## Description

High performance in a compact design – The Audison SR amplifiers are equipped with a stable output level of 2 °C with ADC (Audison D-Class) technology for high audio performance and the integrated USS simulator (Universal Speakers Simulator), SR amplifiers are ideal for upgrading existing OEM radios. In addition, the amplifiers have an elegant and functional design with rounded corners to reduce space and facilitate installation. Versatile top-panel filter options, accessible even with installed amplifiers, complete the complete equipment. The Audison SR 4.500 is a 4-channel power amplifier with compact dimensions. Data Audison SR 4,500 power under 4/2 ohm 4 x 130/220 watts (2 x 450 watts bridged at 4 ohms) - Bandwidth 10 - 35000 Hz. - S/N ratio: 105 dBA - Input voltage: DC 6.5-17V. - High level input with USS module. - 2 x RCA inputs. - 1 x RCA output (full row). - Front filter: Full or HP/LP 50-3200Hz 12dB/Oct - Rear filter: Full or HP/LP 50-3200Hz 12dB/Oct - Bass amplification 0-12dB (channel B).

Review: The Audison SR 4.500 is a compact, efficient 4-channel class-D amplifier that punches well above its size. With 130 W × 4 at 4 Ω (and 220 W × 4 at 2 Ω), it offers clean power and tuning flexibility in a small footprint. The passive cooling design kept it quiet and reliable, even under load. Input flexibility (RCA + speaker-level) and features like ART and USS make it easy to integrate with both factory and aftermarket systems. In listening tests, it stayed clean to high volumes, handled dynamics well, and offered precise control through its built-in crossovers. It’s not a heavyweight sub amp, but for driving speakers, it’s a strong performer. Great choice for serious car audio builds without going overboard.”
