Originally celebrated for its reliability in both domestic and professional environments, the 303 returns with modern performance, improved power delivery, and refined circuitry—while staying true to the philosophy that made it legendary.\u003c\/p\u003e\n\u003cp\u003eThis latest iteration goes far beyond a simple component refresh. Retaining QUAD’s famous “symmetrical triples” output stage, the new 303 delivers vanishingly low distortion and exceptional stability, even under demanding conditions. With a fully complementary output stage and upgraded internal architecture, it offers greater linearity, improved reliability, and enhanced sonic performance.\u003c\/p\u003e\n\u003cp\u003eCombining heritage design with modern engineering, the QUAD 303 delivers a powerful, controlled, and musically engaging sound that honours its legacy while meeting today’s expectations.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRe-engineered version of the iconic QUAD 303 amplifier\u003c\/li\u003e\n\u003cli\u003eQUAD “symmetrical triples” output stage for ultra-low distortion\u003c\/li\u003e\n\u003cli\u003eFully complementary output stage for improved linearity and stability\u003c\/li\u003e\n\u003cli\u003eCustom low-noise 200VA toroidal transformer\u003c\/li\u003e\n\u003cli\u003eAdvanced feedback topology for thermal stability and dynamic performance\u003c\/li\u003e\n\u003cli\u003eStereo and bridged mode operation\u003c\/li\u003e\n\u003cli\u003eHigh current capability for demanding speaker loads\u003c\/li\u003e\n\u003cli\u003eClassic QUAD industrial design with modern build quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eConnections:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInputs: 1 x RCA (line), 1 x XLR (balanced)\u003c\/li\u003e\n\u003cli\u003eOutputs: Speaker terminals (stereo), 12V trigger, 12V trigger link\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTechnical Specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAmplifier type: Class AB power amplifier\u003c\/li\u003e\n\u003cli\u003ePower output (Stereo): 2 x 50W (8Ω), 2 x 70W (4Ω)\u003c\/li\u003e\n\u003cli\u003ePower output (Bridged): 140W (8Ω), 170W (4Ω)\u003c\/li\u003e\n\u003cli\u003eGain: +29dB\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20Hz – 20kHz (±0.3dB)\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion: \u0026lt;0.002% (1kHz)\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio: \u0026gt;108dB (A-weighted)\u003c\/li\u003e\n\u003cli\u003eInput impedance: 10kΩ\u003c\/li\u003e\n\u003cli\u003eInput sensitivity: 700mV (RCA), 1.5V (XLR)\u003c\/li\u003e\n\u003cli\u003eMaximum output current: 10A\u003c\/li\u003e\n\u003cli\u003eStandby power consumption: \u0026lt;0.5W\u003c\/li\u003e\n\u003cli\u003eDimensions: 325 x 176 x 120 mm (W x H x D)\u003c\/li\u003e\n\u003cli\u003eWeight: 8.4 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFinish:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eClassic QUAD Grey\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat’s Included:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQUAD 303 Power Amplifier\u003c\/li\u003e\n\u003cli\u003ePower cable\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eManufacturer packaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote: This product is available for in-store purchase and demonstration only.
