The USB Bal Box provides high quality balanced audio on XLR. The unit requires no drivers for current USB devices and ensures clean audio from your system with selectable Stereo/Mono and Ground lift switching.
The USB AiO has an output stage similar to the Bal Box but includes an output level control and an input consisting of 2x XLRs with Mic/Line selection and a level control on each input. A Clip LED provides visual indication to the technician if the level is too high.
The SoundConnect is a passive audio balancing unit designed to fit in to a standard XLR fixing; ideal for wall & lecterns and has a simple connection for computers and iPads alike.
