Analog audio I/O
The eight quarter-inch analog inputs and outputs
(Figure 4-7) are balanced (TRS) connectors that
can also accept an unbalanced plug.
The quarter-inch outputs are calibrated to produce
a +4 dBu line level output signal.
Quarter-inch analog input trims
The quarter-inch inputs are calibrated to
accommodate either +4 or -10 dBu signals and are
equipped with digitally controlled analog trims
that provide +22 dB of gain and -12 dB of cut. To
adjust these trims, see "Analog input trims" on
page 44.
AES/EBU digital audio I/O
The HDX-SDI provides eight channels of 24-bit
AES/EBU digital audio input and output at
standard sample rates from 44.1 kHz up to 96 kHz.
