Description
High-Power 4-Channel Class-AB Car Amplifier
Experience powerful, dynamic sound with the IMPULSE AREF 3. Designed for demanding car-audio systems, this four-channel amplifier delivers strong output with low distortion, excellent channel control and flexible installation options.
Its robust internal construction features dual toroidal power transformers, Sanken complementary audio-output transistors and four large 10,000 µF power capacitors. This substantial power-supply architecture provides the current reserve needed for controlled bass, clear vocals and energetic musical performance.
The AREF 3 can operate as a conventional four-channel amplifier or in bridged mode to drive more demanding speakers and subwoofers. Independent gain controls allow accurate level matching, while gold-plated terminals provide secure, low-resistance power and speaker connections.
A transparent display cover showcases the amplifier’s symmetrical internal architecture, combining premium appearance with serious car-audio performance.
