The original Fairchild 670 has a reputation as the best sounding and most versatile compressor ever made. Used on countless hit recordings over the years, its unique combination of tube driven amplification and gain reduction gives the 670 a wide range of compression effects, from subtle and transparent to heavy and pumping. The new vacuum tube Fairchild 670 compressor is faithfully recreated to provide modern producers and audio engineers with the classic sound of the first intelligent automatic volume control limiter. With its dual-channel design and unique compression characteristics, the Fairchild 670 is capable of adding warmth, depth, and character to virtually any audio signal. The vacuum tube technology used in the 670 adds a natural, organic quality to the compressed signal, providing that distinctive classic analogue sound to both digital and analog productions.<\/p>\n
