A Vancouver musician’s direct box, “built like a tank.”

Radial Engineering is a Canadian maker of direct boxes — the small boxes that turn a guitar, bass or keyboard signal into a balanced, microphone-level feed for a mixing desk — and of other tools for stage and studio. The company’s history page says it was founded in Vancouver, British Columbia, by the musician and entrepreneur Peter Janis, and counts its work from 1996, the year its first product appeared. The private-equity firm that bought the company in 2018 described it as established in 1991, so we note both dates.

That first product was the JDI, a passive direct box. Radial says it was designed in answer to widespread frustration with low-quality DIs, was “built like a tank,” and used transformers from Jensen, the American transformer maker. Exports to the United States followed, and Radial says the JDI was widely adopted as an industry-standard DI. The company still sells it, now billed as the “World’s Finest DI For 30 Years.” Its product page names the transformer inside as a Jensen JT-DB-EPC, claims a response that is flat from 10Hz to 40kHz, and recommends the box for high-output basses, acoustic guitars with built-in preamps and digital keyboards. Because it needs no power, it also passes signal across a transformer that blocks stray DC voltage, which Radial says helps it remove the hum and buzz of ground loops.

The range grew around it. The J48, an active direct box powered by a mixing desk’s phantom power, followed in 2002, and in 2004 the cheaper ProSeries DIs, built around a transformer Radial says it developed in-house. In 2000 Radial had launched a sister company, Primacoustic, to make acoustic panels, beginning with its Broadway glass-wool line, and in 2001 it took on and expanded the Tonebone brand of effect pedals, the company says.

Reamp, Jensen and a run of acquisitions.

Radial grew partly by buying the names behind its products. The best known is Reamp. The recording engineer John Cuniberti devised the Reamp box, which sends a recorded guitar track back out to an amplifier so it can be re-recorded; Wikipedia says he announced the sale of the Reamp patent, trademark and business assets to Radial in late 2010, and Radial dates the acquisition to 2011. Radial says it secured the “Reamp” trademark from the US Patent and Trademark Office in 2013 and went on to make the Reamp Station, Reamp HP and EXTC-Stereo, among others.

In 2014 Radial bought Jensen Transformers, which it describes as one of its biggest suppliers, and says it then invested in new machinery for Jensen’s OEM business to secure a steady supply of transformers for its own products. Through the 2010s the range spread to switchers, preamps, line isolators, audio carried over Cat5 cable, and Dante- and Bluetooth-equipped devices. Radial says its JX44 V2 switcher and PZ-Pro acoustic preamp were nominated for TEC Awards, and that its Catapult Rack was nominated in the awards’ Production Essentials category in 2025.

Its client list is long. Radial’s history names the Rolling Stones, Sting, U2, Dua Lipa, Olivia Rodrigo, AC/DC, Maroon 5, Jelly Roll, Jason Aldean and Metallica among the acts that have used its gear, and an earlier passage adds Rush; we give these as the company’s claims.

Microphone accessories and signal tools.

The seven brands in this guide make the small tools that sit between a voice or instrument and the mixing desk. Two treat the sound before it reaches the microphone. Stedman, of Richland, Michigan, has made music products since 1992, chiefly Proscreen pop filters, and says it assembles them at its own Michigan factory. Kaotica, founded by Konrad Zukowski, makes the Eyeball, a ball-shaped acoustic shield that fits around a microphone, and says it launched in New York in 2014 and manufactures in the United States.

Rycote makes windshields and shock mounts. Its own timeline says the sound recordist John Gozzard founded it in 1969; Vitec, the British group now called Videndum, bought it in 2018, and in 2023 it moved from Stroud, Gloucestershire, to Ashby-de-la-Zouch, Leicestershire, saying its manufacturing has stayed in Britain.

Two make inline preamps that add clean gain to quiet microphones. Triton Audio was started in the Netherlands in 2006 by Erwin Erkamp and Peter-Paul Wijte, launched its FetHead in 2008, and says its products are assembled there. Cloud Microphones, of Tucson, makes the Cloudlifter and says its products are made in Arizona.

The last two carry the signal to the desk. Radial Engineering, founded in Vancouver by Peter Janis, introduced its JDI direct box in 1996; Radial says Janis sold it to Regimen Equity Partners in 2018, and it is now based in Port Coquitlam, British Columbia. Whirlwind, founded in Rochester, New York, in 1975 by Michael Laiacona, makes snakes, cables and DI boxes, and says its Medusa snakes are still hand-made in Rochester.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

True To Your Music.

Janis sold the company in 2018. The Canadian private-equity firm Regimen Equity Partners announced in February that year that it had acquired Radial Engineering Ltd. “in partnership with Mike Belitz,” a music-industry executive who was to become president and chief executive; Janis was retiring “after nearly 42 years in the music industry,” the announcement said. Regimen, which says it runs a 30-year fund and aims to hold businesses for more than 20 years, still lists Radial in its portfolio as an investment made in 2018. It says Radial’s products are sold through dealers and distributors in nearly 60 countries. Its 2018 announcement also counted Hafler and Dynaco among Radial’s brands; its current portfolio page lists Radial, Primacoustic, Tonebone, Reamp, Power, Iso-Max and Jensen Transformers.

Radial’s headquarters is in Port Coquitlam, east of Vancouver. In 2019 it opened a US warehouse in Loveland, Colorado, and in February 2021 it moved, with Primacoustic, into a larger purpose-built building a few minutes from its old site. Belitz, signing as CEO, said the move would nearly double its “in-house production and warehouse areas” and house a recording studio for testing products. Radial does not say on its product pages where each product is made, and we could not establish which are built in Canada.

The identity is spare. The company website pairs black and white with a bright red, and a January 2025 post sets out the line “True To Your Music”; in 2026 Radial began marking its 30th anniversary with a campaign called TTYM30. We found no published brand guide or official colour code.

For a design guide, Radial Engineering shows how a tool brand can be built on one dependable product. Compare its sister brand Primacoustic and Neutrik, another maker of the hardware behind live sound. For this guide we use stage black, signal red and steel grey with a condensed sans, an unofficial interpretation; no product or logo is reproduced.
