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

Halogen’s Supported Character Set

Halogen software allows you to use character codes from 0 to 255 in your names and other text fields (including those that appear on DR LCD displays). The character encoding is code page 1252 (CP1252) and the following table shows the supported character set.

 

To enter any of these Unicode characters in any Halogen field from the keyboard:

  1. Press and hold down the Alt key.
  1. On the numeric keypad type 0 (zero) and then the decimal character code below.
  1. Release the Alt key.

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.

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.

New HAL System Products for InfoComm 2014

How did we improve a product by 750 times? That’s 57.5 dB better. And don’t worry, the accounting department checked and double checked our math here, so you know it’s gotta be good.Math

Here’s an informal video slide deck of three new products.

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).
