    The Multi-Split unit’s flash memory holds up to 10 complete configurations, which users can load as required. Unlike comparable products, ITEC’s devices work with an analog signal path (except for the optional DSP output modules), which is fully digitally controlled. The processors control the VCAs, measure levels and transmitters and switch the signals.
