What is it?An upgrade to the Si range of mixing consoles. DetailsThe Si1 has been re-designated the Si1+ and features 16 additional inputs fitted as standard bringing the overall number of onboard microphone inputs to 48 with an inputs-to-mix processing capacity of 72. Alternatively, the extra 16-mic input module may be replaced by an 8-in/8-out module, if required. The number of optional card slots has been increased to four, and there is now also space for a second (redundant) PSU which can also be fitted as an option. The Si2+ is also fitted with the 16 mic input module as standard (this again is swappable with the 8-in/8-out module), which extends the onboard mic input count to 64 with an input-to-mix capacity of 80. All three desks – including the Si3+ – are now fitted with a word clock output connector, and all models can use the range of optional Si interface cards including MADI (optical or Cat5), AES/EBU, CobraNet and Aviom A-Net.
