Teac AP507B Stereo Power Amplifier - Black

The Teac AP507B stereo power amplifier is a compact audio beast that blends serious power with high-end sound engineering, all wrapped up in a sleek, letter-sized design. Whether you're building out a high-performance stereo setup, bi-amping your speakers, or pushing full power in BTL mode, this amplifier is built to perform—and impress.

Pure Power, No Compromises

The Teac AP507B isn't just compact—it’s packing serious power. It cranks out 170 watts per channel into 4 ohms and can push a staggering 350 watts into 8 ohms when switched to BTL (Bridged) mode. Whether you're driving bookshelf speakers or large floorstanders, this amp has more than enough juice to make them sing.

Engineered Around Hypex NCOREx Technology

At its core, the Teac AP507B features the latest generation NCOREx power amplifier modules from Hypex, custom-tuned by TEAC. This isn't your average Class D amp. You get a wide, immersive soundstage, tight bass, and incredible clarity that brings out every nuance in your music. Think of it like giving your speakers a fresh set of lungs—they breathe better, sound clearer, and carry more emotion.

Fully Balanced for Crystal-Clear Audio

Noise? Not here. Thanks to fully balanced circuitry from input to output, the Teac AP507B keeps your signal path clean. Common-mode noise gets canceled out, leaving you with nothing but pristine, high-resolution sound. It’s all about letting the music through—untouched and unfiltered.

Flexible Enough for Any Setup

One of the coolest things about the Teac AP507B is how versatile it is. Want to bi-amp your speakers and give each driver its own channel? Easy. Prefer to go full-on BTL mode for massive power output? No problem. You can even integrate it into a surround sound setup as a dedicated power amp. It fits where you need it—and does the job better than most full-sized units.

Precision Power Delivery

Behind the scenes, the AP507B is built for audiophile-grade performance. Inside, you’ll find a dual-mono buffer amplifier powered by a large toroidal core transformer, massive 18,800 μF capacitors per channel, and noise-reducing Schottky barrier diodes. Translation? It delivers clean, consistent power with rock-solid channel separation and zero crosstalk.

Tuned for Musical Detail

TEAC went all-in on sound quality. They refined their in-house dual-mono buffer amplifier design, upgraded the parts, and used premium MUSES 8820E op-amps on both XLR and RCA inputs. Even the XLR input path is cap-free to keep signal loss at bay. It’s like giving your music a direct route with no speed bumps.

Solid Build, Silent Operation

This amp isn’t just smart on the inside—it’s smart on the outside too. With a 2.8mm thick semi-floating aluminum top plate and TEAC’s Stress-Less Isolation Feet, vibrations don’t stand a chance. There’s no fan either, which means zero noise during playback. Just music, the way it’s meant to be heard.

Designed to Look as Good as It Sounds

The full metal chassis doesn’t just keep things sturdy—it looks sharp too. Whether you place it on a shelf, a rack, or your desk, the Teac AP507B fits right in without crowding your space. It’s one of those rare audio components that blends form with function beautifully.

Visual Feedback with Dual VU Meters

Want a little flair with your fidelity? The AP507B gives you real-time VU meters—complete with adjustable brightness and sensitivity. Crank them up for visual drama or dim them down for a minimalist vibe. It’s a small touch that adds a lot of personality.

When it comes down to it, the Teac AP507B proves you don’t need a huge box to get huge sound. It’s compact, flexible, and powerful enough to anchor any serious hi-fi or AV setup. If you're ready to elevate your audio game without sacrificing space or style, this is the amplifier to beat.
