The **Teac AP‑507** is a reference-class stereo power amplifier from Teac’s compact 500 Series. Featuring custom‑tuned Hypex **NCOREx®** modules and dual‑mono buffer amplification, it yields exceptional dynamics and clarity in a compact, fan‑less chassis.
Details
Capable of delivering **170 W per channel into 4 Ω** (95 W into 8 Ω in stereo/bi‑amp mode) and up to **350 W in bridged mono (BTL) mode**, this amplifier excels at both music and home theatre performance. Fully balanced circuitry throughout minimizes noise, while the **semi‑floating 2.8 mm aluminum top plate** and **3‑point Stress‑Less Isolation Foot system** reduce vibration and enhance tonal purity.
The front panel features **dual pointer VU meters** with adjustable brightness and sensitivity controls. Connectivity includes **balanced XLR and unbalanced RCA inputs**, large screw-type speaker terminals, and **12 V trigger in/thru** for system integration control. A triggerable power-saving function ensures efficient standby operation.
