2. Broadcast Supply Worldwide (BSW)
Establishment date: 1972
Country: United States
Website: https://bswusa.com/
Introduction:
While Unit Electronics excels at serving diverse needs, Broadcast Supply Worldwide has carved out a niche in high-stakes audio: broadcast and live events. For over 50 years, they've been the quiet backbone of radio stations, TV studios, and concert venues. Walk into any of these spaces, and chances are their audio amplifiers are keeping the sound crisp. They know that in live settings, a single glitch can derail a show—so their amplifiers are built to handle sudden volume spikes, dusty backstage corners, and the chaos of live production. New to the field? Their sales reps will walk you through specs like “signal-to-noise ratio” in plain English, no jargon required.
Advantages:
-
Broadcast Expertise: Tailored solutions for RF and audio broadcasting.
-
Custom Assembly: Bespoke amplifier configurations and rack builds.

3. Texas Instruments (TI)
Establishment date: 1930
Country: United States
Website: https://www.ti.com/
Introduction:
If BSW is the steady hand for live events, Texas Instruments is the innovator redefining what audio amplifiers can do. Their engineers don't just make amps—they ask questions like, “What if we made an amp that uses 30% less battery in your headphones?” The result? Their amplifiers are in your smartphone, your kid's tablet, and even the smart speaker on your kitchen counter. They pour millions into R&D, so last year's “top audio amplifier” is already old news—this year's model probably sounds better and uses less power.
Advantages:
-
Innovation Leader: Cutting‑edge amplifier topologies (e.g., PurePath™).
-
Design Tools: Free evaluation modules and reference designs.
-
Global Support: Broad application notes and online community.

4. NXP
Establishment date: 2006
Country: Netherlands
Website: https://www.nxp.com/
Introduction:
While TI pushes the boundaries of efficiency, NXP specializes in amplifiers that thrive in tough conditions. Born from Philips' semiconductor division, they know how to make gear that survives the rough stuff. Their audio amplifiers don't flinch in a car's hot trunk, a factory floor covered in oil, or a smart fridge that's always humming. Car brands like Ford and BMW trust them because their amplifiers can handle temperature swings from -40°F to 185°F—no distortion, no shutoffs. Even smart home devices love them: their amps integrate seamlessly with Alexa, so your voice commands don't get garbled.
Advantages:
-
Automotive‑Grade: Robust for harsh environments.
-
High Integration: Combines amplifiers with DSP and codecs.
-
Eco‑Friendly: Focus on low‑power, RoHS‑compliant devices.

5. Infineon Technologies AG
Establishment date: 1999
Country: Germany
Website: https://www.infineon.com/
Introduction:
NXP's amps survive the elements, but Infineon takes it a step further—delivering raw power without wasting energy. With roots in Siemens, they're all about power efficiency. Their audio amplifiers can push 5000 watts to stadium speakers while using less electricity than a hair dryer. That's why concert venues, sports arenas, and even solar-powered outdoor setups rely on them. They're strict about quality, too: every amp goes through 100+ tests before leaving the factory, from vibration checks to voltage spikes.
Advantages:
-
High Efficiency: Up to 95% in class‑D operation.
-
Thermal Protection: Integrated safeguards for reliability.
-
Scalable Solutions: From 2 W to 300 W modules.

FAQ
Q: Should I pick a Class D or analog amplifier for my home stereo?
A: It depends on what you care about. Class D amps are compact and efficient—great if you're short on space or want to save on electricity. But analog amps (like Class AB) often have a warmer, more natural sound that audiophiles love. Try listening to both with your favorite song—you'll probably notice a difference.
Q: Do these distributors offer discounts for schools or nonprofits?
A: Many do! Unit Electronics and BSW have special rates for educational institutions—just ask for their “nonprofit program” when you call. TI even offers free samples for student projects (perfect for engineering classes).
Q: What if I need help setting up the amplifier after buying it?
A: Most distributors, including us at Unit Electronics, offer free tech support. BSW's reps will even walk you through setup over the phone, and TI has video tutorials for their chips. No shame in asking—we've all stared at a wiring diagram and thought, “What does this even mean?”
Q: Can I get a custom amplifier built for my unique project?
A: Absolutely. Texas Instruments, NXP, and Unit Electronics all do custom designs. Just share your specs—like “needs to fit in a 3-inch box” or “must run on 9V batteries”—and their engineers will draft a solution. It takes a bit longer, but it's worth it for a perfect fit.
