Halogen Install Hiccup

We’ve had a few customer calls where attempting to install Halogen was halted by Microsoft Windows installer error 2343.

Officially it is Error 2343: Specified path is empty during installation.

CanIn simple terms, this means a location where files must be written to and read from is not available. Either the destination is protected, or just does not exist. Maybe an external or network drive is unavailable.

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…

Managing Device IP Addresses with Halogen’s Web Controls

HAL-controlled Lemonade Stand

HAL-controlled Lemonade Stand

If you’re wondering how to effectively set up control devices and the HAL’s IP Addresses when using Halogen’s Web Controls, start here.

The controls devices such as tablets, iPads, smart phones, desktop or laptop computers are the easy part. Log them on to the WiFi (or wired) network, and be sure they are set to receive a DHCP-served IP Address (obtained automatically). This is typically the default in many gadgets these days.

HAL can use static (specified), dynamic (DHCP/obtained automatically) and/or a link-local IP address to serve the custom web pages you can create in Halogen software to the above devices.

Which IP Address to use in the HAL is often a function of the DHCP server’s capability or often the ability of the IT gal setting up the DHCP server. Continue reading

HAL1x Latency Details

Ah, the classic “Latency” question. How much time does it take audio signals to travel from a given input to a given output? Keep in mind that, generally, latency only really matters when a reinforced acoustic source also exits a nearby loudspeaker. This got quite long. But it’s complete…

 

HAL4 latency is 2.2 milliseconds. See the HAL System Data All Specifications, page 50.
HAL3s is 2.39 milliseconds – analog input to analog output, see page 49.
HAL2 is 2.39 milliseconds – analog input to analog output, see page 46.

 

The rest of this discussion is about Latency in the HAL1x and its various Expansion (EXP) and RAD devices:

 

In the HAL System Data, page 6 there is a Latency drawing (below) that shows the different latencies depending on the physical path the audio takes, input to output (almost always through the DSP Core in the HAL1x).
HAL1x, EXP & RAD Transport and Conversion Latency

HAL1x, EXP & RAD Transport, and Conversion Latency

Example #1:  HAL1x analog input (through the DSP Core) out to the HAL1x analog output is one path:

Auto Select Audio in the Priority Selector in Halogen’s Zone Processor

Here is how to program Halogen’s Priority Selector – found in the Zone Processor block – to automatically override a background music (or any other audio) simply by hitting play on another audio source. In this example, we use an iTunes song as background music, then we’ll hit “play” on an iPod music source to automatically override the iTunes source.

Check it out. What else do you want to learn how to do in Halogen? Post it in the Comments, below.

Halogen Tutorial Video: Selecting Stereo Sources in a HAL3 Using a DR3 Remote

You can use a DR3 Remote to select one of several stereo inputs. Here’s a video showing how to set up Halogen to do this for two stereo input sources.

This Halogen tutorial video shows how to link pairs of stereo zones together. Specifically, it does the stereo linking of Selectors and Levels within the Zone Processor DSP block in Halogen. This allows one DR3 Remote to select one (of two) stereo zones. It also shows how to link the left and right output volume controls together for stereo volume control.

Here’s a second video tutorial, shows how to mix two stereo input sources in a single DR3 Remote.

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

De-embed Audio from an HDMI or SDI Stream into HAL

Often, the audio sources feeding HAL System inputs originate inside an HDMI stream from a video server or Blu-ray player. There are a few products that remove, extract, split or de-embed the HDMI audio so it can feed a HAL, RAD or EXP input. Typically, these devices include an HDMI output that passes the video content onto a display, and the audio is left in the HDMI output stream in case the display also wants to output the audio.

Take a deep breath, and keep repeating: "Us audio folks love HDMI..."

Halogen Tutorial Video: Programming DR Remotes: Selecting Sources and Adjusting Volume in Many Independent Zones

Rane’s DR3 remote and its siblings, the DR2 & DR1, are consistently praised by contractors and consultants as the most intuitive and easy-to-understand control devices – especially when you have end users who need something simple.

Rane DR3, DR2 & DR1 remotes

At their cost-effective price point, these Digital Remotes, or “DRs,” are the perfect solution to augment one of the four HAL audio DSP brains.

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
