The Audison SR 4.500 is a compact 4-channel D-Class amplifier designed to deliver strong, clean power without taking up much space.
It produces 130W x 4 at 4 ohms and 220W x 4 at 2 ohms, making it a solid choice for upgrading factory or aftermarket audio systems with more clarity, punch and control.
Built with an extruded aluminium chassis and rounded corners, the SR 4.500 is made for easier installation in tighter spaces.
Audison also uses large side heat sinks, so there is no need for internal cooling fans, helping reduce noise and dust build-up over time.
Features:
- ADC (Audison D-Class) Technology stable output stage ensuring high audio performance in a compact size.
- Extruded aluminium compact design with fan less convection cooling system.
- Built-in USS (Universal Speakers Simulator).
- Balanced high-noise rejection input speaker-In (for OEM head units) and RCA-In (for Aftermarket head units) inputs.
- ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/ disabled, with Speaker-In inputs).
- Pre-outs, also available when using Speaker-In level inputs.
- Mono operation mode (selectable), to create a sub + front three-channel system or a powerful 2-channel system.
- Bass Boost (50 Hz) adjustable to 12 dB, to increase the subwoofer punch.
- Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 3200 Hz) filters, providing the ability to build a front + rear system, a multichannel woofer + tweeter system or a powerful sub + front system.
