Output modules

The outputs of the X-Amp Series power amplifiers are also de-

signed for easy matching different requirements.

A color-code table provides information about internal output

wiring. When exchanging modules or re-wiring the output connec-

tors, e. g. when using system-cables, inadvertent erroneous con-

nection is virtually impossible. As shipped from the factory, X-Amp

Series power amplifiers are equipped with Xo-1 modules.

The Xo-1 output module provides SPEAKON-type connectors.

When factory-shipped these connectors are assigned to 1+ and

1-; as shown in the diagram. With the X 1201 Single Channel

power amplifier both output connectors are parallel-connected.

This switch separates the enclosure electrically from the ground

potential which helps in preventing "hum-loops". Hum-loops result

from several devices being connected to a mutual ground potential

via mains plugs and, at the same time, when installed in a

rack-system via direct metal contact or through the screen of

connected LF-signal lines. Whenever the power amplifier is instal-

led in a 19" rack system being operated together with other

equipment, the recommended setting of the switch is the GROUN-

DED position. If the power amplifier is used together with applian-

ces that are connected to different ground potentials, the

recommended setting is UNGROUNDED.

The grounding screw is located next to the ground-lift switch and

is meant for the connection of an "earth bar". Whenever several

devices are installed in a rack-system, they should be connected

to a common ground, since their lacquered front panels may avert

sufficient galvanic inter-connection between the enclosures.
