Random Entropy – Factory Testing HAL

Here’s a HAL test rig. It’s been running 24/7 for 2.5 years now. Every 10 minutes or so, it changes a room combine wall and physically adjusts a DR3 remote using a stepper motor.

It’s a single HAL1 with 34 RADs in 4 EXP1s. Audio has been running for years, we’ve even been clipping several of the RADs just for yucks. They’re fine by the way. The sound of the clipping is not horrendous to listen to thanks to modern converters behaving nicely and careful analog input stage design. Remember how bad converters from the early 1990s sounded? Modern converters in the HAL products have DSP and limiting on the input to help thwart poor gain structure.

Other than updating this test rig with the latest Halogen software and firmware, we’ll keep this running. Also remember that all HALs automatically update the firmware in any connected device. And since it only takes about 10 seconds, hot-swapping portable applications are supported by RAD, DR, AM1 & AM2 auto mixers, and the Pager1. Think portable AV carts in education and corporate applications, or padded rack bags when the announcers and cheerleaders need to set up an AM1 auto mixer for the high school basketball game.
