ToneWinner AD-3240PA - 3-Channel Power Amplifier

ToneWinner AD-3240PA - 3-Channel Power Amplifier
The ToneWinner AD-3240PA is a three-channel power amplifier designed to provide dedicated, high-output amplification for the front soundstage of a home theater system. Delivering up to 250 watts per channel into 8 Ohms and 400 watts into 4 Ohms, it supplies the power needed for dynamic movie soundtracks, detailed music playback, and demanding loudspeaker systems.
Audiophile-grade dual-differential amplification circuits and temperature-compensation circuitry help maintain a high signal-to-noise ratio and stable performance. The amplifier supports both balanced XLR and unbalanced RCA connections, allowing it to integrate with a wide variety of surround processors and preamplifiers. Three independent signal indicators provide clear visual confirmation of channel activity.
A brushed aluminum-alloy front panel and gold-plated speaker binding posts give the AD-3240PA a durable, refined construction. Intelligent air cooling and comprehensive protection circuitry guard against excessive voltage, temperature, current, load, and short-circuit conditions. Trigger input and output connections also allow the amplifier to power on and off with compatible home theater components.
