Thank YOU for purchasing the Lindell Audio 7X-500 Compressor/Limiter!
The Seven X Five Hundred is a one channel compressor/limiter. It’s a FET (field effect transistor)
design that incorporate some new and exclusive features such as
”High Pass Sidechain Filter”, ”Mix Knob” mix between dry and wet signal (parallel compression).
The 7X-500 is our take on the classic ”1176 Sound”. It can be smooth or it can be a
rock’n'roll monster when using ratio 100:1 (all in).
The 7X-500 fits in all 500 series compatible power supplies.
