Tonewinner AD-7300PA+: 7-channel Class AB power amplifier

The Tonewinner AD-7300PA+ is a 7-channel Class AB power amplifier ideal for home theater integration. Capable of delivering significant power, measured at 584W RMS for a single channel driven from 4Ω or 7x190W for 7 channels driven from 8Ω, this amplifier offers excellent dynamics and delivers low noise.

This high power level requires the integration of a complete and effective protection circuit. Therefore, Tonewinner AD-7300PA+ is equipped with protection against short circuit, overload, overheat, overvoltage and overcurrent.

To provide this power, the AD-7300PA+ uses 7 independent discrete mono amplifier modules. Each of them is equipped with 3 pairs of high-performance Onsemi NJW0281G and NJW0302G transistors. The left and right channels also benefit from a high-current configuration approaching the performance of a Class A architecture, and use side-mounted heatsinks to effectively dissipate the heat generated by such a design.

In addition, single-ended RCA input and balanced XLR input are available for each channel. Input selection is done using a switch for each channel.

Weighing in at 25kg on the scale, the Tonewinner AD-7300PA+ is a massive amplifier, clad in an aluminum chassis and two large side-mounted heatsinks. On its front panel there is an impressive blue meter with adjustable brightness.
