These are InGenius balanced input stages. Info at: http://www.thatcorp.com/1200-series_High_CMRR_Balanced_Line_Receiver_ICs.html Maximum output level is +26dBu balanced, +21dBu unbalanced. These use OutSmarts balanced drivers. Info at: http://www.thatcorp.com/1600-series_Balanced_Line_Driver_ICs.html For the Alternate line inputs (Stereo Pgm and Line In). Max input is approx +18dBu. These have variable gain controls and can be assigned to any of the 4 outputs. The Stereo Pgm input also has Hi & Low shelving EQ. For the Announce Mic input (front & rear XLR jacks): Max input is approx +10dBu This has variable gain and can be assigned to any of the 4 outputs. It also has Hi & Low shelving EQ.
