T-500VA Mains Balanced Power Supply Unit

Technology

The T-500VA has been developed after a complete review of our highly acclaimed mains distribution blocks and distribution units.

Like all other Quiescent components, significant attention has been spent on reducing the effects of system-wide noise and vibration propagation. While the impact of poor mains on audio systems is well understood, most techniques for dealing with poor mains cause other unwanted loss of information. Systems are also known to add to the signal through self-induced microphonic noise and the propagation of radio frequency and electromagnetic interference. Using our patented QPower™ module directly coupled to a Quiescent-specified 500VA custom-wound balanced toroid transformer, the noise floor of the mains is lowered to such levels that the components are transformed.

Technology

Mains-borne noise and cross-talk between system components is a problem well-known to enthusiasts and designers alike. The T-Series is a unique solution to this problem because it deploys extremely quiet, non-intrusive technology to isolate system components from each other and the external environment in which they operate.

We have paid meticulous attention to the choice of the transformer to ensure that when our custom-wound 500VA transformer needs to provide power, it does so with minimum vibration to ensure that the mechanical energy is not cascaded in the system. We have also incorporated our d.c blocking mechanisms to ensure that any mains d.c. offset does not oversaturate the transformer and cause any audible humming, which seems to be so common to households. To block d.c., we do not use a simple choke (inductor) as this usually always results in loss of energy to the downstream components. Our d.c. blocker performs the function without acting as a choke to ensure an abundance of power is supplied without any hindrance. The transformer is fully coupled using our patented QPower™ vibration absorption technology in order to prevent ultra-sonic vibration and EMI/RFI.

To ensure that the source components connected to the balanced outputs are fully isolated from the current-needy power amplifiers connected to the direct sockets, full EMI/RFI and mechanical decoupling is placed between the non-balanced and balanced sections. Direct and balanced outputs are then mounted on separated sub-panels that are decoupled from the chassis to ensure maximum socket isolation.
The massive, low-resonance, custom-built chassis is machined to such tolerances that each panel becomes a single block. We carefully place the fixing bolts, making it an inert chamber immune to any influence from the external environment, no matter how loud the music. Finally, the entire chassis is machined with our disruptive patterns and surfaces, for which Queiscent has become recognised.

All of this results in an exceptionally clean and stable mains distribution system that allows other components to perform at their maximum potential.
