Power Supply
The Focus EQ will work correctly from either 50 Hz or 60 Hz power supplies, and
draw approximately 35VA from the mains supply at highest load.
The module will operate on a range of voltages, and has 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 85V to 120V
230V
Set to this position if the module is to be used with
voltages in the range 200V to 250V
To comply with the safety codes in some countries, modules may be supplied with-
out 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 cor-
rectly.
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
standard, which are:
Pin 1
Screen
chassis
Pin 2
Live
audio 0°
Pin 3
Return
audio 180°
For all inputs and outputs, the screen (pin 1 of the XLR) is connected to the chassis
earth point.
In the Green range, jack inputs are used only for external switching applications or
as unbalanced guitar inputs on some units.
When the screen and ear th wiring of the module is completed correctly, all modules
which are marked with the European Community CE marking comply fully with the
CE EMC regulations.
