Nortek Companies Embrace Digi5 Home-Grown Cat5 Audio Technology

A new Cat5-based audio hopes to become an industry standard. The technology, Digi5, is a product of five companies within Nortek’s Linear Home Technology Group: Elan (and sub-brand Aton), Linear, Niles, SpeakerCraft and Xantech. .

Digi5 is not a product, but a platform. Each Linear company is developing its own products based on the technology, and will tap its own channels to bring product to market. All products across brands, however, will be interoperable.

There are three basic product formats: a rack master hub, source input plate and three types of keypads.

The big difference between Digi5 and some of the other Cat5 technologies is the digital architecture of Digi5.

Digi5 offers more power—30 watts per channel RMS at 8 Ohms—than conventional keypad amplifiers for two reasons, says the group.

  1. Digi5 uses digital amps, which boast 85% efficiency, as opposed to Class A/B analog amps that are on average only 45 percent efficient, and
  2. Digi5 uses four wires for power and ground to achieve more power than either analog or digital amplified keypad systems that only use two wires for power and ground.

When installed on an equal length of Cat5, Digi5 provides nearly four times the power of a conventional Class A/B product with more total SPL, tighter sounding bass and more headroom before clipping,” argues the company..

The group plans to license Digi5 to third parties to try to make the technology the dominant platform for Cat5 multiroom audio.
