Enhancer / filter
bought a year ago
Easy to use to increase the depth of bass and treble definition. Adjustable sub output.
What I like most: only 4 settings per channel and 2 for the sub output, so very easy to adjust (unlike some higher-end models that are sometimes real gas works hard to settle for a novice) .
Minimum: the minimum setting of "low-mix" strengthens the already very low, so do not have a source with low already too strong, and you must activate the bypass in this case because if the bass become unpleasant.
Other settings (the output sub) are "measured" (mini and maxi low enough high enough).
Tried on a lot of different configs, it effectively increases the sound quality on low-end sytems. The output sub is very practical and effective.
proper value for money (bought a few more € 100 1 year ago)
The connector input / output is XLR only, so always have a variety of different cables and adapters to integrate it into another config in the evening.

In the future I would buy a model probably a little more upscale for fine adjustments. But I think this one use for a long time that is convenient for parties notament
