The Gyraf Audio GY 4.5 Inherit Cartridge

Faithful to the original in every detail, the GC Audio GY 4.5 is a genuine tube preamplifier. It comes with two ECC82 tubes running on high voltage, with no solid-state components in the signal path.

Overview by Jakob Erland

“The preamp-as-a-cartridge is simply a great idea: In this day and age where you can have clean and neutral preamps virtually for free with your converters, you don’t want a big stack of the same type preamp – you want variety, something that matches the individual microphones and sources you are working with. The inherit cartridge system gives you exactly this – the ease of trying out a variety of flavors – the possibility of finding that sonic imprint that’s just right for what you have at hand. The G9, which the GY 4.5 cartridge is based on, is an adaptation of the input circuit of the G36 tape recorder, that I have used and loved since I was a kid. Update includes transformer balancing in and outputs, phantom power, switchable high-pass filter, and switched gain settings.”

The GC AUDIO Gyraf Audio GY 4.5 Inherit Cartridge is a versatile and high-quality preamp that offers a range of sound options, making it a valuable addition to any studio setup
