Axiom ML1

Audio extension I/O module (Attero Tech) (discontinued)

The Attero Tech Axiom ML1 provides installation-friendly and intuitive analog audio extension (via CAT-5 or greater) of analog microphone and line level sources for cost-sensitive applications such as small and medium sized retail, restaurant, education and hospitality venues. The ML1 must be paired with the Attero Tech AXP2O (sold separately) to operate. AXP20 outputs the necessary analog signal from ML1 into an AV system, mixer or other audio destination.

Key Features

  • XLR input provides connectivity for dynamic microphones with 50 dB of adjustable gain
  • ¼” connector includes a fixed attenuator pad for +4 dBu nominal input levels
  • 3.5 mm jack provides consumer (-10 dBV nominal) input level with 20 dB of adjustable gain and is summed to mono
  • Audio signal level indicator LEDs for each input provide quick feedback for proper input gain adjustments
  • Selectable sum-to-mono option for both inputs, allowing 2 ML1s or another Axiom device to be daisy-chain connected on a single bus
