Designed to bring out the best in any speaker pair, the AD 2500 PRO features an oversized 1200-watt toroidal power transformer. This unit provides high power while maintaining inaudible noise levels. It is complemented by eight 10,000 μF capacitors for a total continuous capacity of over 80,000 μF. This setup gives the Tonewinner AD 2500 PRO exceptional dynamic capabilities and extreme responsiveness during transients. A differential circuit further improves dynamic range and reduces power supply noise and ripple.
Thanks to its isolated toroidal transformer and eight capacitors, the Tonewinner AD 2500 PRO offers excellent current delivery to handle musical or cinematic demands with balance and responsiveness.
Tonewinner AD 2500 PRO: High Power Output
The Tonewinner AD 2500 PRO is generously overbuilt to ensure it never reaches its limits. Its output stage includes eight pairs of high-power NJW0281G and NJW0302G transistors from Onsemi, chosen for their extended frequency response and high transparency, helping to reproduce even the finest sonic details. This design allows the amplifier to deliver a strong 2 x 500 W into 8 ohms in stereo mode. It operates in Class AB, striking a perfect balance between power, warmth, and natural sound.
With its 8 transistors, the Tonewinner AD 2500 PRO can efficiently power any bookshelf or floorstanding speakers at 2 x 500 W under 8 ohms.
Tonewinner AD 2500 PRO: Protection Systems
The amplifier is equipped with multiple protection systems to safeguard your speakers and other equipment. It includes protections against overvoltage, overheating, overload, overcurrent, and short circuits. This makes it safe to use at full power without risk of damage.
Thanks to these protections, the Tonewinner AD 2500 PRO can operate safely at its full rated output.
Tonewinner AD 2500 PRO: VU Meter
Built with a robust solid aluminum chassis, the amplifier forms an effective barrier against electromagnetic interference and mechanical noise. Large side-mounted heatsinks provide entirely passive cooling. The front panel also features a beautiful needle-style VU meter that displays output power in real time.
