EMT 277 DX extended range Limiter 1970s

EMT 277 DX-Limiter – Precision Analog Limiter from Classic German Broadcast TechnologyThe EMT 277 DX-Limiter originates from the peak era of German broadcast and measurement technology and was developed by EMT Wilhelm Franz in Germany as a high-quality, extremely reliable analog limiter. It was not a mass-produced device, but a technically sophisticated specialty unit featuring modular plug-in cards, fully discrete design, premium components, and exceptional build quality. At the time, original pricing was comparable to top-tier professional studio equipment – accordingly, well-preserved and technically maintained units are rare today.What makes the EMT 277 special is the combination of highly precise analog control circuitry, exceptional speed (look-ahead / transient limiter behavior), and an extraordinarily neutral sonic performance — not clinical, but naturally transparent and musically unobtrusive. It acts before signal peaks can color the audio or overload technical equipment, delivering a clean, dynamically stable signal with an unchanged sonic character.Key Features• Analog transient limiter principle with look-ahead technology• Extremely fast response time without audible distortion• Neutral, transparent sound without added coloration or compression artifacts• Program-adaptive release times to maximize average signal level• Optional bandpass filter (e.g. 80 Hz–4.5 kHz)• Robust, fully discrete construction – serviceable and maintenance-friendly• Rare original unit from German broadcast manufacturing (EMT Wilhelm Franz GmbH)

I have two identical 277 DX compressors. If you are interested in a stereo pair email me.
