The URS 1970��s Classic Console Compressor features digital recreation of transformer input and diode bridge gain reduction amplifier characteristics. 
Smooth and warm!

High Res 48 bit "Double Precision" processing
The URS Classic Console Compressors TDM versions feature Hi Resolution 48-bit TDM and 64-bit RTAS 
"Double Precision" processing for increased clarity, headroom and unparalleled gain reduction.  Hi Resolution "Double Precision" processing helps to avoid internal clipping in the Digital Domain. 

Independent Compressor and Limiter sections
The Compressor and Limiter sections are totally independent of each other.  Both feature separate variable Attack, Release and Threshold controls. 

Built in Internal Side Chain Filtering
The Internal Side Chain High and Low Pass Filters fine tune how narrow or "Broad Band" the URS Classic Console Compressor will affect the program material.  Both Filters completely overlap to dial in problem frequencies.

Listen Key
The Listen Key is after the Filters section. The Listen Key allows you to monitor the signal being sent to the Gain Reduction detection circuit. 

Signal Flow explained
The URS Classic Console Compressors signal flow inserts the Gain Makeup control before the final Limiter.  This is the secret  to how hard you can hit the final "Brick Wall" Limiter.  The URS Classic Console Compressors utilize Feed-back gain sensing.  Feed-back gain sensing gives Compression and Limiting a servo type of control.  See the detailed signal flow diagram below.

Classic Sound with Modern Features
The URS Classic Console Compressor adds other powerful modern features such as totally variable Compression Ratios, Attack and Release times. 

Two  Different Plug-ins 
Two different URS 1970 Classic Console Compressor plug-ins are included in this bundle. 

The 1970 version includes : 
� Compressor/ Limiter / Side Chain version 
� Compressor only version 

The 1970 Compressor /Limiter / Side chain version has a "Brick Wall Limiter to smooth out the most difficult musical tracks. The 1970 Compressor /Limiter / Side chain version is well suited for Drum Sub Groups, Aux sends (TDM versions) and especially on the Mix Bus. 

The 1970 Compressor only version is 3x more DSP efficient.  The Compressor only version is very well suited on general instruments, such as vocals, guitars, bass and individual drums. The 1970 Compressor Only version will act as a Limiter when the ratio is set at 10:1 and above.
