Allen Avionics

What Allen Avionics does

Allen Avionics, Inc. is a US-based manufacturer of precision passive electronic components, founded in 1960 and currently operating as a division of Star Hydraulics within the Alkon corporate family. Headquartered and manufactured at 2727 Clinton Street, River Grove, Illinois (near Chicago's O'Hare airport), the company holds ISO 9001:2015 certification (achieved 2018 via NSF) and employs between 11 and 50 people. Its product portfolio is organized into four lines: noise and hum elimination products (video isolation transformers, ground loop eliminators, audio ground loop isolators, HD/3G-SDI hum eliminators); custom LC filters (lowpass, highpass, band pass/reject, high-power, and diplexer filters); active and passive delay products (video and general-purpose delay lines, custom delay circuits, and audio/video delay systems); and offset marking equipment (machines, type, inks, and accessories).

The company's core technology is analog signal conditioning — passive LC filter topologies, transformer-based galvanic isolation, and electromagnetic delay structures — engineered for broadcast-quality audio/video applications and electronics OEM integration. Notable specifications include bandwidths up to 6 GHz (ISO-6G-SDI), >60dB ground loop isolation, 2kV flash-tested isolation, and SMPTE 259m/292m/424m compliance. The custom filter and delay line design service allows tailoring to OEM specifications.

Commercially, Allen Avionics operates a hybrid direct and channel model: a quote-based direct storefront on its website (accepting major credit cards) supplemented by a global distributor network spanning the US, UK, France, China, and India — including specialty partners such as Canford Audio, Eurocom Broadcast, Miami Video, Newark Element 14, India Electronics Pte Ltd., and B&H Photo. Revenue is generated through one-time hardware sales across three primary verticals: broadcast and professional A/V, electronics OEMs requiring precision filters and delay lines, and industrial manufacturers using offset marking equipment. Pricing is opaque (quote-based for most products) with modest volume discounts on the marking line (10–40% at $100–$750+ order thresholds). Marketing relies on the company website, downloadable datasheets and whitepapers, social media, and trade show participation.
