2005年8月25日 · Nice squish, thick, introduces a bit of hair. Great on vocal, guitars of all sizes, fun room mic or over head. I have used it everywhere it all depends. You can use it just a touch or really sit on things with it. If you think something should start getting low passed around 8K this is a nice box for that. Can you tune “that” to “this” key?

70s Urei, basically LA-3A opto + 1176 fet comps in one unit, uses all the same custom urei transformers for the inputs and outputs as used in la3a's and 1176 rev F. Original T4C opto cell. Has the popular added knobs mod. Great sounding unit all working. Check out the demo video.

UREI BL-40 in good condition. Just serviced. Listed as “good condition” since the “on” light does not work, but everything else is as it should be. Sounds beautiful. Great piece. I ship FedEx only. Let me know if you have any questions. Reverb has your back if your item is lost, damaged, or doesn't match its description.

~he BL- 40 employs UREI's patented electro-optical attenuator (T4C) for unobstrusive, smooth, true RMS limiting (U.S. Patent 3.258.707). It controls the signal level by measuring m1s content and adjusting the gain to produce a constant power output.

70s Urei BL40 modulimiter, essentially an LA3A opto comp section + 1176 fet limiting section in one unit feeding into each other in series, with controls to vary the blend of each. Has knobs and XLRs unlike most others. Original T4C cell. Fully working order, sounds great. Best BL40 anywhere and best price.

The BL 40 Modulimiter was originally designed for broadcast use in AM radio stations, and acts like a combination of the solid state opto-cell LA-3A and the classic FET 1176 units. A T4 opto-cell acts as the RMS detector, and provides the first stage o.

The BL-40 is a complex and very interesting limiter that was manufactured by UREI in the late 1970's. Essentially it's an LA-3A Optical limiter combined with a 1176LN FET type limiter. Your audio input hits the LA-3A section first, then passes through the FET limiter section. These models were mainly used by radio broadcasters.
