The Peavey Q Factor Dynamic Noise Reduction System does not exist as a standalone hardware product or an official feature in Peavey's catalog. The name appears to be a mashup of several distinct audio engineering terms and separate Peavey product lines.

If you are looking at a specific piece of secondhand audio gear or a manual, you are likely cross-referencing or misremembering a combination of the following distinct concepts:

1. Peavey "Q" Series Equalizers (Constant-Q Filters) Peavey manufactured a highly successful line of graphic equalizers throughout the 1990s and 2000s, including models like the QF 215, Q231F, and Q431FX. These units heavily advertised Constant-Q filters. In equalizer design, the "Q factor" (Quality Factor) determines how tightly or broadly a slider affects neighboring frequencies. A Constant-Q design ensures that narrowing or boosting a frequency band maintains a precise bandwidth regardless of the fader's position.

2. Peavey's Built-In Noise Gates (Invective Series)

Peavey is famous for its high-gain guitar amplifiers, such as the 6505 and the newer Invective series designed with Misha Mansoor. These modern heads feature a highly regarded, fast-attack input noise gate with an adjustable threshold built directly into the preamp circuit to filter out dynamic high-gain hiss and hum.

3. Dynamic Noise Reduction (DNR) Systems

"Dynamic Noise Reduction" is a specific, generic analog audio technology popularized by National Semiconductor (and used extensively by brands like Rocktron with their HUSH systems or Intersil). A DNR system functions as a dynamic, program-dependent low-pass filter. It works by analyzing the incoming audio signal: when the music gets quiet, it automatically rolls off the high frequencies where background tape hiss or system noise lives, opening back up instantly when a loud signal passes through.

4. Peavey "Q Factor" Large-Format Loudspeakers

Peavey previously used the designation "Q Factor" for lines of high-end, large-scale venue speaker enclosures—such as the Peavey Q Factor 2212 and 218 subwoofers. These were passive sound reinforcement cabinets built for outdoor amphitheaters and venues, completely unrelated to signal processing or noise gates.

This does not come with power adapter or manuals.
