Connect Audio Inputs And Outputs - MOTU V4HD User Manual

CONNECT AUDIO INPUTS AND OUTPUTS

The V4HD provides 32 channels of simultaneous
audio input and output (Figure 3-5), grouped in
four banks of eight channels each: analog,
AES/EBU, optical and embedded (for SDI and
HDMI out). For connecting the first three banks,
see the following sections. For embedded, make
the SDI and/or HDMI connections as described
earlier and then enable embedded audio. See "SDI
Input and SDI/HDMI Output" on page 75.
Analog audio I/O
The V4HD provides eight channels of analog audio
input and output at standard sample rates from
44.1kHz up to 192kHz.
4-channel operation
As shown in Figure 3-5, the Analog Input section
and Analog output section each supply four XLR
connectors directly on the rear panel. These input
and output jacks provide four channels each of
analog input and output via direct connection to
the V4HD rear panel using standard XLR cables.
8-channel operation
If you need eight channels of analog input or
output, a DB25-to-XLR breakout cable
(Figure 3-6) is required (sold separately).
Optical digital I/O
Figure 3-5: The V4HD audio connectors.
24
For eight channels of analog input, the breakout
cable requires a male DB25 connector on one end
and eight female XLR connectors on the other end.
For eight channels of analog output, the breakout
cable requires a female DB25 connector on one end
and eight male XLR connectors on the other end.
Female XLRs (for V4HD input)
Figure 3-6: Examples of DB25-to-XLR breakout cables (sold
separately). The cable shown on the left has eight female XLR connec-
tors for eight channels of analog input. For output, you would need a
cable with eight male XLR connectors instead. See Appendix D, "DB25
to XLR Pin Outs" page (111) for pin out information.
Within each section (analog in and analog out),
XLR and breakout cable operation are mutually
exclusive. You cannot use both the XLR jacks and
the breakout cable at the same time.
☛
For best performance (and to avoid issues
with termination and impedance levels), do not
connect cables to the rear panel XLR jacks and the
DB25 cable in the same section at the same time.
