3 Operation
3.1 Operating Precautions
1. Before use, your amplifier must be configured for proper opera-
tion, including input and output wiring hookup. Improper wiring
can result in damage to equipment or potentially harm to the
operator. Consult section 2 for setup instructions.
2. Tampering with the circuitry, or making unauthorized changes
is not only dangerous but may also violate local regulations.
3. Use care when making connections between the amplifier and
the input or output equipment. Using equipment that is not
capable of handling the output wattage may lead to permanent
damage.
NOTE: Stewart Audio will not be held responsible for
damage to your CVA Series amplifier or connected equip-
ment if the instructions in this manual are not followed.
NOTE: For additional operating precautions, please refer
to “Important Safety Instructions” located on Page 2.
2.5.1 Constant Voltage
The Euro Block connector on the rear of the amplifier is capable of sup-
plying output at either 25V or 70V depending on the step-down trans-
formers which will be used in the speaker installation. For information
on specific step-down transformer installation information, please con-
sult the transformer’s manufacturer’s literature.
2.5.2 Wiring Example
