General

DBX equalizers have been the studio, audio, and touring industry standard for a long time now, which is little surprise, since they've been pushing out the same level of quality for a good forty years now. As such, the DBX 131S equalizer is part a legacy of renowned, pro-grade EQs and is guaranteed to meet the requirements of even the most demanding audio-based jobs. Lined from the left all the way to the right with frequency sliders, it's also incredibly easy to use.

A Flying Tour of the DBX 131S

The DBX 131S very simply sets you up with a single 31-band channel with 1/3-octave equalization that's been combined with ±12dB input amplification and a ±6 dB or ±12 dB boost/cut switch. The bank of 20mm sliders give you tactile, intuitive, and direct power over the entire frequency spectrum, while the set of VU meters for the output lend clear support. The extensive frequency response of 10Hz to 50kHz and the 110dB dynamic range only serve to confirm the quality components and attention to detail that has gone into building this uncompromising unit.

The Professional Equalizer

In short, the 131S offers exceptional sound and solid reliability, setting up your audio system with nothing but the best. The 131S feels most at home in studios, on the road, and as part of audio installations, and is a more-than worthy addition to the already stellar DBX signal processing line-up.

Wrote the following about DBX 131S Equalizer

De DBX 131S is een hele goede equalizer, de geluidskwaliteit is zeer goed, je kan er heel precies je muziek mee perfectioneren, en ik vind het heel handig dat je er volume mee kan aanpassen, dat betekent dat als je je equalizer aansluit op je pc, je het volme van je muziek kan beïnvloeden, zonder dat je op de grond hoeft te gaan liggen om het volume van je actieve speakers aan te passen.

Het is wel mono, wat betekent dat je niet kan beïnvloeden hoe sterk links of rechts klinkt (tenzij je een versterker erop aansluit).

Het product was ruim op tijd geleverd, zoals altijd,
