Nordost QRT | Qx2 Power Purifier

Audio/Video components, regardless of their quality, are overwhelmingly susceptible to performance degradation due to contaminated AC power. In today’s modern society, where electrical devices and appliances now occupy every free outlet in our houses, the problem of AC contamination is becoming more evident than ever. Electrical spikes, frequency variations, impulsive and oscillatory transients and noise are some of the side-effects that can drastically impact the outcome of your sound system if this current pollution is not addressed. Unfortunately, attempts to clean the AC line through the use of power conditioners often cause more problems than solutions, limiting bandwidth and losing information through filters. Nordost’s power purifiers offer all of the solutions of conditioners without any of the compromises. QX  units are active field generators designed to remove noise and cure waveform inaccuracies and voltage fluctuations in the AC line without compromising peak currents, raising source impedance, or reducing bandwidth.

Each QX  unit is comprised of a mechanically tuned, extruded aluminum casing, which houses two or four electromagnetic field stabilizers (EMFS). When the AC line flows into the QX  unit it passes directly through the field generated by the EMFS, which strips the current of EMI and RF interference. Since these harmful attributes can be excluded without having to reconstruct the signal, as is normally done with typical power conditioners, Nordost QX  units are able to improve the consistency and regularity of the waveform and reduce timing errors while maintaining the original bandwidth of the signal. With QX  unit(s) in place in your system, you will experience a lower noise floor, greater dynamic range, and a more fluid musical expression that will allow you to appreciate the dimension that your system is capable of portraying. These improvements are not solely emotional in effect; the results of QX  units can also be empirically proven. When tested in an auditory application, the QX  showed a signal-to-noise increase of 15%. Similarly, when tested in a visual application, the QX  unit showed an improvement of 15% in color saturation.

Nordost’s QX units vary in the number of EMFS generators that are provided, using two in the Qx2 model and four in the Qx4 model, which boasts twice the efficiency.

While QX  units are effective as stand-alone components within your sound system, their results are only magnified when multiple units are used together and when combined with the rest of the QRT family.
