Unpacking

The packaging is the simplest that is sufficient to protect the module for shipment. Please keep the
packaging if you are going to ship the module in future.

If this module is to be used in a mobile manner (by this we mean either as a rental unit or on the
road) we very strongly recommend that the module is installed into a high quality flight case which
includes shock protection and suitable ventilation.

We are aware that Ownership Registration cards are not high on your priority list, however we
would be most grateful if you would take the trouble to fill the details in and mail it back to us.
Thank you.

Power Connections

There is an IEC mains lead supplied in the package, which should have the correct moulded plug.
If the plug is incorrect for your location or country, we're sorry. Please replace it the correct
type.

The standard wiring colour code used in all Focusrite products is as follows:

Brown - Live

Blue - Neutral

Green and Yellow - Earth

except for units shipped to the USA and Canada which use this color code:

Black - Live

White - Neutral

Green - Earth

Most modules have two supply voltages ranges, and a switch on the rear panel, marked as follows:

the 115v position is for voltages in the range 100v to 120v.
the 230v position is for voltages in the range 220v to 240v.

Some modules have a four way voltage selector switch. Select the appropriate position for your
mains supply.

To comply with some country’s safety codes the modules may be supplied with the voltage
selector omitted and the module preset to the local supply voltage. In this case the voltage will be
clearly marked on the rear of the module. Please check that this has been set correctly. If incorrect
please refer to the supplying dealer or a competent technician.

All modules will work correctly from either 50Hz or 60Hz supplies. The processing modules draw
approximately 35VA from the mains supply at highest load.
It is absolutely

IMPERATIVE

that all modules have the mains safety earth connected. This is not

a casual suggestion, it is essential for safety reasons.
