Power Connections
There is an IEC mains lead supplied in the package
which should have the correct moulded plug for your
country. The wiring colour code used in all Focusrite
products is:
For units shipped to the USA, Canada, Taiwan and Japan:
Live - Black Neutral - White Earth - Green
For units shipped to any other country:
Live - Brown Neutral - Blue Earth - Green and Yellow
In all modules, the chassis is connected directly to the
mains safety earth. We do not provide an earth lifting
switch, since such a switch can allow for a dangerous
wiring arrangement.
Warning: For safety reasons, it is absolutely IMPERATIVE
that all modules have the mains safety earth connected.
Power Supply
All modules will work correctly from either 50 Hz or 60
Hz power supplies.
Most modules will operate on a range of voltages, and
have a two-position switch on the rear panel that
should be set to the correct voltage:
115V Set to this position if the module is to be
used with voltages in the range 90V to 120V
230V Set to this position if the module is to be
used with voltages in the range 220V to 240V
To comply with the safety codes in some countries,
modules may be supplied without a voltage selector. In
this case, the module is preset to the local supply
voltage, which is clearly marked on the rear of the
module. Check that the voltage is set correctly.
Power Consumption
The processing modules draw approximately 35VA
from the mains supply at highest load.
Signal Connections
All the signal connections are via connectors mounted
on the rear panel. Standard XLR connectors are used
for all mic and line level signals, and are wired to the
AES standards, which are:
Pin 1 Screen chassis
Pin 2 Live audio 0°
Pin 3 Return audio 180°
On every module except for the Red 3 and Red 5, all
inputs and outputs are transformer coupled. (The Red
3 is transformer coupled on the outputs but not at the
inputs, and the Red 5 has no transformer coupling.)
Transformer coupling creates a complete electrical
barrier between all the internal circuitry and power
supply and the outside world, and so removes the
possibility of ground loops. It is designed for balanced
connections: if you want to make unbalanced
connections, you must connect pins 1 and 3 of the
XLR together, as shown in the diagram.
For all inputs and outputs, the screen (pin 1 of the
XLR) is connected to the chassis earth point. When the
screen and earth wiring of the module is completed
correctly, all modules which are marked with the
European Community CE marking comply fully with
the relevant EMC regulations.
