7. Mains is supplied via an IEC standard 3 pin connector. A compatible power cord is supplied
with the unit.
8. The mains fuse is located in the draw that is part of the mains input connector. A spare fuse is
also stored here. Disconnect the unit from the mains supply before replacing the fuse. Always
replace the fuse with the correct type and rating.
9. Two sockets are provided for the connection of the 24V DC supply. These are standard
4mm ‘banana’ type. The sockets are on a standard 19mm pitch to allow the use of twin stackable
connectors. The polarity of the DC supply must be maintained for operation though incorrect
connection will not damage the unit.
10. Input and output connections are via complementary XLR style connectors. For wiring
details see the page entitled Audio Connections.
NOTE: The security cover is normally fixed with M3 pozidrive screws. For installations where
the utmost security is required these can be replaced with tamperproof type of M3 x 6mm.

Inputs
The input circuitry is a transformerless, electronically balanced design which achieves a symmetry of
better than -50dB from 20Hz to 10kHz.
It is always preferable to drive the equaliser from a balanced source. If only an unbalanced source
is available it is recommended that it is connected as shown below. Connect the screen only at the
equaliser end.
