Vintage equaliser from UREI. The 546 is a two-channel, four band parametric equaliser with variable high- and low-pass filters and input gain controls. In usual UREI fashion, the ergonomics and signal path have been honed to perfection , producing a highly useable, efficient EQ

Each band has a push-pull, in / out switch to bypass that band only. Each channel has a bypass switch and this 546 has been modified with a filter bypass switches. In bypass bandwidth is extended to 200 KHz

The 546 is easy to use with plenty of scope in the controls and well-judged linearity. The tightest filter setting has a high Q is suitable for notching out problem frequencies. At broader settings each band is wider & smoother. The 546 turns out to be my favourite bass equaliser – it’s easy to put weight into a bass sound, or warmth, or depth without it sounding wooly

“There’s also a certain curiosity factor with this eq. Every engineer that’s been in my studio since I got it has immediately zoned in on the 546 and been intrigued with it. There were only about 1,000 made, I believe, so it’s not something everyone has seen”

“Very useful piece of gear IMHO! Good for notching out annoying freq’s in guitars/vocals. You may find you like on a variety of sources”

“A friend was clearing out his studio of older stuff and gave me his a few years ago. It sounds good, great for bass, guitars or vocals. Mine seems a bit sensitive to overload, probably needs new caps.

The 546 was original UREI [United Recording Electronics Industries] gear from their Sun Valley days, and was pre – JBL. I think 70’s.”

“It’s a great parametric EQ for the price that they seem to fetch. They do not have a lot of headroom (which is a problem with lots of parametrics) but you can generally work around it. Not a warm or sweet sounding EQ but great for surgical stuff like fixing bad kicks, vocals, etc”

In very good used condition. Has minor rack rash & case marks but it’s in great shape for a vintage piece. All knobs are original & in good condition excepting channel A low-frequency knob which has a chip out of the transparent surround. Refurbished & recapped. Tested & working 100%.
