Each channel is equipped with 18,800 μF of capacitance to deliver powerful, clear sound. Additionally, Schottky barrier diodes are incorporated to suppress rectification noise, providing a cleaner, more stable power supply for enhanced performance across all front end sections.
Stereo, Bi-amp, and BTL Modes Allow a Variety of Settings
The AP-507 is a versatile stereo amplifier that adapts seamlessly to your audio setup. It can be paired in bi-amp mode to independently drive the woofer and tweeter, or configured in BTL mode to deliver a powerful 350 watts into 8 ohms. This flexibility allows you to create an optimal system tailored to your specific speaker configuration, ensuring exceptional performance and sound quality.
Ideal for Enhancing Speaker Drive and Sound Quality in AV Surround Systems
With its compact design and impressive output power, the AP-507 is the perfect choice as a dedicated power amplifier for multichannel AV surround systems. The control terminal (Trigger In/Through) enables seamless synchronization, allowing you to power multiple AP-507 units on or off simultaneously via an AV preamp/amplifier with trigger output capability.
Beautiful and Rigid – Full Metal Chassis with Letter Size Footprint
The AP-507 features a highly rigid chassis, crafted with aluminum front, top, and side panels encasing a solid steel frame. This robust design, combined with heavy internal components, minimizes vibration to ensure stable, high-quality performance. Its compact, letter-size footprint seamlessly complements modern interiors and can easily fit on a desk. Even when used in pairs for bi-amp or BTL mode, the AP-507’s space-saving design preserves a clean and unobstructed listening environment.
Mechanical Design That Prioritizes Sound Quality
To enhance sound openness and natural sound signature, the AP-507’s 2.8mm aluminum top panel is semi-floating, sitting in place without screws, secured by slots in the side panels. This design, paired with TEAC’s proprietary Stress-Less Isolation Feet which feature a clearance between the bottom panel and the foot delivers a rich, natural sound signature.
The AP-507 is a high-performance, premium amplifier in a compact form, meticulously engineered for efficient heat dissipation without the need for exhaust fans, ensuring a quiet and immersive listening experience.
Dual Pointer VU Meters That Give You the Pulse of the Music
The AP-507’s dual VU meters add a visual dimension to your music experience. With four adjustable brightness levels (bright, medium, dark, and off), you can set the display to match your ambiance. For added dynamism, increase the meter sensitivity by +20 dB to enhance needle movement, or turn off the VU meters as desired.
