Input Section
MONO Buttons – Under normal
circumstances, all of the odd numbered
channels entering Sumo are routed to the
left side of the bus, while even numbers
are routed to the right. Of course, this is
going to sound a little unusual if your kick
drum appears on the left and your snare is
on the right, etc. So the first two channel
pairs (1/2 + 3/4) can each be mono’d,
effectively panning them dead centre,
right where you want them. Also, routing
mono sources through a single channel
saves outputs from your DAW.
Mix Gain – This control gives you a
pre-dynamics gain trim from –20 to 0dB,
so even if you’ve been especially
normalize-happy whilst editing, you won’t
have any problems with headroom, either
within Sumo or, more likely, with any
attached inserts.
MIX INSERT Switches – These
buttons refer to the insert connections on
the back panel. Use these if you want to
add your own EQ, compression, or
anything else you can think of. The ‘In’
switch puts the inserts in circuit, breaking
the signal path if nothing is connected.
The ‘Post Dyn’ switch allows you to
alterthe position of the inserts in the
chain: before (pre) or after (post) the
internal compressor and limiter.
Be careful of boosting with
an inserted unit when in
post-dynamics mode as the
limiter is no longer able to
protect the output level. This is
particularly important with
digital gear, where overs must
be avoided at all costs.
Output Meter – This meter will
display system output level in dBu for
either the main sum bus or two track
input; whichever is selected in the monitor
section. Or whichever source you are
listening to, if you like. The legend
beneath the meter shows how the
analogue levels relate to digital output
when the digital card is installed. If you
wish to line the analogue inputs of your
digital gear up to match the meters, 0dBu
should equate to –24dBFS.
