RADIAL ENGINEERING J+4 Direct boxes - Stereo converter - 10/+4dB
Direct Boxes - Stereo Converter - 10/+4dB
Special attention has been paid to eliminating 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 or ground noise loops do not pollute the signal. Controls have been kept to a minimum. This includes a handy stereo level control, low cut filter and ground lift. The input connector section includes a set of stacked 1/4" jacks with jacks for DJ mixers or keyboards, RCAs 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 touring. Its steel case and inner frame give this product a high degree of rigidity. Another innovative feature is the book-shaped shell that creates protective zones around controls, switches and connectors to push the limits of reliability even further. The Radial J+4 offers exceptional sonic performance, fabulous headroom and delivers ultra low noise. This makes it the ideal companion for the most demanding professional audio systems.
