Audio Interfaces
The 16 inputs are connected via two
Tascam DA88 type female D-Sub
connectors. Interconnect cables are
readily available in pre-wired form from
Audient and from any good cable
manufacturer. You can get these with
different tail types to suit your other
equipment, see the accessories section on
page 18. Always use balanced connections
to reduce any cable interference and noise.
Outputs are provided on male XLR
connectors: two for the main outs and
two for your monitors.
Inserts are connected via TRS (Tip-Ring-
Sleeve) jacks. Rather than an unbalanced
loop on a single cable, there are separate
jacks for sends and returns, providing
balanced connections throughout.
A third D-Sub connector (which breaks
out to XLRs) can provide extender linking
and an external monitor input. The first
two channels connect the external input
to the monitor section, while the
remaining three pairs of channels allow
additional Sumo units to connect directly
into the mix bus.
All of Sumo’s analogue audio connections
operate at +4dBu, the professional
standard, so you may need to ‘pad’
outputs fed to semi-pro equipment.
