In that period the 1176 and LA-2A had already established themselves as a must for every studio yet they were no longer in production and were hard to find. The original hardware unit (father of the Impresser) was designed in the early 90s and reflected its time. Like all Antelope Audio FPGA compressor models, you can use the Impresser either in mono or with two channels stereo linked. This enables even deeper control when shaping the frequency range for where you need the Impresser to work. Our own contribution to the effect is the adjustable frequency settings for the High and Band Pass Sidechain Filters. It works its magic with or without the Impresser compressing the signal. This can be used for subtle, tube-quality distortion and even in place of a tape saturator. The flexibility of Impresser is aided by the addition of its own harmonic distortion. Impresser can add gentle and warm compression to your tracks or aggressively pump up any source audio.
