If you interface pro audio with low-level devices - instruments, MP3 players, computers, etc. - you need the Radial J+4.

The simple control set includes a stereo gain control, a highpass filter, and a ground lift. For flexibility, J+4 is fitted with dual 1/4" and RCA jacks, and an 1/8" stereo TRS input.

You could drive a truck over this box. Sounds fine, it's quiet and performs as advertised.

I use the Radial Engineering J +4 line driver to control the volume of my turntable system. Pioneer PLX100 DJ turntable into the Radial Engineering J33 turntable DI that feeds the Radial Engineering J+4 to control the Dynaudio bm5mkIII speakers. I am very pleased with the Radial Engineering products.
