Product Description

The Urei 1176LN Peak Limiter is the most widely used device of its kind. Since its inception in the late '60s, thousands have been used for applications which require precise, automatic control of peak signal levels in recording studios, disc mastering facilities, broadcast stations, sound reinforcement installations, etc. 


In the 1176LN, peak limiting is accomplished by utilizing an FET as a voltage variable resistor. A unique circuit permits severe limiting without added distortion, and the compression ratio may be optimized for various program materials.

Attack time is adjustable from less than 20 microseconds to 800 microseconds. The fast attack time is independent of program peak frequency or duration. Using the tone burst method, a 50 kHz peak is fully stabilized at the limited level within 1 cycle. The release time is also continuously adjustable on the front panel from 50 milliseconds to 1.1 seconds.

The gain structure throughout the limiter also maintains an excellent signal-to-noise ratio at normally used control settings. The front panel meter may be switched to read either the amount of gain reduction or the output signal level referenced to +4 or +8 dBm.

Provision is made to interconnect two 1176LN Limiters for those applications where two channels of program material are processed, and the balance of these audio channels must be maintained. The signal with the larger peak-to-peak amplitude will cause the same amount of gain reduction in both limiters. For this mode of operation, the accessory Model 1176SA Stereo Adapter is required. 


The majority of 1176's produced over the years have been the 'F' revision. The main distinction of this version is that the output amplifier is now switched from a class ‘A’ to a class 'AB' push-pull type, which gives it more output drive. Other characteristics remain the same as the earlier 'E' revision.

The 1176 has been used on more recordings than almost any other compressor. Beautiful on bass, vocals, guitars, etc.
