QUAD 33 analogue pre-amplifier
About the QUAD 33 analogue pre-amplifier
Product Description
Function
The 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.
Now equipped with fully balanced XLR inputs and outputs, the 33 is set apart from other preamplifiers and even its forefather model. The 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.
Controls
The 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.
The 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.
The 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.
Performance
No 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.
