Tested & Working - Digital Optical/Coaxial OutDescription:Up for sale is a rare, bench-tested Auvio HD Radio Tuner (Model 31-134). If you are looking to add high-definition radio to your vintage silver-face stack or a modern home theater setup, this is widely considered one of the best ways to do it.While most HD tuners are cheap portable units, this is a full-sized component designed for high-fidelity audio. It allows you to access HD1, HD2, and HD3 digital sub-channels that you can't get with a standard FM radio.This model is a favorite in the audio community because of its connectivity. It features:• Optical (Toslink) & Coaxial Digital Outputs: Bypass the internal DAC and run a pure digital signal directly into your high-end receiver or outboard DAC.• Standard RCA Analog Outs: For compatibility with vintage integrated amps.• Crystal Clear VFD Display: Great visibility in a dark rack.• HD Multicasting: Pulls in those "hidden" local stations with no subscription fees.Condition:• Functionality: Fully tested. It pulls signals strongly and locks onto HD sub-channels quickly.• Cosmetics: Excellent condition. The rear panel is clean (see photos) and the chassis is well-cared for.• Note: This listing is for the tuner unit only. Remote is not included, though the front panel buttons allow for full navigation/tuning, and it is compatible with many universal remote systems.
At USD80 for a 2009 Auvio 31-134 HD tuner, this strikes me as a fair ask if it's in solid working order—typical used pricing for these discontinued black units hovers around USD60-100 on enthusiast markets, depending on cosmetics and accessories. Mint examples with boxes have pushed toward the higher end recently, but untested or worn ones dip lower, so it's not a screaming bargain unless provenance is spot-on.
Before biting, verify the remote works flawlessly—these quirky beasts rely on it heavily, and replacements are scarce. Also check for HD lock on strong stations; cap issues or digital board glitches cropped up after 15 years, so test thoroughly and confirm the original power cord and manual are included to avoid headaches.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
I cannot provide a confident editorial description of Auvio based on these search results. While the results confirm that Auvio is a consumer audio brand associated with RadioShack that produces Bluetooth speakers, portable speakers, bookshelf speakers, and headphones, the search results lack essential information needed for a credible brand biography.
Specifically, the results do not establish Auvio's founding year, country of origin, founder identity, or founding circumstances. The brand appears to be a house label or product line rather than an independent manufacturer with documented heritage, but this cannot be verified from the available sources. The search results offer only scattered product references—a mini Bluetooth speaker, 2-way bookshelf speakers, in-ear headphones, and wireless speaker kits—without comprehensive category coverage or market positioning analysis.
To write an accurate editorial description suitable for a knowledgeable hi-fi audience, I would need reliable sources covering Auvio's corporate history, manufacturing philosophy, market positioning relative to competitors, and the breadth of their product portfolio. Without this foundation, any description would risk inaccuracy. I recommend consulting RadioShack's official brand documentation, industry archives, or trade publications that have covered Auvio's development and market role.
