Fully Balanced Circuitry The AP-507 is engineered for pristine audio clarity, utilizing fully balanced transmission across all stages of its front-end buffer amplifier and power amplifier sections. This design effectively eliminates common-mode noise, ensuring ultra-low noise signal transmission and an exceptional signal-to-noise ratio for an uncompromised listening experience. Circuit Design Focused on Sound Quality The dual-mono buffer amplifier, a critical component for superior sound quality, has been meticulously refined for the AP-507. By re-evaluating and enhancing its parts and circuitry, TEAC has achieved even greater audio performance than previous models. Both the RCA and XLR input circuits feature the premium Muses 8820E operational amplifier, ensuring high-fidelity sound reproduction. Additionally, the XLR input section is designed without coupling capacitors, eliminating transmission loss and preserving musical detail with unparalleled accuracy and clarity. Buffer Amplifier Power Section with Large Toroidal Core Transformer The AP-507 features a robust power section for its buffer amplifier, anchored by a large toroidal core transformer. Its dual-mono power rectifier design, with independent left and right channels, ensures optimal channel separation and eliminates interchannel crosstalk. 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. Shown with TANNOY SGM 10 in BI-AMP or BTL configuration. 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.
