Yet, it would be foolish to ignore the implementation of modern-day capabilities, such as an informative backlit display, delicate LED illumination and remote control functionality. And just like the original, the overall appearance is unmistakably QUAD, albeit now with a premium machined and an odised front panel and all-metal chassis.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch2\u003eFunction\u003c\/h2\u003e\n\u003cp\u003eThe new QUAD 33 is supported by digital microprocessor control but is otherwise faithful to a classic analogue design. The 33 feeds the loudspeakers via the power amplifier using dedicated stereo pre-outputs, with an RCA line-level and balanced XLR pre-out option. For additional versatility and functionality, there’s also an AUX output.\u003cbr\u003e\u003cbr\u003eNow equipped with fully balanced XLR inputs and outputs, the 33 is set apart from other preamplifiers and even its forefather model. \u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThe brand new phono stage is Moving Magnet and Moving Coil compatible with the ability to simply switch between the two options – no mods or board upgrades necessary. With a gain of 46dB for the MM and 63.5dB for the MC, the input stage uses ultra-low noise audio op-amps. This ultra-low noise performance is combined with high slew rates and very low distortion specifications. The RIAA processing circuit has its own dual Bipolar\/JFET Audio Operational Amplifier. The JFET portion of the input stage enables high slew rates to keep distortion low, even when large output swings are required.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eControls\u003c\/h2\u003e\n\u003cp\u003eThe controls are comprehensive but simple. Again, this echoes the original design concept. Logically grouped to facilitate selection and control of the programme, a backlit LCD screen relays settings, adjustments and values. The same backlighting principle is applied to each of the push buttons, further enhancing the intuitive design with a visual indication of input selection and mode. Illumination settings for buttons and the LCD screen allow for brightness adjustment, contrast adjustment, and a simple on\/off setting to suit the user’s preference.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThe master volume control is a fully analogue, precision motorised ALPS potentiometer offering long-life and low-noise performance. The volume control is not only tactile and precise; its motorised operation will automatically rotate when adjustments are made via the remote control. A further row of three endless rotary encoders offer intuitive and immediate control over the QUAD-specific fine-tuning settings.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe original QUAD 33, as with many previous and subsequent QUAD preamplifier components, offered filters considered essential for ‘modern good quality speakers’ (as was stated at that time). Such controls are no longer required; therefore, in applying modern-day logic and suitability to today's technology, the new QUAD 33 presents bass adjustment, tilt control and balance control to allow tuning to a fine degree without intruding unnecessarily into the harmonic range essential for realistic reproduction.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003ePerformance\u003c\/h2\u003e\n\u003cp\u003eNo one knows more about the QUAD 33 than the immensely experienced QUAD service department – still based at QUAD HQ in Huntingdon, Cambridgeshire, England. Upon initiating this project of passion, it was determined that the new 33 and 303 combination will only see the light of day if the performance stands true and improves on the original. in over to 50 years since the release of the original 33 and 303, innovations and developments have been exponential, but only some have been employed and each with good reason. Each stage of the development and every innovation was subject to thorough testing and complete agreement with the QUAD technical design AND service team.\u003c\/p\u003e\n\u003ch2 class=\"title inline-richtext h1 scroll-trigger animate--slide-in\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"product-specifications-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eQUAD 33\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGeneral Description\u003c\/td\u003e\n\u003ctd\u003ePre Amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign Philosophy and Core Technology\u003c\/td\u003e\n\u003ctd\u003eIlluminated LCD screen\u003cbr\u003eDedicated High Performance Low Noise MM\/MC Phono stage\u003cbr\u003eClassic QUAD 'Tilt' adjustment\u003cbr\u003eClassic QUAD \/ Tone Controls\u003cbr\u003eDedicated Current-Feedback Headphone Amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e3 x RCA, 1 x Balanced XLR (pair), 1 x Phono (MM\/MC switchable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003e1 x RCA (AUX), 1 x XLR, 1 x RCA (Pre Out), 1 x Headphone, 2 x 12V Trigger Out\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePre Amplifier Section\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e0dB (Line \/ XLR)\u003cbr\u003e+46dB (Phono MM)\u003cbr\u003e+63.5dB (Phono MC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity (Vout=695mV)\u003c\/td\u003e\n\u003ctd\u003e695mV (Line \/ XLR)\u003cbr\u003e3.2mV (Phono MM)\u003cbr\u003e460uV (Phono MC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e10k (Line \/ XLR)\u003cbr\u003e47k\/100pF (Phono MM)\u003cbr\u003e100R\/1.7nF (Phono MC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Harmonic Distortion (THD)\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;0.0005% (1kHz, Line\/XLR)\u003cbr\u003e\u0026lt;0.002% (1kHz, Phono MM \/ MC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e20Hz - 20kHz (+\/-0.2dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise ratio (S\/N)\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 108dB (A-weighted, Line\/XLR)\u003cbr\u003e\u0026gt; 82dB (A-weighted, Phono MM)\u003cbr\u003e\u0026gt; 74dB (A-weighted, Phono MC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd\u003e120 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeadphone Amplifier\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Harmonic Distortion (THD)\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.01% (1kHz, 50mW)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd\u003e2.35 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad Impedance\u003c\/td\u003e\n\u003ctd\u003e20 - 600 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGeneral\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandby Power Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;0.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet weight\u003c\/td\u003e\n\u003ctd\u003e4kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross weight\u003c\/td\u003e\n\u003ctd\u003e4.96kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (mm) (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e258 x 165 x 82.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarton Size (mm) (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e330 x 257 x 192\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eClassic QUAD Grey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower requirements (depending on region)\u003c\/td\u003e\n\u003ctd\u003e220 - 240V - 50 \/ 60Hz\u003cbr\u003e100 - 120V - 50 \/ 60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard accessories\u003c\/td\u003e\n\u003ctd\u003ePower Cord, Remote Control, User Manual.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Quad","offers":[{"title":"Default Title","offer_id":56215610687874,"sku":null,"price":1199.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/6652\/0962\/files\/32621_QUAD33.jpg?v=1768427817","url":"https:\/\/premiumhomeaudio.co.uk\/products\/quad-33","provider":"Premium Home Audio","version":"1.0","type":"link"}
