The J + 4 is a stereo interface specifically designed to pick up the low-level, unbalanced signal output from an instrument, computer, or mobile device, to turn it into a +4 dB symmetric signal compatible with professional sound and recording systems.The RADIAL J + 4 is a stereo interface designed to accept unbalanced signals - 10dB - general public - high impedance and convert them to symmetrical signals + 4dB low impedance for easy management in environments professionals, such as broadcasting, recording studios and live touring recordings. Special attention has been paid to eliminate noise by combining the advantages of an active signal buffer with an isolation transformer. The J + 4 offers a signal-to-noise ratio better than 95dB, while ensuring that the 'hum and buzz' caused by clock noise loops, or ground loops, do not pollute the signal. Controls have been reduced to a minimum. This includes a convenient stereo level control, low cut filter and ground lift. The Input Connector section includes a stacked 6.35mm jackset with jacks for DJ mixers or keyboards, RCA for CD players, and a 3.5mm mini jack for iPods.
Like all RADIAL products, the J + 4 is built to withstand the extreme rigors of professional tours. Its steel case and its internal frame give this product a rigidity foolproof. Another innovative aspect is its book-shaped shell, which creates zones of protection around controls, switches and connectors to push the limits of reliability even further. Finally its 'pad' coating offers both mechanical and electrical insulation.
The Radial J + 4 offers exceptional sound performance, a fabulous headroom and delivers ultra low noise. This makes it the perfect companion for the most advanced professional audio systems.
