TEAC AP-507 Stereo Power Amplifier - High-Power Balanced Design

The TEAC AP‑507 is a compact stereo power amplifier in the Reference 500 series that delivers impressive power and clarity. At its heart is a custom‑tuned Hypex NCOREx Class‑D module paired with TEAC’s dual‑mono buffer amplifier, producing 170 W per channel into 4 Ω or an astonishing 350 W in bridged (BTL) mode. Choose between stereo, bi‑amp and bridged configurations to tailor the amplifier to your speakers and system.

Fully balanced circuitry with a dual‑mono power supply, 18,800 µF capacitors per channel and a toroidal transformer provide high current with low distortion. A semi‑floating top panel and Stress‑Less isolation feet minimise vibrations, while dual analog VU meters let you monitor power output in real time. Balanced XLR and unbalanced RCA inputs, robust speaker posts and 12 V trigger connectivity make the AP‑507 a versatile powerhouse in a stylish, letter‑size chassis.

Product Q&A:

Q: What class of amplifier is the AP‑507?

A: It uses a custom‑tuned Hypex NCOREx Class‑D module paired with TEAC’s own dual‑mono buffer amplifier for high efficiency and low distortion.

Q: How much power does it deliver?

A: The AP‑507 provides 170 W per channel into 4 Ω (95 W at 8 Ω) and up to 350 W into 8 Ω when bridged (BTL).

Q: What modes of operation are available?

A: It offers stereo, bi‑amp and bridged modes, letting you optimise power delivery for different speakers.

Q: How does TEAC reduce vibration?

A: A thick semi‑floating top plate and Stress‑Less isolation feet isolate the chassis from vibrations for improved sound quality.

Q: What inputs and outputs are provided?

A: Balanced XLR and unbalanced RCA inputs, robust binding posts and 12 V trigger in/out make it easy to integrate with a wide range of systems.

Q: Are there visual meters?

A: Yes, dual analog VU meters with adjustable brightness allow you to monitor output levels at a glance.
