Mains Socket
Please, make sure to check whether the voltage selector shows the correct mains
voltage that matches the local mains supply at the installation site. An appropriate
mains cord is included in the package.
Input
The inputs INPUT CHA \ CHB are connect to mixing consoles. The XLR-type
connecting OUTPUT
are prepared for through-connecting input CHA \ CHB
signals to additional external power amp s. The input signal is directly routed to these
output connectors. Accordingly, input and output connectors of the corresponding
channel are interconnected in parallel, offering permanent electrical connection,
without regard to the setting of the Power-ON switch.
Although having XLR-type output connectors, some mixing console models provide
unbalanced output connection only. when using mixers with unbalanced outputs,
bridging PIN1 and PIN3 of the power amp s input connectors or leaving PIN3 of the
cable s plugs unconnected is necessary. Otherwise, when feeding in unbalanced
audio signals via PIN3 (B,-, cold) and PIN2 (A , + , hot), strange humming and HF-
interference may occur, which very likely will damage the power amplifier and /or the
connected speaker cabinets.

LF- connection cords
Choosing high-quality balanced cables( two conductors for the audio signal plus sepearate shielding
mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting
unbalanced cables to the power amplifier inputs is possible as well, using balanced cables is always
preferable. A great number of today s audio appliances employ balanced outputs. With balanced cabling,
the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction of
external interference-mostly noise and hum.
