Radial Engineering J+4 2-channel Signal Level Driver

If you interface pro audio with low-level devices - instruments, MP3 players, computers, etc. - you need the Radial J+4. The J+4 takes incoming signals as low as 10dB and boosts them up to +4 for use in professional audio environments such as recording and broadcast studios or live touring. The J+4's 100% discrete circuitry ensures optimal signal integrity, while its active signal buffering and transformer isolation virtually eliminate noise. 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.
