REAR PANEL/ INSTALLATION CONSIDERATIONS
1.
IEC AC INLET:
Connect the socket end of the mains cable provided with this unit to this socket and
the plug end to a 230V AC outlet. Ensure that the ground pin of the AC outlet has a firm connection
with the earth of the premises. This is both in the interests of your own safety as well as to eliminate
ground related hum and buzz problems.
2.
OUTPUT CONNECTORS:
Two types of output connectors are provided for output connections:
male XLR type connectors and 1/4” tip-ring-sleeve phone jack connectors.
3.
INPUT CONNECTORS:
Two types of input connectors are provided for input connections:
female locking XLR type connectors and 1/4” tip-ring-sleeve phone jack connectors. The maximum
input level that the equalizer can accept without clipping is +22dBu (ref: 0.775Vrms)
INSTALLATION CONSIDERATIONS
HOOKUPS AND CABLING:
The Equaliser is designed for n4dBu levels. The equalizer can
be used with either balanced or unbalanced sources, and the outputs can be used with either balanced or
unbalanced loads, provided the proper cabling is used.
INPUT CABLE CONFIGURATIONS:
The equalizer has an input impedance of 40kΩ balanced and
20kΩ unbalanced. This makes the Equalizer’s audio inputs suitable for use with virtually any low source
impedance (under 2kΩ).
OUTPUT CABLE CONFIGURATIONS:
The equalizer’s output is capable of driving a 600Ω load to
+18dBu. For maximum hum rejection with a balanced source, avoid common grounding at the equalizer’s
inputs and outputs. Most balanced (3-conductor) cables have the shield connected at both ends. This can
result in ground loops which cause hum. If hum persists try disconnecting the shield on one or more of the
cables in the system, preferably at the input of a device, not at the output.
