The Audiophonics AP300-S2503E is a stereo power amplifier featuring a 3e Audio PFFB amplifier module. This enables it to develop 2x250W of power under 4Ω while delivering exceptional sound quality, combining precision and dynamics. All components are assembled - in a magnificent, sturdy aluminum case with acrylic front panel - by hand in our workshop in France.
The heart of the Audiophonics AP300-S2503E is its 3E AUDIO 260-2-29A PFFB amplifier module. This amplifier is based on a meticulous Class D architecture, enabling it to develop a comfortable 2x250W of power under 4Ω. Power that goes hand in hand with sound reproduction of great precision and richness. To achieve this, the module uses an advanced feedback design (Post Filter Feedback) as well as a proprietary error correction system (PurePath™ Ultra-HD). The latter enables it to achieve an extremely low level of distortion across the entire frequency band, enhancing its sound quality.
The power supply stage of the AP300-S2503E incorporates a Mornsun LOF550-20B48 switching power supply module. This uses high-quality components to deliver a clean, stable electrical signal to the amplifier module, an essential step in ensuring transparent, accurate sound reproduction.
The Audiophonics AP300-S2503E is equipped with simple, effective connectors. Its rear panel features a single balanced XLR input. Output is via speaker terminals that accept bare cables, forks and bananas. Finally, a 3.5mm jack is also provided for the device's 5-12V trigger, enabling automatic switching on and off of the various devices in your audio system.
