Our Thoughts RADAR AI

€130 is a fair-to-good ask for a clean 131S, and in excellent condition it’s comfortably buyable rather than stretched. New retail for this unit sits around the low-€200s, so €130 lands at a sensible used discount without being a steal-level bargain; I’d call it a solid fair price if it’s fully working and tidy.

It’s a straightforward, well-regarded 1/3-octave mono graphic EQ: useful for system tuning, taming room issues, or slotting into a live/hi-fi rig without fuss. The 131S’s balanced I/O, bypass, and internal PSU make it practical, and “excellent” condition matters here because a clean fader bank and quiet electronics are the real value. If it includes rack ears or original extras, that nudges it a bit better still.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About DBX

Founded in 1971 in the United States by audio engineer David Blackmer, dbx emerged from his pioneering work in dynamic range processing. Blackmer, whose initials inspired the brand name, initially developed decibel expansion technology to enhance audio fidelity, aiming to capture the realism of live performances. The company's early innovations, including the dbx 202 "Boom Box" bass amplifier and the iconic dbx 160 compressor/limiter, quickly established it as a staple in professional studios and live racks during the 1970s and 1980s.

dbx specializes in professional audio signal processing equipment, with a legacy built on compressors, limiters, and noise reduction systems. Its lineup has expanded to include microphone preamps like the 286s, speaker management systems such as the DriveRack PA2, and modern rackmount processors in the CX and 500 Series. While it briefly ventured into consumer gear like speakers and amplifiers under BSR ownership in the late 1970s, dbx has steadfastly focused on pro-audio tools leveraging proprietary technologies like True RMS detection.

Now a division of Harman International (under Samsung), dbx holds a respected mid-tier position in the professional audio market, prized by engineers for reliable, workhorse dynamics control in broadcasting, live sound, and recording. Vintage models remain collector favorites, but current offerings compete effectively against digital rivals, blending heritage innovation with robust build quality for demanding applications.
