What Our Customers Say

The PEQ1549 is probably the most universal 500 EQ available with seventeen manual settings and an out-of-competition sound. The 35kHz Air mode is the most extraordinary range.

–Peter Neuber, Germany, vintagemastering.com

“The RTZ 9762A preamps have become my most used preamps in a studio full of 80+ diverse, vintage, and modern options. It has a very detailed but not harsh top, with a clear and full bottom without mud, the 9762a stacks up very favorably (most often being the better choice) against many options costing 4 and 5 times more. The mids from your mic choices are really neutral giving the listener that “in the room” craving, that I myself, am always trying to achieve in my productions. I’m a 100% satisfied customer here, owning 12 channels so far. Give them a try yourself and don’t be afraid to try and outgun them, but good luck in doing so.”
