AUDIOVALVE Conductor Pre-amplifier with remote

$21,000.00

Product Description

As for all AudioValve products, the chief himself has had a hand in CONSTRUCTOR’S PCBs. The complex designs of the circuit boards took nearly 12 months and followed strictly the design optimization for signal and live conductor paths. The complex double-sided circuit boards come per unit close to 30 dm2. In this way highly constant DC voltage as well as signals arrive straight at the valves via a few centimeters of circuit conductors and contribute to a homogeneous and balanced music reproduction.

 

 

The casing design is also revolutionary new. A blue lit three-dimensional clear acrylic plate with logo and lettering allows a view on the master board with the valves und creates a fascinating and unique atmosphere in a darkened room, without emitting a single sound.

Surely – this kind of design has its price, but we found the best just being good enough for you, which sets us once again apart from the competition, and sends a signal of what you can expect from the market. Don’t be satisfied with less.

The amplifier is separated in three components: signal component, power supply and micro-controller. Signal and power supply components come in separate casings while the controller is part of the amplifier display and handles all tasks in terms of control. Left and right channels are strictly designed as dual mono, within the power supply as well as the signal component.

 

The power supply features for the anode potential alone nearly 10,000µF/400VDC (!!!) and for the heater component 100,000µF see to the necessary DC voltage on a 30x30cm circuit board.

 

An oversized toroidal transformer with static and magnetic shielding supplies a total of 8 conductor paths, four for the production of the anode potential and four for the heat production. On the side of the power supply everything is done to be completely safe from any kind of power failures. In keeping the paths to the valves as short as possible the voltage stabilizers are located right next to amplifier paths.

They are accompanied by polypropylene condensers as “RF – blockers”. These voltages reach 8 highly constant low-resistance voltage regulators, which take the last bit of ripple out of the heater as well as the anode potential and supply an amazingly clean supply voltage, no matter how the mains power supply may be.

 

 

 

As with AudioValve’s Eklipse also with CONDUCTOR the volume is only controlled behind the first amplifier stage. Thus the first stage can fully develop its “tubal” tonal dynamic freedom and supply the output drivers via the volume control.

In this way the signals keep their unlimited authenticity, the signal to noise ratio in the CONDUCTOR concept is by far better compared with traditional volume control.

Digital volume control was for quality reasons not considered. An analog potentiometer with six sections is used, four of which control the signals and the remaining are used for potentiometer servo control, which not only store the volumes of each channel, but also update when switching to a different channel. A graphic bar on the color display informs about the potentiometer angle of rotation and/or volume setting. An awesome design – typical AudioValve.

All these are conditions for perfect sound, even though the amplifier is the most important component for music reproduction. The special problem with fully symmetric amplifiers is the fact that for the right as well as for the left channel two amplifier paths each are required for processing of positive and negative signal waves. This fact alone requires for valve amplifiers an enormous circuit complexity. But there are also a lot of stories around signal processing, some of them quite new.

As complex as we designed the power supply, as complex is the signal component. Altogether 8 valves provide the generation of the +/- phases of the right and left channels. Two of the 6922 type see to the differentiation of the input signals for the plus/minus phases of each channel, two more of the 6N6P type see to the low-resistance output of the signals to the output connectors. The amplifier paths have no “global feedback loop” and deliver the signals phase-correct to two reversible outputs. Selected, according to strict criteria developed components as well in the power supply as in the signal component, round off the musical result of CONDUCTOR. AudioValve went through the pain of having own condensers developed, all of which carry the AudioValve logo – as proof for the authenticity of our products and underscoring the special quality of CONDUCTOR.

More than 12 months the technicians were busy with design and construction of this amplifier. Again and again the circuitry was fine-tuned during sound tests to finally present a brilliant masterpiece, the CONDUCTOR – for you.

 

AudioValve also said goodbye to traditional single or dual row displays and offers a well-arranged graphic display – controlled by a micro controller – showing the equipment status at one glance.

You don’t have to click through long-winding menus before being able to read or set the desired information – no, for the CONDUCTOR the display transmits all important information at a single glance.
