What is it?A 4-in, 16-out active splitter suitable for rental, touring, live sound and fixed installations in venues and theatres. DetailsDesigned for any application that requires audio signals to be split and fed to multiple destinations, the 1U rack-mountable 4x4R has four inputs and 16 balanced outputs, with a transparent mic preamp on each input offering up to 66dB of gain. The 4x4R’s I/O may be flexibly configured in a variety of ways, ranging from a single input routed to all 16 outputs to four different inputs, each with four outputs, or any configuration in between - for example, two different inputs, each routed to eight outputs. In addition to the comprehensive input/output linking, the 4x4R features bargraph metering, switchable phantom power on every input channel and a front-panel headphone jack for monitoring of any of the four inputs. The option of transformer isolation is also available for some or all of the outputs.
