TEAC AP-507 – Power in a Compact Case

16.02.2025 06:09 | ~1 minute read

TEAC has introduced the compact TEAC AP-507 two-channel power amplifier, which implements the latest Hypex NCOREx Class D technology. Compared to its predecessor AP-505, the TEAC AP-507 is equipped with an updated amplifier module with higher output power and low distortion. In addition, the TEAC AP-507 amplifier supports bridge mode for use as a powerful monoblock.

The TEAC AP-507 uses a new generation NCOREx power amplifier module from TEAC, developed jointly with Hypex and operating in Class D. The TEAC AP-507 in stereo mode develops up to 70 watts per channel at an 8 ohm load and 125 watts for a 4 ohm load. When bridged, the output power increases to an impressive 230 watts at an 8 ohm load. Such characteristics are provided by a power supply based on a large toroidal transformer and a filter with capacitors with a total capacity of 18,800 μF for each channel.

The case of the new product is made of aluminum and steel with a semi-floating top panel made of 2.8 mm thick aluminum and uses a system on three anti-vibration supports Stress-Less Isolation Foot. The front panel of the TEAC AP-507 amplifier is decorated with VU meters with a four-stage dimmer for the backlight brightness. The TEAC AP-507 stereo power amplifier is expected to be available in the spring 2025 at a recommended retail price of $ 2,199 / € 1,899.
