T500VA Balanced Mains Supply
“Michael Hedges’ 1984 recording Aerial Boundaries, stunning before, both for its virtuosity and the quality of the recording, took on new meaning as the enhanced level of dynamic expression turned the individual string plucks on his acoustic guitar into events of intensely focused in-room energy. The noise floor had dropped even further away and there was a heightened sense of musical flow.”
The T500VA mains conditioner provides benchmark mains distribution at the heart of any audio system. Deploying highly innovative technology developed from the ground up, the result is an exceptionally quiet and non-intrusive approach to clean power. With our patented, massive anti-vibration and RFI/EMI absorption technology at its core, damaging mechanical, EMI and RFI energy is drained from the mains input and between each component within the audio system.
The T500VA was developed after a review of our highly acclaimed mains distribution blocks and distribution units.
Like all other Quiescent components, significant attention was given to reducing system-wide noise and vibration propagation effects. 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 also add to the signal through self-induced microphonic noise, radio frequency propagation, and electromagnetic interference. Using our patented QPower™ system directly coupled to a Quiescent-specified custom-wound balanced toroid transformer, the noise floor of the mains is lowered to such levels that all components are transformed.
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 our custom-wound transformer to ensure that when it needs to provide power, it does so with minimum vibration to prevent mechanical energy cascading in the system. We have also incorporated our d.c blocking mechanisms to ensure any mains d.c. offset does not oversaturate the transformer and cause any audible humming, which is common in households. To block d.c., we do not use a simple choke (inductor) as this usually always results in energy loss to the downstream components. Our d.c. blocker performs the function without acting as a choke. This ensures an abundance of power is supplied without any hindrance. The transformer is fully coupled using our patented QPower™ vibration absorption technology 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 devices are placed between the non-balanced and balanced sections. Direct and balanced outputs are then mounted on separated sub-panels decoupled from the chassis to ensure maximum socket isolation.
The massive, low-resonance, custom-built chassis is machined to such tolerances that, assembled, they appear to be 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 Quiescent has become recognised.
This results in an exceptionally clean and stable mains distribution system that allows other components to perform at their maximum potential.
