NTP 179-170 Stereo Compressor / Limiter / Expander – Danish Broadcast Classic

Up for sale is an NTP 179-170, the dual-channel 19" 1U version of NTP's 179-160 dynamics processor, made in Denmark. It combines three instruments in one: a limiter for high-level signals, a mid-range compressor/expander for the desired dynamic range, and a low-level expander to keep noise down. It is built around NTP's own high-quality VCA module, which allows extensive filtering of the control voltage. That is widely credited for its distinctive sound. Features per channel: Compressor/expander mode switch Threshold, ratio (1.3–10), attack (ms range) and recovery time with AUTO (program-dependent) release Gate/low-level expander with Slow/Medium/Fast gate time Front-panel preset trims for limiter threshold, reference level, output level and gate function LED meter for gain/attenuation and limiter activity Hard bypass per channel Linking and I/O: Stereo linking via Group A/B switches Rear "Control voltage grouping" connector for linking multiple units Balanced XLR inputs and outputs IEC mains inlet with 230/115 V selector Condition: very good The 179-170 is rarely offered and comes from the same family as the famous 179-120. It works equally well as a transparent bus compressor and as a creative expander. Shipping: well packed, insured, from Germany. Questions welcome.
