOTE: the D8P-ID-3 model does not work for any of Rane’s two-gang (or more) models. The spacing between the eight holes is not correct. Get the nine-position model.

The 9 position version offers the proper spacing for 2-gang or more DRs and RADs.

The nine- position version provides the proper spacing for 2-gang or more DRs and RADs.

To fill in the empty and unused holes, Lowell offers the DBB-4 pack of four blanks.
