Features
-Original Design -Circa 1969
-The Fastest Analog Compressor/Limiter
(100 Nanoseconds to 2.0 Microseconds)                    
-Ultra Low Noise - Not Less Than 80dB Below +4dBu Output With -40dBu Input
(Threshold), 20Hz to 20kHz, Unweighted.                                                                                              
-Input/Output Transformer Isolation, Frequency Response, +/- .1dB, 20Hz to 20kHz, @ +16dBu
                                           

Input Impedance                              600 ohms
Output Impedance                           Appoximately 120 ohms (1 kHz), Floating
Output Loading                                600 ohms to Infinity, balanced or unbalanced
Maximum Gain                                56 dB
Input Level                                     Typically -50 dBu to +10 dBu
Threshold Attack Level                    -40 dBu
Output level                                    Typically +4 dBu or +8 dBu
Frequency Response                        +/- .1 dB, 20 Hz to 40 kHz, at +16 dB 
                                                      (High Z Load)
                                                      +/- .5 dB, 20 Hz to 20 kHz, at +16 dBu 
                                                      (600 ohm load)
Harmonic Distortion                        Less than 1/10 of 1%, 30 Hz to 20kHz, at +16 dBu,
                                                      up to 30 dB compression, with release time such
                                                      that attack and release does not occur on successive
                                                      peaks of the lowest frequency utilized. (Typically 
                                                      less than 5/100ths of 1%)    
Compression/Limiting Ratio              Continuously Variable from approximately 1.1:1
                                                      to 100:1
Attack Time (Automatically Variable)
                        Limiter                   100 nanoseconds to 2.0 microseconds

Release Time For 90% Recovery     
                        Limiter                    Less than 90 nanoseconds
                        Compressor             Continuously variable from 50 milliseconds
                                                      to more than 10 seconds
Maximum Temperature                    140 degrees Farenheit
