16、e unit shall be a digital mix processor with 12 analogue inputs and 8 analogue outputs. The unit shall have a full crosspoint matrix, comprising 96 points, allowing any input, or combination of inputs, to be routed to any output or combination of outputs. All crosspoints shall have a variable level.

17、 The 8 mic/line inputs and 8 line level outputs shall be on balanced XLRs with level trims. The 4 stereo line inputs shall sum to mono and be on RCA phono connectors with level trims. Comprehensive ducking capability shall be provided. The mic/line inputs shall have internal jumpers for pad and phan

18、tom power selection. The mic/line gain range shall be 18dB to 60dB with input impedance of 2k? (no pad) or 10k? (pad). The phono input gain sensitivity shall be internally adjustable from -10dBv to +4dBu with an impedance of 10k?. The inputs shall be converted using a 24 bit analogue-to-digital conv

19、erter. The XLR outputs shall have a variable senitivity from -10dBV to +4dBu with an output impedance of 50?. The conversion shall be by a 20 bit digital-to-analogue converter. The unit shall be configured over a standard RS232 port using a proprietary 32-bit Windows based software application with a Graphical User Interface. Configurations shall be editable both on and off-line. The configuration s
