Hooking Up

© Audient v1.0 10/2004



Before starting, it’s always a good idea to
make sure that your monitor speakers are

muted and/or turned off – this ensures

that nothing gets popped or blown up

when cables are being fiddled with and

while power is turned on.

Analogue Connection

(see Figure 1, on next page)

1. Connect the outputs of your

DAW’s interface and any other

sources to Sumo’s inputs. If your

2. Plug the Monitor Outputs of

Sumo into your monitor amplifier,

or directly into your powered

monitors. Make sure you have the

monitor volume right down at this

3. Attach Sumo’s main outputs to

your master recorder such as a

DAT machine or CD recorder, or

even right back into your DAW.

This stage is pretty important,
because you’re converting back

into the digital domain and the

quality of this conversion will

sure to use the best converters you

have available. If you would like to

improve your AD conversion,

consider Sumo’s digital conversion
option, which produces top notch

AES/EBU and S/PDIF straight

out the back of the unit.

If you

are connecting

straight back into your
DAW, you’ll have to make
sure that the track you

record on is either muted or not
routed to Sumo else you’ll get
feedback. And nobody likes
