Description

Introduced on the market in 1995, Audio Research's Reference Series has since been the ultimate exemplification of the concepts of performance, musicality and power applied to the reproduction of recorded music. Now, the Reference 6 continues the traditional commitment to the use of the most refined circuit designs in combination with the components and parts of the highest quality possible. Thus, a large number of components used - transformer, capacitor, cabling - use exclusive designs for Audio Research and Reference 6, while the use of a completely new chassis has not only improved the aesthetics of the device, but also Provide a more rigid structure to improve the evacuation of possible electrical and mechanical interferences. Now, in the audio circuit itself, we find six very high quality 6H30 vacuum valves (against the four of the previous model, the Reference 5SE) so that the background noise is even lower and the dynamic range is increased. The power supply regulated with vacuum valves (in particular the 6550WE) uses a new design in order to improve the sound quality. New printed circuit boards, new circuit topologies and a large power transformer have been added to add robustness and facilitate both the use and maintenance of the device, which is completed by a new volume control with finer adjustment steps and Superior performance. A large fluorescent display on the front panel shows all the functions of the Reference 6 as well as the volume level. Two rotary encoders handle volume control and input selection, while a five-button row controls start-up, squelch circuit, absolute phase reversal, monaural mode activation and menu system . With regard to the menu, let's point out that it allows to manage the name of the input sources, the brightness level of the function display and the configuration of the input for processor, as well as resetting the useful life (hours) of the valves of emptiness. In addition, the Reference 6 includes four sets of unbalanced analog inputs and four balanced inputs, plus pre-amplified outputs in both formats and one output for recording. An RS-232 port, an infrared input and a 12V signal trigger ensure the perfect integration of the new Audio Research preamplifier into all types of custom systems
