Zen Line Conditioner

Zen Line Conditioner by DECWARE

Model ZLC

The ZLC is a power conditioner for your Decware gear.

It improves liquidity by removing noise and harmonics in the power grid feeding your home.


The Zen Line Conditioner uses a giant toroidal isolation transformer to store and release energy to your equipment.  It 100% de-couples whatever is plugged into it from the noisy power grid that contaminates the sound quality of your gear.

The result is better dimensionality, far better liquidity, an absence of grain and better dynamics made possible by the large toroid.

  • The internal components are soldered. 

  • The wire is top grade THHN stranded copper. 

  • The outlets are hospital grade.

  • 6 receptacles each individually switched.

  • Star Grounding.

  • Spike protection.

  • Increased safety for you and your equipment.

  • Heavy steel case.

  • Powder Coat Finish.


One of the biggest headaches in the hobby of high-end audio is noise and hum. The largest contributor is having your equipment plugged into several places, or into power strips, which have similar results.  When components have a different resistance to ground from being plugged into different outlets or power strips, you can have ground loops that cause hum.

Having everything plugged into a single place, like the Zen Line Conditioner, creates a single-point ground scheme that can eliminate ground loop related hum issues, but also improves the sound of your entire system with blacker backgrounds.



The Zen Line Conditioner features heavily shielded noise filtration on the input IEC device to kill incoming noise and keep it from reaching the inside of the steel cabinet where the toroidal transformer lives. Once the power is cleaned, the transformer magnetically decouples it and then feeds the various outputs. A single cap is used on the secondary to multiply the noise rejection without creating any artifacts. 


The power grid for any area is noisy.  It has thousands of spikes from motors and other things turning on and off all over the county.  It is also saturated with microwave RF from cell towers as is your home.  While it is possible to filter a lot of this out, it is not possible to get all of it.  Some would rationalize that this is OK, but in reality it is like saying that it's OK that we got 94% of the water out of your gas.   ZLC is a good way to completely de-couple yourself from the grid. 


Isolation transformers come in two flavors,  E-Core and Toroidal.  E-Core is less expensive square transformer that vibrate proportional to their size and the load placed on them.  So if you use an E-Core you will hear 60 cycle vibration from the transformer with anything other than small amplifiers and preamps.  Toroidal transformers also vibrate, just that they do it less at the same amount of load.  

Vibration and apparent mechanical hum are proportional to the load applied to the Zen Line Conditioner.  While it is rated at 8 amps you will start to hear a low level vibration at around 4 amps.    This is generally not an issue with Decware gear because our amplifiers draw  between 0.6 and 1.2 amps.

Using this isolation transformer with large power amps may result in mechanical vibration, far less than the same current on an E-Core transformer but still enough that you will probably hear it.


It is a common misconception that dirty power somehow causes noise and or hum in audio gear.  It doesn't.  It causes dryness and grain in the music and compromises dimensionality.  If your system hums loud enough to be heard at the listening chair against the normal noise floor in a home than you need to figure out why.  Don't buy this product thinking it will fix the hum in your system because unless you have ground loops, it's not likely to have any effect on it.  The sound quality of your music will still be a lot better with this product despite the hum your equipment might have.
