The Radial ProD8 is an 8 channel 19″ rack-mountable direct box designed for professional concert touring. The feature set has been optimized for keyboards but as with any direct box, it is certainly suitable for use with instruments or playback systems. The passive signal path incorporates a custom wound Eclipse ET-DB2 transformer and RF filtering that is able to withstand excessive signal levels without distortion while delivering a linear response across the audio spectrum.
