Does your DSP troubleshoot the cable installation?

Close up of electrician holding cable spoolHere’s a video showing how the Hardware Workspace in Rane’s Halogen software shows you exactly where bad cables are located. Both the HAL hardware and the Halogen software point you toward the exact problem. And you thought software couldn’t fix two cables that were swapped by the folks who pulled the cable for you…

Why Rane’s HAL System RADs & DRs Require Shielded CAT 5e Cables

Shielded CAT5e or better cable for all RAD and DR devices is required solely to satisfy the high-frequency emissions and susceptibility requirements of government (FCC) and commission-based (CE) regulatory agencies. If you use unshielded cable at an installation, you are improperly installing these products, and violating the approved use restrictions in the US and CE countries. Shielded RJ-45 connector

Video Introduction to the 512×512 Expansion Bus for the HAL1x

HAL1x Expansion Bus - daisy-chain up to 32 EXP devices, in any combination.

HAL1x Expansion Bus – daisy-chain up to 32 EXP devices, in any combination.

I know, you were sad that you missed my PowerPoint presentation at Rane’s InfoComm Booth in Orlando a few weeks ago because you had to golf. Or was it Disney World, or drinks with your industry pals? Or was it because your boss sent those other co-workers from the Sydney office?

Either way, don’t fret. I recorded the PowerPoint presentation without the convention center background noise. Continue reading

Need One Cable Through Multiple Conference Rooms with an AEC Mic Mixer Under Each Table? We’ve Got That.

Easy Audio ConferencingOver and over again, customers interested in Rane’s EXP7x Acoustic Echo Canceller (AEC) for the HAL1x asked for this solution. Their problem is, there’s no way – conduit or otherwise – to get the ten mics and two lines in each of several conference rooms to an AEC and the interconnect for VoIP, video codecs (remember those?), control systems, et cetera. Enter the HAL1x approach below. Continue reading

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.
