ToneWinner AD-5100PA+ - 5-Channel Power Amplifier

ToneWinner AD-5100PA+ - 5-Channel Power Amplifier
The ToneWinner AD-5100PA+ is a five-channel power amplifier designed to expand an AV processor, receiver, or multichannel preamplifier with dedicated amplification. Delivering up to 100 watts per channel into 8 Ohms or 140 watts per channel into 4 Ohms, it is well suited for powering surround, height, or ceiling speakers in an immersive home theater system.
Its Hi-Fi amplifier circuitry uses differential input, differential amplification, and temperature compensation to support dynamic output, responsive signal transmission, and stable operation. Five independent front-panel signal indicators illuminate according to channel activity, with brightness that changes in response to the output signal level.
The AD-5100PA+ features an aluminum-alloy brushed front panel, gold-plated speaker binding posts, and an intelligent air-cooling system for efficient heat management. Five RCA inputs provide straightforward integration with compatible processors and preamplifiers, while a rear-panel trigger input allows coordinated power control with other home theater components.
