SW8™ Specifications

The Radial SW8 is an 8-channel auto-switcher designed to switch balanced and unbalance audio sources and deliver them via a straight wire or transformer coupled interface. As solid wire specifications cannot be measured, the graphs below depict the performance of the SW8 using the transformer isolated XLR outputs. it is also important to note that the direct box outputs are designed to reduce a +4dB balanced source to a lower mic level source, thus resulting in a -20dB drop in level. This enables the SW8 to be used in a typical snake system without fear or overload and crosstalk.
