If the setting on your unit is not correct, contact your VIOLA dealer. Only a VIOLA
approved technician should change the voltage setting. Do not attempt to do this
yourself. Should you set the unit to the wrong voltage, you risk personal injury and
you may also cause serious damage to the unit which will void the warranty.
LOCATION
The pre-amplifier should be placed on a rigid stand or shelf. Do not place it on top of
a power amplifier or any other device that handles a large amount of power or may
generate a significant amount of heat. Whilst the power supply may be located on
the same shelf adjacent to the pre-amplifier, it is better if it is located on a separate
shelf.
Always allow a clearance of at least 3.5” (5cm) above the both units. You must also
allow a clearance of at least 6” (15 cm) behind the units, to enable the cables to be
routed without being subject undue strain.
XLR CONNECTOR PIN ASSIGNMENT
CONNECTOR PIN ASSIGNMENT
The pin assignments on the Cadenza’s XLR connectors conform to the AES 14
standard, which is now commonly used throughout the audio industry. These
assignments are shown below:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal - (inverting)
Connector shell: Chassis ground
Some equipment may have the polarity of the signals on pins 2 and 3 of the XLR
connectors swapped over. Please refer to the user manuals of the other equipment
in your signal chain to confirm whether this is the case.
If this is the case, it will not cause any damage, but it may reduce the quality of the
stereo image, as well as the perceived attack of the bass. This situation is easily
remedied by swapping the connections of pins 2 and 3 at either end of one of one set
of balanced cables in the signal chain. Alternatively you can swap over the polarity
of the speaker leads on both channels. Your dealer should be able to advise you on
the best course of action.
