There's Nothing Else Like It


Quiescent's extraordinary combination of electronic and structural design, materials, electronic noise reduction and acoustic noise reduction puts it in a league of one.

About The Peak Mains Module

Using the same chassis as the Mains Shunt Filer and the Peak Grounding Module, the Peak Mains Module provides another layer of defence against system-borne EMI/RFI and vibration. Used inline with either your current mains leads (will need change of plug) or using Quiescent Peak or Apex mains cables, these modules effectively provide a further reduction of RFI and acoustic vibration through your mains loom.

But you may ask yourself, why bother? Well, it's a huge upgrade and there's really no other way of achieving it, is the answer. Quiescent have found (and we agree) that significant amounts of damaging RFI and vibrational energy pass around your system along your mains leads. The Quiescent mains leads themselves can go some way to reduce this problem, but the modules, particularly as acoustic 'absorbers', provide far more mitigation. 

It's the listening tests where it counts of course, and in most systems, the addition of the Peak Mains Modules delivers an extra level of control and stability. Stability might be a strange word to use but it's when you take the modules out that such a word springs to mind. Without the modules, a system sounds a little shaky, a bit weak and not so well controlled. Dynamics are not so well delineated and useable volume is reduced. Put the modules back in and you can hear the reduction in the damaging interactions and the increase in stability.

Tech Insight

We asked Quiescent why they use the Powercon Connectors on these modules, and on their cables too (as an option). Two main reasons they said. One, they are much more efficient for space and mounting in the modules. They're essentially an axial connector, so they're much slimmer than normal mains plugs and sockets. This enables the option of two outlets on the module and also helps considerably with keeping the mains loom in a large system manageable (using several modules say).

The second reason is connection quality and durability. Contact resistance is very low and the connectors lock tightly so they stay 'fully home'. They are designed to be tough and reliable, rated as good for many hundreds of connects/disconnects, but this robustness suits Quiescent's purposes for an additional reason – it allows the efficient conduction of acoustics from the cable and into the module, where it can be effectively absorbed.

Matching & Setup

Deploying the Peak Mains Modules in a system requires some planning. For initial testing you can test one or two, with the appropriate leads, in the main feed to your distribution block or a power amp say. But for full system deployment, say with a distribution block input and then four components, then floorspace and cable routing needs careful layout. You can check the module dimensions in the specs, and Quiescent have made the case design so that two or more modules can be very neatly stacked. You also have a choice between single-output or double-output modules – with the double output option you could service four source components with two modules.
